NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020

1 Summary

Wolf Acquisition Corp. (“Wolf”) and Frontera Gold Inc. (“Frontera”) retained Brian T. Brewer, CPG, M.Sc. of Brewer Exploration and Geological Services, Inc. of Salmon, Idaho in August 2020 to prepare an independent technical report (the “Technical Report”) on the Hot Springs gold project (the “Property”) in compliance with regulatory disclosure and reporting requirements in National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), NI 43- 101CP and Form 43-101F1 – Technical Report (“Form 43-101F1”). Mark Smethurst M.Sc., P.Geo., is a co-author on the Technical Report contributing research and background. The purpose of this report is to review and summarize exploration on the Property and to provide recommendations for future work.

The Property is located within the Getchell Gold Trend in north-central Nevada approximately 25 miles east of the Twin Creeks, Getchell and Pinson Mines. The Property currently consists of approximately 11,894 acres comprised of a combination of private land (approximately 6,720 acres) and unpatented lode mining claims on Bureau of Land Management (“BLM”) managed lands (267 claims, approximately 5,174 acres). The Property encompasses the historic Dutch Flats gold shear zone.

Frontera is a private Canadian incorporated under the Business Corporations Act (British Columbia). On October 13, 2020, pursuant to an option agreement dated September 3, 2020 and entered into between Frontera Gold Nevada Inc., a wholly owned Nevada incorporated subsidiary of Frontera, and Osgood Mountains Gold, LLC (“OMG”), Frontera exercised its option to acquire a 50% interest in the Property.

On December 17, 2020, Frontera entered into a business combination agreement with Wolf (TSXV: WOLF), and CX One Inc. (“CX1”), under which Frontera and CX1 intend to complete a reverse takeover of Wolf, resulting in Wolf acquiring all of the issued and outstanding securities of Frontera and CX1 (the “Qualifying Transaction”).

Previous exploration has identified numerous, widespread, high-grade gold occurrences within a northeasterly-trending zone of deformation (fault zone). Geological mapping has identified this zone to be approximately 3,400 feet wide with an identified strike length of approximately 10,000 feet. Historically, this main fault zone has been referred to as the Dutch Flats Fault Zone which hosts numerous, intermittently exposed quartz-filled faults and shears. Ninety-one (91) reverse circulation (RC) holes have been drilled in the main Dutch Flats area totaling 26,825 feet. As a result of this drilling, Duerr (1994) identified a non-NI 43-101 compliant drill-indicated estimation of tons and grade of approximately 10 million tons grading 0.008 opt Au for 80,000 ounces of Au. Recent modeling completed by OMG has identified a non-NI 43-101 compliant estimation of tons

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 and grade of approximately 16 million tons grading 0.179 ppm Au for 91,570 ounces total contained Au. Both the Duerr (1994) and OMG models suggest that the drill-indicated Au mineralization on the Property is open along strike, both to the northeast and southwest, and at depth.

Recent sampling on the Property has confirmed the historic data of widespread high-grade gold occurrences on the property. Duerr (1994) reported surface samples with values up to 0.66 opt Au taken from outside the drill-indicated resource area. Results of previous exploration efforts also suggest that a second mineralized structure which parallels the Dutch Flats Fault Zone may exist approximately 1,000 feet to the east. It is also possible that the Dutch Flats Fault Zone is a splay off of the northerly-trending Range Front Fault that is hypothesized to be located under the pediment to the west of the property. If true, then the juncture of these two faults may represent another viable exploration target. These high-grade Au samples along with widespread high As, Hg and Sb occurrences suggest that the Property may be host to a significant low-sulphidation Epithermal gold deposit similar to the Sleeper, Midas, Round Mountain and Hycroft deposits. 1.1 Property Description

The Property is located in the Dutch Flats Mining District, Humboldt County, Nevada approximately 22 miles northeast of Winnemucca. The Property comprises portions of sections 1, 3, 4, 5, 6, 8, 9, 10, 11, 15, 16, 17, 18, 20 & 21 Township 38 North, Range 40 East and sections 25, 27, 33, 34 & 35 Township 39 North, Range 40 East Mount Diablo Meridian as shown on the Delvada Spring and Gumboot Lake 7.5’ USGS quadrangle maps. The approximate center of the Property is WGS 84 Zone 11T, 458560 m E 4558275 m N.

The Property is accessible by vehicle by travelling approximately 19 miles north of Winnemucca on U.S. Highway 95 thence approximately 7 miles east on the well-maintained Dutch Flats Road. Several unmaintained gravel and dirt roads and ATV trails splay off of Dutch Flats Road and provide access to much of the property.

1.2 Mineral Tenure

The Property is located within the Getchell Gold Trend in north-central Nevada approximately 25 miles east of the Twin Creeks, Getchell and Pinson Mines. The Property currently consists of approximately 11,894 acres comprised of a combination of patented mining claims (~6,720 ac) and unpatented lode mining claims on BLM managed lands (267 claims, ~5,174 ac) (Figure2). The Property encompasses the historic Dutch Flats gold deposit.

A review of the BLM’s Legacy Rehost System, LR2000, was conducted in order to examine the status of all unpatented lode mining claims on the Property (Table 1). According to LR2000, all unpatented lode mining claims comprising the Property are currently active (valid) as of the date of this report and held by OMG. An annual maintenance fee of $165.00 per claim is due by September 1st of each year in order to maintain this status. Unpatented lode mining claims grant the holder(s) of the claims all mineral rights for lode deposits contained within the boundary of the claims. The holder(s) of the claims can sell, option or lease these rights at their discretion.

A search and review of records from Humboldt County and the Nevada Secretary of State on OMG, the Lessors (as defined below), and the patented mining claims was conducted. According to the Humboldt County and the Nevada Secretary of State OMG did not owe any property taxes on their unpatented lode mining claims, was in good standing with the state, and had no record of tax liens or other encumbrances applied to the patented mining claims. All patented mining claims (private property) under the Property and its mineral rights are held under a mining lease agreement (the “Mining Lease”) between Buttonpoint Limited Partnership, a Nevada Limited partnership, Crawford Cattle LLC, a Nevada limited liability company, Nevada Crawford Recovery, LLC, a Nevada limited liability company, Eldon S. Crawford and Brenda D Crawford, trustees under the Crawford Family Living Trust dated March 17, 2004 (collectively, the “Lessors”) and OMG on August 1, 2016 (the “Acceptance Date”). The Mining Lease continues for five (5) years after the Acceptance Date with four (4) extension terms of twenty (20) years each and one (1) extension term of fourteen (14) years, for an effective term of ninety-nine (99) years. Pursuant to the Mining Lease and most recent amendment to the Mining Lease dated April 23, 2020 (the “Third Mining Lease Amendment”), the minimum payments to be paid by OMG to the Lessors (the “Minimum Royalty Payments”) has been duly paid up to August 1, 2020 equaling approximately $25,000 in relation to the patented mining claims of the Property. Minimum Royalty Payments of approximately $25,000 is due on the next three (3) subsequent anniversary dates of the Acceptance Date, being August 1, 2021, August 1, 2022, and August 1, 2023. Subsequent to the aforementioned Minimum Royalty Payments, each successive payment, beginning on the eighth anniversary, being August 1, 2024, will consist of $12.50 per acre or approximately $24,000 coming due on certain parcels and sections described in the Third Mining

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 Lease Amendment related to the Property. There are no other annual holding costs. Annual property taxes are the responsibility of the Lessors. There are also additional obligations pursuant to earlier amendments to the Mining Lease. An amendment to the Mining Lease dated October 12, 2017 (the “First Mining Lease Amendment”) entitles the Lessors to a 1.5% Gross Revenue Royalty (“GRR”) on future minerals production by OMG. A subsequent amendment to the Mining Lease dated August 15, 2016 (the “Second Mining Lease Amendment”) adjusted the Acceptance Date of the Mining Lease to August 15, 2016, with Minimum Royalty Payments being $250,000 on the Acceptance Date and first anniversary date subsequent to the Acceptance Date; $500,000 on July 31, 2018; $250,000 on the third anniversary of the Acceptance Date; and on the fourth and each succeeding anniversary of the Acceptance Date, $12.50 per acre on all leased portions by OMG. On September 3, 2020, OMG entered into an option agreement (the “Option Agreement”) with Frontera. Pursuant to the terms of the Option Agreement, Frontera has the option to fund a current work program (the "Program") for the Property totaling US$670,000 in two (2) equal payments of $335,000 each. Upon funding of the Program, Frontera will earn a 50% interest in a joint venture which solely owns and operates the Hot Springs gold project. Frontera has funded these amounts, thereby automatically converting its option on the Property into an interest of 50% of a joint venture, which will operate the exploration and development programs for the Property.

1.3 Geology and Mineralization

The regional geology of the Property is dominated by the north-south trending Basin and Range physiographic province of northern Nevada. Exposed rocks in the region range in age from Cambrian to Tertiary and comprise thick sequences of sedimentary, volcanic, intrusive and metamorphic rocks in a complex structural environment (Zenda Gold Corp., 1997). Rocks on the Property are mainly composed of thick sequences of folded, Cambrian to Permian, marine siliciclastic and carbonate sedimentary units, with lesser amounts of altered mafic marine volcanic (greenstone and debris flow) rocks and chert. Total thickness of these units is estimated to be more than 5,000ft (~1,670m), a more thorough understanding of the dimensions of the units is complicated due to the complexity of folding, thrust faults, and lack of exposure of the base of some units. These rocks were then intruded by the Late Cretaceous granodiorite stock, and mid- to late-Miocene age basaltic lava flows are found along flanks of ranges found on the property above a major unconformity. The Property is underlain by Cambrian-aged clastic and chemical sedimentary rock of the Harmony Formation including mudstone, shaly siltstone, sandstone, feldspathic greywacke, quartz pebble conglomerate, chert and limestone. The sedimentary rock generally strikes northeasterly (030 to 040 degrees) and dip shallowly to moderately to the southeast (16 to 70 degrees). These rocks are typically reddish-brown, poorly bedded, massive to locally well-foliated (sheared) and moderately to locally strongly fractured. These rocks are locally strongly argillized, especially within the shear zones. Rare-graded beds fine (and presumably young) to the southeast. Joints and fractures are commonly filled with veinlets/stringers of quartz and/or calcite. In the southeastern part of the property the sedimentary rocks have been intruded by a small quartz monzonite stock of Tertiary age. This stock is exposed over an area of about 2,000 feet by 1,200 feet. The stock is cut by El Paso Gulch, which forms a pronounced narrow valley in rocks that are yellowish- to reddish-brown in color due to oxidation of pyrite and mafic minerals, primarily biotite. Unaltered outcrops are light grey, medium-grained and equigranular. Locally, border phases and dykes may be granitic or granodioritic, these intrusions are strongly hydrothermally altered, silicification has been observed in nearby outcrops. A similar felsic intrusion also occurs in the southwestern area of the Property. The size of this intrusion is unknown. The sedimentary rocks adjacent to the margins of these felsic intrusions have been locally metasomatized and variably altered (argillized, sericitized, silicified, carbonatized and hematitized). Thin remnants of Tertiary-aged basalt cap the ridges around the Property and form a pronounced peak known as Belmont Hill. (Zenda Gold Corp., 1997). To the east of the Property are the Getchell, Turquoise Ridge, Twin Creeks and Pinson mines that hold Carlin-type disseminated gold mineralization, nearly 19 million ounces of gold have been produced from the sedimentary rocks of these Carlin-type gold deposits. These deposits were formed mainly during the late Eocene time within marine sedimentary units originally formed in

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 the Late Cambrian and Early Ordovician. Carlin-type deposits are sediment hosted gold deposits fed by deeper structures. To the northwest is the Sleeper deposit with a similar deposit type as the Hot Springs property. The Sleeper deposit is a low-sulphide epithermal deposit with bonanza gold-silver veins. The stockwork veins and breccia commonly contain 1-5g/t gold, with reported bonanza veins up to 4m wide of 50-100 g/t gold.

1.4 Exploration, Development and Operations

There is no current exploration, development or operations on the Property. However, evidence of past mineral exploration and production is evident throughout the Property. The first reported mineral exploration on the Property occurred in 1893 when F.G. Wendall discovered placer deposits of gold, scheelite and cinnabar near the mouth of Sodarisi Canyon and along El Paso Gulch. Vanderburg (1936) reports that approximately $200,000 worth of gold and 90 flasks of mercury were produced from the area from numerous pits (116), trenches (27), adits (45) and shafts (21) along auriferous quartz veins.

1.5 Conclusions and Recommendations

The Property is located in the Getchell Gold Trend in north-central Nevada. The property has had sporadic exploration efforts but appears to have lacked a concerted systematic exploration program conducted on it.

Previous exploration efforts have identified numerous, widespread, high-grade Au occurrences on the Property. Historic and recent surface sampling has identified high As, Hg and Sb values associated with Au which can be indicative of a geological environment associated with the upper zone of a low-sulphidation epithermal system similar to the Sleeper, Midas, Round Mountain and Hycroft deposits.

While the bulk of the known Au mineralization occurs within the Dutch Flats Fault Zone in the area of historic mining operations, potential exists for other targets outside of this zone. Most notably, the anomalous area identified by soil samples to the east, and parallel to, the Dutch Flats Fault Zone, the hypothesized juncture of the Dutch Flats Fault Zone and the Range Front Fault to the west, and along the mineralized shear zone itself in both directions. The author recommends that Frontera continues to conduct systematic exploration of the Hot Springs Property to better define the known gold resource, test previously identified targets that include the undelineated structure that is parallel to the Dutch Flats shear zone, and five areas of interest that returned mineralization values in and around the historic mine locations and to potentially identify additional target areas. The geological setting of the Property lends itself to be a viable host to a significant low-sulphidation epithermal gold deposit.

Upon funding of the Program, Frontera will earn a 50% interest in a joint venture which solely owns and operates the Hot Springs Project. Frontera has funded the Program as of the date of this Technical Report, thereby converting its option on the Property into a 50% undivided joint venture interest, which will operate the exploration and development programs for the Property.

The Property is accessible through publicly maintained access routes. The author and co-author are not aware of any restrictions that would limit access or permissions required to gain access to any private lands associated with the Mining Lease.

4.3 Environmental Liabilities

The author is not aware of any environmental liabilities associated with the Property.

4.4 Required Permits

OMG has received approval for a NOI level drill program to be conducted on the Hot Springs Property. This NOI allows the operator to construct six (6) drill pads for the purpose of completing a diamond core drill program on the Property. If necessary, an amended NOI could be submitted to either add additional drill sites and/or move the location of the currently permitted sites. It is anticipated that any such minor revisions would be approved in a timely manner.

A reclamation bond is required for any surface disturbing activity.

Any surface disturbing activity conducted on the private lands portion of the Property will be administered by the Nevada Division of Environmental Protection’s (“NDEP”) Bureau of Mining Regulation and Reclamation (“BMRR”) office in Carson City, Nevada. Nevada statutes established three levels of authorization for exploration and mining operations on private lands: (1) casual use, (2) NOI, and (3) Plans of Operations (“POO”). NOI level permitting will be required for road

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 and drill-site construction that total less than 5 acres of disturbance, whereas a plan of operations will be required for total disturbance exceeding 5 acres. Reclamation bonding is required for both NOI and POO levels of disturbance and permitting.

The Property is partially located on lands administered by the BLM. Non-surface disturbing activities such as the collection of soil samples and ground geophysics will not require any permit. Any additional drilling conducted on the BLM lands portion of the Property outside the scope of the approved NOI would require a permit before any such activity could commence. An NOI level permit is required for any surface disturbing activity of up to 5 acres, which would also require a reclamation bond.

Frontera’s current work plan can be conducted under the currently approved NOI which was acquired by OMG. It is expected that future exploration work conducted by Frontera can be completed under a similar NOI which will require a reclamation bond.

4.5 Other Significant Factors and Risks

The author is not aware of any other significant factors or risks associated with the Property.

5 Accessibility, Climate, Local Resources, Infrastructure, and Physiography

5.1 Accessibility, Infrastructure and Local Resources

The Property is accessible by vehicle by travelling approximately 19 miles north of Winnemucca on U.S. Highway 95 thence approximately 7 miles east on Dutch Flats Road, as seen in Figure 8. Several unmaintained gravel and dirt roads and ATV trails splay off of Dutch Flats Road and provide access to much of the Property. The Property can also be accessed by helicopter from local services in the City of Winnemucca.

Interstate highway I-80 and the Union Pacific Railroad line are located at the city of Winnemucca. Northern Nevada in general, and specifically, Winnemucca, Elko and Reno are well-known for skilled mining and construction labor. Winnemucca (population of ~8,000 in 2020) also offers a wide range of accommodation, fuel, retail, mining and industrial services and equipment.

Power lines are located within 7 miles from the Property and offer potential line power sources for future development.

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 Surface water exists throughout the year in several places within the Hot Springs property, in stock ponds and perennial streams. Under an agreement with the ranch owner, several existing irrigation wells for agricultural use within the leased sections could be potential sources for water necessary for exploration drilling. To obtain permission to use water for drilling purposes, a “Request for a Waiver for Temporary Use of Ground Water for Mineral Exploration” must be granted by the Office of the State Engineer of Nevada. These requests are simple and prompt approval for any such request is expected.

Surface rights for the private property under lease are maintained and transferred by the landowner in accordance with the Mining Lease. All surface rights for BLM-managed lands remain under authority of the BLM. Any surface disturbing activity will require a permit as detailed in Section 4.4 of this Technical Report.

5.2 Topography, Elevation and Vegetation The Property varies from rugged, mountainous and hilly areas, to gently sloping, nearly flat alluvial aprons and open valley bottoms in Eden Valley and the southern part of Paradise Valley. Elevations range from about 4,350 ft above sea level in the southern parts of Eden and Paradise Valley, to a high point of 6,962 ft above sea level in the central part of the Hot Springs Range. Elevations along the crest of the Osgood Mountains are higher, reaching a maximum of about 8,680 ft above sea level. A more detailed description of the area was given by Hotz and Willden (1964), who stated “The topography of the Osgood Mountains is more rugged and less uniform than that of the Hot Springs Range. In the Hot Springs Range rather uniform dissection has resulted in topography of monotonous aspect. Many short steep-sided canyons, each with a multitude of steeper subsidiary ravines and gullies and narrow smooth-surfaced divides, lead eastward or westward from the narrow north-trending crest to the alluvial aprons at the base of the range. The crest of the range east of Dutch Flat and extending southward for about 2 miles is a rather broad surface of gentle relief; but in general, the canyons, ravines, and gullies and the slopes between them resemble their counterparts elsewhere in the range, and there is a general lack of eye-catching forms. The Osgood Mountains, on the other hand, have a considerably varied topography. In the southern part of the range the summit areas are commonly gently rolling surfaces which drop off abruptly to steep slopes below. The central and northcentral parts of the range have high narrow ridges, long relatively smooth steep slopes, some bold clifflike features, and several large valleys, amphitheaterlike at their heads, narrow and steeper toward the range front. The north end of the range is thoroughly dissected by many short ravines and gullies. The east front is fairly straight, and in the northern part several of the east trending ridges are terminated with subtriangular facets; in the southern and central parts the mountain front is fairly steep but descends gradually into gentler pediment slopes veneered with gravel that grades into the valley alluvium. The west front is considerably more irregular and is marked by several reentrants and mountain spurs that project into the valley.”

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 Vegetation is sparse over much of the Property, consisting mainly of mixed sagebrush and grasses. The Hot Springs Range and the Osgood Mountains are almost devoid of trees, except for a few aspens in the upper parts of some canyons. During the spring, many kinds of small flowering plants are plentiful. Typical fauna includes mule deer, coyotes, antelope, jackrabbits, and small rodents. 5.3 Climate

Climate in the Hot Springs project area can be described as semi-arid and continental, with hot summers and cold winters. Summer high temperatures may infrequently reach as high as 105°F. Winter low temperatures may infrequently reach as low as -20°F. Annual precipitation in terms of equivalent rainfall averages about 8.25 in, which falls chiefly as snow during the winter and early spring (Table 2). Occasional thunderstorms bring some rain during the summer. The average annual snowfall is 21 inches at the lower elevations, based on records for Winnemucca, Nevada. Snowfall at the upper elevations of the project area can be greater. Mining and exploration can be conducted year-round, though snow removal may be required to keep roads passable at times during the winter.

6 History

The first reported mineral exploration on the Property occurred in 1893 when Fred G. Wendall discovered placer deposits of gold, scheelite and cinnabar near the mouth of Sodarisi Canyon and along El Paso Gulch. Mr. Wendall operated a placer gold mine employing approximately 20 men for several years following his initial discovery. Vanderburg (1936) reports the discovery of a gold nugget valued at $180 (approximately 9.5 oz). Vanderburg (1936) also reports that approximately $200,000 worth of gold and 90 flasks of mercury were produced from the area

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 from numerous trenches, adits and shafts along auriferous quartz veins. Willden and Hotz (1955) provided a review and assessment of the property stating that the gold is coarse, angular, attached to a quartz matrix and that the quartz veining source is local having travelled over a short distance. Willden and Hotz (1955) make brief mention of mining operations through the 1940’s into the early 1950’s by Dutch Flat Mines Inc. Lode claims owned by Dutch Flat Mines Inc. had 10 small mines with an aggregate of 4,000 feet of underground workings, among these mines is the El Paso Mine that reported pockets of ore running $200 in gold per 50-pound ore sack.

Several mineral exploration companies and numerous individual claimants have held mining claims (mineral rights) on the Property, and several have conducted exploration activities on the Property in modern history. The Company has possession of, and the author has reviewed, historical documents and data including, drill logs, assay data, geophysical data, field notes and summary reports from much of the significant work programs detailed below. 6.1 Brican Resources

Brican Resources (“Brican”) conducted geochemical and geophysical surveys followed by completing thirty-two (32) shallow, vertical RC holes (B-1 through B-32) for a total of 8,520 feet during 1985 and 1986. Cox (1996) reports that Brican intersected gold mineralization in fifteen (15) of these holes one of which (B-21) intersected 32.5 gpt gold over 1.5m at a shallow depth of approximately 30m within the Dutch Flats shear zone. Hole B-21 also intersected 4.8 gpt gold over 1.5m at an approximate depth of 10m Drill hole lengths ranged from 100 feet to 340 feet, and sample intervals were at 5 feet (1.5m). The next highest-grade holes were B-16 at 3.5 gpt over 1.5m, and B-18 at 3.2 gpt over 1.5m. The remaining drill holes ranged in grade from nil to 1.4 gpt over 1.5m intervals. A digital database containing the aforementioned drill logs was made available to Frontera Gold Inc.

Brican completed a ground VLF-EM survey on the Property which indicates the presence of significant conductive trends. Specifically, the Annapolis reading indicated the presence of a conductor axis in the Belmont Shaft area and both stations indicate structures which appear to offset this mineralization trend (Zenda Gold Corp., 1997). 6.2 AMAX Exploration Inc.

AMAX Exploration Inc. (“AMAX”) drilled 18 shallow, inclined RC holes (A-1 through A-18) totaling 6,161 feet during 1987 to 1988. Cox (1996) reports that AMAX intersected gold mineralization in eleven (11) of these holes. Based on their drilling, AMAX reportedly calculated an estimation of grade and tons of approximately 3 million tons grading less than 0.03 opt Au showing a zone of mineralization within the Dutch Flats shear zone. AMAX also completed preliminary metallurgical studies by conducting cyanide shake tests on drill chip composites. Initial results indicated that gold recoveries up to 90% could be expected from cyanidation.

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 The author and co-author have not reviewed the grade and tonnage estimates reported by AMAX. This historical resource does not use the classification terms “Inferred Mineral Resource,” “Indicated Mineral Resource,” and “Measured Mineral Resource. A qualified person has not done sufficient work to classify this historic estimate as a current Mineral Resource or Mineral Reserve and Frontera and Wolf are not treating the historical estimate as current Mineral Resources or Mineral Reserves. AMAX reportedly completed a detailed IP/resistivity survey on the Property, but the original data and results are not available. 6.3 Homestake Mining

Homestake Mining drilled five (5) shallow holes in the pediment west of the Brican and AMAX drilling. Results of this drilling are unknown to the author. 6.4 Zenda Gold Corp.

Zenda Gold Corp. (“Zenda”) spent a total of 80-man days on the Property in March and April 1997. During this time, they completed detailed geological mapping of the Dutch Flats Mine and El Paso Mine area, lithogeochemical sampling and soil sampling.

177 rock samples were collected and assayed for Au, Ag, As, Hg and Sb utilizing fire assay and atomic absorption finish methodologies by American Assay laboratories of Sparks, Nevada. Zenda Gold Corp. (1997) report that 47 samples (26.5%) returned values greater than 100 ppb Au (0.003 opt Au) and 8 samples (4.5%) returned values greater than 1,000 ppb Au (0.03 opt Au). They report one select grab sample that returned a value of 7,079 ppb Au (0.21 opt Au) from the El Paso area and two 8-foot chip samples that returned values of 1,112 ppb (0.03 opt Au) and 1,590 ppb (0.05 opt Au) from the Canyon and El Paso areas respectively. Significant amounts of Ag, As, Hg and Sb were also reported with the highest reported values being as follows; 500 ppm (14.5 opt) Ag, 7,070 ppm (0.71%) As, 154,240 ppb (0.02%) Hg and 4,498 ppm (0.45%) Sb.

Zenda collected 1,166 soil samples at 100-foot intervals along lines spaced 400-feet apart. The samples were analyzed for Au, Ag, As, Hg and Sb by American Assay Laboratories of Sparks, Nevada. Au assays were obtained by fire assay with an atomic absorption finish and Ag, As, Hg and Sb values were obtained by atomic absorption spectroscopy. Au values ranged from below detection limit to a high of 326 ppb (0.009 opt). High values for As and Hg were 86 ppm and 263,070 ppb respectively. This soil sampling program identified a large area (approximately 3,500 feet by 3,500 feet) that contains numerous Au, As and Hg anomalies and extends well beyond the boundaries of the drill-defined Au resource (Zenda Gold Corp., 1997).

Nineteen (19) samples were also collected for BLEG analysis.

Based on previous drilling through the Dutch Flats shear zone in the area of the historic El Paso mine and Belmont Shaft, Zenda notes a mineralization estimate of approximately 10 million tons grading 0.008 opt Au for 80,000 oz of contained gold calculated by Duerr (1994). Zenda notes the

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 mineralization described in the estimate is open along strike to the northeast and southeast and at depth along the shear zone. Frontera considers the estimate to be important as target generating information only. The author and co-author have not reviewed the grade and tonnage estimates reported by Zenda. This historical resource does not use the classification terms “Inferred Mineral Resource,” “Indicated Mineral Resource,” and “Measured Mineral Resource. A qualified person has not done sufficient work to classify this historic estimate as a current Mineral Resource or Mineral Reserve and Frontera and Wolf are not treating the historical estimate as current Mineral Resources or Mineral Reserves.

The results of this work identified 5 areas of interest for gold mineralization around the historic mine locations, and a new linear target, possibly a structure, parallel to the Dutch Flats shear zone and located approximately 300m to the east that is yet to have its bounds delineated. In addition, the report recommended survey programs to locate the intersection of the Dutch Flats shear zone with the Range Front Fault towards the southwest, this structural intersection holds the possibility of containing gold mineralization at significant grade. 6.5 Cordex Exploration

Cordex Exploration completed 41 RC drill holes (DF1 through DF41) on the Property in 2006 and 2007 with several holes encountering significant Au mineralization, as detailed in Table 3 below. 6.6 OMG

In 2019 OMG has collected a total of 111 surface rock samples from the property which have resulted in significant amounts of Au, Ag, As, Hg and Sb assays. Of the 111 samples collected, 12 (10.8%) returned values greater than 1 ppm Au and 49.5% (55 samples) returned values greater than 0.1 ppm Au (Figure 3).

Based on historic drilling data performed by previous owners, OMG has identified a non 43-101 compliant estimation of tons and grade of approximately 16 million tons grading 0.18 g/t Au for 91,750 Troy ounces Au. This zone of mineralization remains open along strike to the northeast and southwest as well as at depth. It is likely that additional exploration and drilling will expand this zone of mineralization significantly.

The author and co-author have not reviewed the grade and tonnage estimates reported by OMG. A qualified person has not done sufficient work to classify this historic estimate as a current Mineral Resource or Mineral Reserve and Wolf and Frontera are not treating the historical estimate as current Mineral Resources or Mineral Reserves.

6.7 Drilling

A total of 91 reverse-circulation (RC) holes have been drilled on the Property for a total of 26,825 feet (Figure 4). All drilling has been concentrated in the general Dutch Flats Mine area. All drill hole samples were assayed for Au. However, samples from only 24 holes (10,190 feet of samples, or 37.99% of total drill footage) were analyzed for multi-element geochemistry (pathfinder elements). The highest reported gold value from a 5-foot drill hole sample is 32.53 ppm Au (hole B-21). The average gold value for all reported drill hole samples is 0.0729 ppm Au. Significant drill results are highlighted below (Table 3).

7 Geological Setting and Mineralization

7.1 Regional Geology

The Property is located in north-central Nevada, an area which is dominated by two north- northeast-trending mountain ranges, the Osgood Mountains to the east and the Hot Springs Range to the west. The mountain ranges are located to the north and northeast of Winnemucca, the principal town in the region. The mountain ranges are separated by a narrow valley and are bounded on the east and west by broad alluvial basins. This area has grown with importance over time due to discoveries and mining of tungsten and gold. In the early 1940’s small productions of quicksilver and gold came from deposits in the Dutch Flats area in the Hot Springs Range (Hotz, P. E., et al., 1964). Known today as the Hot Springs gold project, it is located about 35km northeast of Winnemucca (Willden, R., et al., 1955). More recent development of a similar deposit type to the Hot Springs property is demonstrated by the Sleeper deposit located about 45 km to the northwest of Winnemucca. The Sleeper deposit is a low-sulphide epithermal deposit with bonanza gold-silver veins. The stockwork veins and breccias commonly contained 1-5 g/t gold, with reported bonanza veins up to 4m wide of 50-100 g/t gold (Saunders, J.A., 1994), with significant intercepts more than 300m deeper, with vein continuity extending over 500m (Nash, J.T., et al., 1989). The author and co-author have not reviewed the grade and intercept estimates reported by Saunders, J.A., 1994, and do not offer an opinion as to their validity and accuracy as part of this Technical Report. The Osgood Mountains and the Hot Springs Range provide for one of the dominant sources of information for understanding the regional geology. Paleozoic rocks exposed include strata of Cambrian, Ordovician, Mississippian, Pennsylvanian, and Permian age (Hotz, P. E., et al., 1964). Cambrian age units, from oldest to youngest, consist of the Osgood Mountain quartzite dominated by cross-bedded quartzite with some thin shaly rocks. The Preble Formation is predominantly shale but includes a few quartzite beds in its lower part and is composed of interbedded limestone and shale in the middle and upper part of the section. The next youngest unit is the Paradise Valley chert of Late Cambrian age. The formation is predominantly chert but includes some thin beds of shale and limestone. The uppermost Cambrian unit is the Harmony Formation, which rests in depositional contact on the Paradise Valley chert. The Harmony Formation makes up most of the Hot Springs Range and is found across the Hot Springs property. Feldspathic sandstone and shale are the predominant rock types of the Harmony Formation, but the formation also includes some limestone and a little chert (Hotz, P. E., et al., 1964). Ordovician units consist of the Comus Formation of Early and Middle Ordvician age is predominantly an alternating sequence of dolomite, limestone, and shale, with lesser amounts

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 of chert, siltstone, and tuffaceous material. The Valmy Formation is Early, Middle, and Late Ordovician age and are dominated by chert and siliceous shale. Structurally, the Comus Formation is regarded as autochthonous, whereas the Valmy Formation is thought to have been brought into the area by thrust faulting (Hotz, P. E., et al., 1964). The canyon Formation is composed mostly of altered volcanic rocks of medium to basic composition and coarse-grained fossiliferous limestone, and minor amounts of calcareous shale, siliceous shale, and chert. Structurally, the formation occupies a thrust plate in the Osgood Mountains, its stratigraphic relations with other Paleozoic rocks are not known (Hotz, P. E., et al., 1964). Middle Pennsylvanian to Late Pennsylvanian and Early Permian age strata rest unconformably on the older Paleozoic rocks. The Battle Formation is predominantly a conglomerate of Middle Pennsylvanian age, which underlies and interfingers with the Etchart limestone of Middle Pennsylvanian to Late Pennsylvanian or Early Permian age. The Etchart limestone is predominantly a sequence of limestone and sandy limestone, with some interbedded dolomite, minor amounts of calcareous shale, and lenticular beds of conglomerate. Also, of the same age as the Etchart limestone, the Adam Peak Formation, has been thrust over the Etchart limestone. The Adam Peak Formation is composed of shale, siltstone, dolomitic sandstone, and chert (Hotz, P. E., et al., 1964). The Farrel Canyon Formation is a sequence of sandstone, shale, chert, and altered volcanic rock and outcrops in the northwestern part of the Osgood Mountains, the stratigraphic position is uncertain (Hotz, P. E., et al., 1964). One large intrusive body of granodiorite cuts the Preble Formation in the Osgood Mountains and three smaller stocks cut the Harmony Formation in the Hot Springs Range. An age determination of 69 million years was determined for the Osgood Mountains stock, this borders on very Late Cretaceous to Tertiary age. The granodiorite is cut by aplite dikes and small dikes and veinlets of quartz-feldspar pegmatite. Thin tabular bodies of intrusive dacite porphyry are widespread in the Paleozoic sedimentary rocks with possible genetic relationships to the granodiorite (Hotz, P. E., et al., 1964). Remnants of formerly widespread volcanic rocks of Tertiary age, possibly late Miocene, are scattered in the lower parts of the Osgood Mountains and the Hot Springs Range. These are mostly andesitic and some basaltic flow rocks, locally underlain by tuffaceous rocks of rhyolitic composition (Hotz, P. E., et al., 1964) (Figure 5).

Figure 5: Hot Springs Gold Property regional geology.

7.1.1 Structure

The main structural elements strike closely parallel to the northeasterly trend of the ranges. Within both ranges, northwest-striking cross faults are approximately perpendicular to the northeast structures. The rocks in this area are also cut by north-striking high-angle longitudinal faults, which are more continuous and more important structurally than the high-angle cross faults. The north-striking faults trend in the same approximate direction as the northern Nevada rift (Figure 7) (Ponce, et al., 2002) (Hotz, P. E., et al., 1964). 7.1.2 Northern Nevada Rift Zone

The northern Nevada rift zone is comprised of north-northwest trending structures extending in a south-southeast direction for about 500km from the Oregon/Nevada border. The surface trace is marked by an alignment of middle Miocene volcanic rocks and epithermal gold-silver and mercury deposits that formed during west-southwest, east-northeast directional extension. The intrusive mafic rocks were mostly emplaced between 16.5-15Ma and are thought to have resulted from thermal bulging and shallow intrusion of mafic magmas related to the Yellowstone hot spot which at that time had penetrated the upper crust and would have been approximately located near present day McDermitt, Nevada. Magmatism declined as the hot spot migrated to the northeast (John, D.A., et al, 2000). It is thought that the inception of the rift is at 16.5Ma and likely corresponds in part to a pre- Cenozoic deep crustal structure reactivated during the late Cenozoic. There was rapid propagation of the rift to the south, the duration of rifting was short, between 16.5-15Ma. The total amount of extension of the crust along the rift was generally less than a few kilometers. The rift is sub-parallel to the Battle Mountain gold trend and to an older major crustal fault resulting from crustal thinning during Late Proterozoic rifting. Extension created or reactivated linear breaks in the crust, including the structural precursor along the northern Nevada rift that the Battle Mountain gold trend is thought to follow. Hydrothermal activity produced hot springs and epithermal precious metal deposits along the axis of the rift, such as Buckhorn, Fire Creek, and Midas. All epithermal deposits are believed to have formed in the time interval of 15.0-15.6 Ma, some are associated with 15.2-15.86Ma andesite, and ~15Ma rhyolite (John, D.A., et al, 2000).

7.1.3 Gold Trends Associated with Structures

The majority of the gold produced in Nevada is mined from two conspicuous linear alignments of deposits: the Carlin trend and the Battle Mountain-Eureka trend in the central-north and the north-east, both spatially associated with the northern Nevada rift (Figure 6) (Muntean, 2014).

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 This part of Nevada holds one of the largest concentrations of gold in the world (Clark Maroun, L.R., 2016). The Carlin and Battle Mountain-Eureka trends account for 38% and 31% of the 5.6 Moz of gold produced in Nevada in 2012, respectively (Muntean, 2014). Both the Battle Mountain-Eureka gold trend and the Carlin gold trend intersect with the Getchell gold trend in north-central Nevada (Figure 6). These trends result from a regional alignment of major gold deposits thought to represent deeply penetrating, Proterozoic to Paleozoic structures that acted as subsequent zones of weakness, concentrating deformation and channeling mineralizing fluids (Fithian, M.T., 2015) (Groff, J.A., et al., 1997). These gold trends were estimated to have contained more than 200 million ounces of gold before mining began (Cline, J., et al., 2005) (Sillitoe, R., 2008).

The Carlin gold trend is spatially associated with the northern Nevada rift zone and lies to the east of and approximately parallel to the rift zone. It is likely that the eastern structure of the northern Nevada rift extends further over to the east and is represented by the Carlin trend

Brewer, CPG, M.Sc. 3 November 2020 (Sherlock, W.K., 2016). The northern Nevada rift zone hosts the Fire Creek low-sulfidation epithermal deposit with reported bonanza gold grades of over 2,600 g/t Au (85 opt) across 4.8 feet along with 174 opt silver (Davis, D.A., Muntean, J.L., 2012) The Northern Nevada rift zone also hosts the Midas low-sulfidation epithermal deposit with reported bonanza gold grades of over 3,430 g/t Au (100 opt) (Leavitt, E.D., et al, 2004). The author and co-author have not reviewed the grade and intercept estimates reported by Davis, D.A., Muntean, J.L., 2012, and, Leavitt, E.D., et al, 2004, and do not offer an opinion as to their validity and accuracy as part of this Technical Report. The northern Nevada rift generally trends north-south and can be seen to also be spatially associated with the Battle Mountain-Eureka gold trend (Figure 6). As shown in Figure 7, major fault F3 passes through the center of the northern Nevada rift east (NNRE) and the northern Nevada rift west (NNRW)., The Property is located on or adjacent to fault F3 just north of Winnemucca (W). The Midas mine (MI) (Figure 7) is just east of NNRE; however, it has been noted that the eastern structure of the northern Nevada rift could extend over to the Carlin trend (CAR) (Figure 7) (Sherlock, W.K., 2016). The Fire Creek mine is located within the northern Nevada rift. Both the Midas and Fire Creek mines hold significant amounts of gold. It is believed that deeply penetrating structures acted as zones of weakness that concentrated and channeled mineralizing fluids through the northern Nevada rift (Fithian, M.T., 2015) (Groff, J.A., et al., 1997).

Both the Battle Mountain-Eureka gold trend and the Carlin gold trend intersect the Getchell gold trend. The primary ore-controlling structure in the Getchell gold trend is the Getchell Fault Zone, faults along this trend are thought to be linked to underlying basement faults that originated during rifting of western North America during the Proterozoic (Cassinerio, M.D., 2010). The Preble, Pinson, Getchell and Twin Creeks mines occur along this trend and play a large role in defining this trend.

7.2 Property Geology

Available detailed geological mapping is confined to the southern portion of the Property (Figure 10). The majority of the gold mineralization discovered to date on the Property occurs within the Dutch Flats area within a structure known as the Dutch Flats shear zone (Zenda Gold Corp., 1997) (Willden, R., et al., 1955). The Dutch Flats shear zone is located at the intersection of two major gold trends, the Getchell gold trend, and the Battle mountain gold trend (Figure 8 & Figure 9) (Zenda Gold Corp., 1997). Significant amounts of gold, scheelite, and cinnabar are present in

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 placer material, comprised of the Harmony formation, in the Dutch Flats area on the west slope of the southern end of the Hot Springs Range (Willden, R., et al., 1955). This part of the Property is primarily underlain by Cambrian-aged clastic and chemical sedimentary rocks of the Harmony Formation that includes mudstone, shaly siltstone, sandstone, feldspathic greywacke, quartz pebble conglomerate, chert and limestone. The sedimentary rocks generally strike in the same north-easterly direction as the Dutch Flats shear zone and are massively to locally well foliated (sheared) and moderately to locally strongly fractured, the majority of the gold mineralization discovered to date occurs within the Dutch Flats shear zone. The rocks are locally strongly argillized especially within the shear zones. Joints and fractures are commonly filled with veinlets and stringers of quartz and/or calcite. A small quartz monzonite stock of Tertiary age has intruded the sedimentary rocks in the central part of the Property along the Dutch Flats shear zone and covers an area of about 2,000 ft by 1,200 ft (Zenda Gold Corp., 1997), the contact-metamorphic aureole has been observed to extend as far as 500 ft (Willden, R., et al., 1955). The stock is cut by the El Paso Gulch that forms a narrow valley in rocks that are orange, brown in color due to oxidation of pyrite and Fe-bearing mafic minerals. Unaltered outcrops are light grey, medium grained and equigranular. Another similar felsic intrusion occurs in the southwest area of the Property along the Dutch Flats shear zone. The sedimentary rocks adjacent to the intrusion have been locally chemically altered by hydrothermal fluids causing mineral replacement (metasomatized) and have been altered to varying degrees by silicification, argillization and carbonatization. Thin remnants of Tertiary- aged basalt andesite, younger than the intrusive stock, overlie the Harmony Formation as an unconformity, caps the ridges around the Property, and forms a pronounced peak known as Belmont Hill (Zenda Gold Corp., 1997) (Willden, R., et al., 1955).

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 A broad 10,000 foot by 3,400 foot northeasterly-trending (040 degrees) zone of deformation, the Dutch Flats shear zone (Figure 9), cuts across the Property. The zone is characterized by varying degrees of shearing, hydrothermal alteration, and gold mineralization. The previously discussed felsic stocks are found emplaced along this deformation zone and are spatially related with some of the gold mineralization present on the property. Some quartz veining within this zone crosscut the felsic stocks and hence postdate the intrusions. The presence of locally brecciated quartz veins suggests multiple episodes of brittle deformation have occurred. Many quartz veins contain varying anomalous amounts of gold, silver, arsenic, antimony, galena and sphalerite (Zenda Gold Corp., 1997). The quartz veins supplied the gold to the surrounding placer material (Willden, R., et al., 1955). Individual quartz veins within the shear zone vary in width up to 9 feet and can be traced along strike intermittently for several hundred feet, most veins strike parallel with the overall trend of the deformation zone (Zenda Gold Corp., 1997). Brecciated quartz is localized within the shear zone indicating that some of the quartz veining predates shearing (Willden, R., et al., 1955). The quartz veins vary in dip from moderate to steeply dipping towards the northwest in the northwest part of the Property and towards the southeast in the southeast portion of the Property. The majority of the gold mineralization discovered to date occurs within the Dutch Flats shear zone including hydrothermally altered shear structures which suggests a strong structural control for the distribution of gold in the Dutch Flats area (Zenda Gold Corp., 1997). Free gold, galena, sphalerite and cinnabar have been observed in and around the shear zone. The structures of the Dutch Flats zone may be a splay off of the northerly-trending Range Front Fault believed to be located to the southwest of the Dutch Flats area. The Range Front Fault trends parallel with the overall trend of the northern Nevada rift zone (discussed in Regional Geology), the intersection of the Range Front Fault with the Dutch Flats structures represents a viable gold target (Zenda Gold Corp., 1997).

Figure 10: Geological map of the Dutch Flats Mine and El Paso Mine area of the Hot Springs Gold Property (Zenda Gold Corp., 1997).

The known gold mineralization on the Property occurs primarily within the Dutch Flats Fault Zone and is spatially related to northeasterly-trending structures including hydrothermally altered shear zones and associated quartz veins (Zenda Gold Corp., 1997). However, gold mineralization has also been noted associated with the contact zone of the felsic stock as well. OMG has collected a total of 111 surface grab samples from the property which have resulted in significant amounts of Au, Ag, As, Hg and Sb assays. Of the 111 samples collected, 10.8% (12 samples) returned values greater than 1 ppm Au and 49.5% (55 samples) returned values greater than 0.1 ppm Au.

Select samples of quartz collected from veins in the Belmont Shaft area have returned assay values of up to 1.75 opt Au (Duerr 1994). Zenda Gold Corp. (1997) report that 142 grab samples and 35 chip samples were collected from the property in 1997 for Zenda Gold Corp. Although the exact location and sampling methodology is not known to the author, they report that 47 samples returned values greater than 100 ppb Au (0.003 opt Au) and 8 samples returned values greater than 1,000 ppb Au (0.03 opt Au). They report one select grab sample that returned a value of 7,079 ppb Au (0.21 opt Au) from the El Paso area and two 8-foot chip samples that returned values of 1,112 ppb (0.03 opt Au) and 1,590 ppb (0.05 opt Au) from the Canyon and El Paso areas respectively.

The widespread significant gold mineralization and high As, Ag and Sb values suggest that the Property may be host to the surface expression of the upper area of a low-sulphidation epithermal gold system (Figure 11 & Figure 12). “Gold appears in the placer material as nuggets, course angular grains, sometimes attached to a quartz matrix, and as fine angular free grains, the maximum distance of transport is less than 2 miles. It is unlikely, however, that the gold particles would decrease very much in grain size in such a short distance” (Willden, R., et al., 1955). Gold is also found in north-east trending quartz veins trending along with the major north-easterly trending zone of multiple faults and shearing (Zenda Gold Corp., 1997). The El Paso Gold Mine was developed on the lode gold quartz veins near the contact area of the felsic quartz monzonite stock (Willden, R., et al., 1955). Cinnabar, a common vein-filling material, is found within and around the shear zone with grain sizes ranging from dust to 1cm diameter nuggets and shows a closer correlation of grain size with distance of transport versus gold, larger grains are found in the upper part of the El Paso Gulch. The Dutch Flats mercury mine was developed on the shear-zone hosted cinnabar showings (Willden, R., et al., 1955).

8 Deposit Types

The Property hosts gold and silver-bearing mineralization with metallogenic characteristics commonly associated with a low-sulphidation epithermal mineralizing system. Epithermal deposits are defined as deposits that occur at shallow depths within 1-2km of the surficial hot springs settings at low temperatures (<300C) where the gold-silver mineralization is emplaced into pre-existing structures (Figure 11), ultimately expressed as quartz veins, veining- stockworks, and silicified breccias that can contain the mineralization at varying amounts (Corbett, C., Leach, T., 1997) (Panteleyev A., 1996). Andesitic volcanic rocks are the most common host rocks, usually in areas of volcanism and subaerial ash flow deposits. Epithermal systems can be of any age, are commonly related to their host volcanic rocks, and are invariably slightly younger (approximately 0.5 to 1Ma) than the host volcanic rocks (Sillitoe, R.H., 1993). Large scale regional deeply penetrating structures (faults) focus the flow of mineralized fluids and provide the structural controls that lead to the deposition of gold and silver. Commonly associated regional tectonic settings for epithermal systems are along mid-ocean ridges, subduction zones, continental rift zones, volcanic arcs along inter-oceanic subduction zones, and continental volcanic fields with extensional structures. The regional scale fracture systems are structural controls related to grabens, resurgent calderas, and flow-dome complexes.

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 Extensional or dilational features such as jogs, flexure, fault splays, normal faults, sheeted fractures, and breccias promote high rates of fluid flow to allow for bonanza gold grades (>1opt gold) to deposit (Leavitt, E.D., et al, 2004). Fissure (dilational) vein subsidiary structures form from the broader regional structures at depths in the range of 300 – 400 m below the paleosurface but may locally extend to much deeper crustal levels. In the upper levels of fissures where confining pressures become reduced, fluids may mushroom laterally out from the fissures to form stockwork fractures above the fissure veins. The stockwork veins typically predominate at depths of 100 – 400 m below the paleosurface and mainly occur as steeply dipping sheeted veins extending from the deeper dilationaly larger fissures (Leavitt, E.D., et al, 2004) (Buchanan, L.J., 1981) (John, D.A., et al., 2018). Low-sulphidation epithermal deposits form in subaerial volcanic fields, commonly felsic, in extensional and strike-slip (shearing) regimes, and also form in island arc or continental andesitic stratovolcanoes above active subduction zones. Structure and permeable rocks provide the controls to allow for the near-surface hydrothermal fluid flow to migrate (Panteleyev A., 1996). Driving the deep circulating hydrothermal fluids in the geothermal system is the heat source which is considered to be deeply buried (>5-6 km from the surface). The heat source could be a granite/granodiorite formed from melted continental crust; it could also be a porphyry intrusion in association with subduction zones; generally, however the heat source is of some composition of a magmatic intrusion (Leavitt, E.D., et al, 2004) (Buchanan, L.J., 1981) (John, D.A., et al., 2018). In low sulfidation systems, the upwelling hydrothermal magmatic fluids contain dissolved magmatic volatiles exsolved from cooling magma intrusions. The magmatic fluids become diffused within large circulating hydrothermal systems to considerable depths along regional and subsidiary structures. Sinter deposits develop from the venting at surface of outflowing hydrothermal fluids that deposit silica from the cooling fluids. Sinters are commonly localized by eruption breccias (vents) which may overlie fluid up-flows from fissure veins, many sinters are subjacent to gold-bearing fissure veins (Leavitt, E.D., et al, 2004). Deposition of precious metals occurs from the mixing of descending cool oxidizing meteoric waters with ascending hot circulating mineralized hydrothermal fluids from deep magmatic sources. An indicator of a magmatic component for the mineralizing fluids is the presence of telluride minerals. The mixing of these two fluids gives way to pressure and temperature changes to produce a vertically and horizontally zoned epithermal system in the rocks of As, Hg, Sb, W, Tl, Pb, Zn, Au, and Ag. (Figure 11)The oxidizing effect from the mixing fluids will also allow for the in-place deposition of hematite (hypogene hematite) in the vertical and horizontal zones, a diagnostic feature of the mixing of the fluids. This location of the vertical and horizontal zones resulting from the mixing fluids is termed the “boiling-zone”. Deposition of the metals is in response to reduced pressure and temperature as a result of quenching of the circulating fluids. The cool meteoric waters mixing with the hot mineralized hydrothermal fluids causes a decrease in temperature and from that a decrease in pressure that results in the act of boiling (Leavitt, E.D., et al, 2004) (John, D.A., et al., 2018) (Sillitoe, R.H., 1993) (Panteleyev A., 1996). The

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 vertically zoned part of the epithermal system commonly yields a gold- and silver-rich, base metal-poor top, grading to a relatively silver-rich and base metal-rich zone at depth, then grading further into a sparse base metal, pyritic zone (Figure 11) (Buchanan, L.J., 1981) (Sillitoe, R.H., 1993) (Panteleyev A., 1996). The boiling-zone in low sulphidation epithermal deposits are commonly characterized by bonanza metal grades exceeding 30 g/t gold (>1opt gold), including elevated silver contents (Corbett, C., Leach, T., 1997). The Fire Creek low-sulfidation epithermal deposit located in north- central Nevada reported bonanza gold grades of over 2,600 g/t Au (85 opt) across 4.8 feet along with 174 opt silver (Davis, D.A., Muntean, J.L., 2012). The Fire Creek deposit reports a proven resource grading at 41.5 g/t Au (Form 8 – K Hecla Mining Co., 2019). The Midas low-sulfidation epithermal deposit located in north-central Nevada also reported local bonanza gold grades of over 3,430 g/t Au (100 opt) (Leavitt, E.D., et al, 2004). Epithermal gold deposits are characterized by bonanza grades and are among the richest gold deposits in the world. Silver mineralization mimics base metal phases at deeper levels of hydrothermal systems, and gold at shallower levels. However, where there are structurally dilational features such as flexures, jogs and vein intersections then higher-grade ore shoots can be expected. Low sulphidation systems commonly contain minerals such as sphalerite, galena, chalcopyrite, silver and native silver. The mixing (boiling) of the fluids in low sulphidation gold deposits reveals a close association of hypogene hematite and gold mineralization. Hypogene hematite is indicative of oxidizing environments and is thought to be a significant mechanism for gold deposition and formation of bonanza gold deposits (Leavitt, E.D., et al, 2004) (Clarke, D.S., 1989) (John, D.A., et al., 2018). The hypogene process can extend deep below the earth’s surface from natural physical mechanisms thereby extending the mineralization at depth. Sinter deposits form from fluid outflows on to the surface through a dilated structural feature. If sealed caps form episodically then a pressure on the system that exceeds hydrostatic pressure will develop. When the cap is fractured and the excess pressure is released, the solutions will boil at a greater depth and allow for a greater vertical ore interval (Leavitt, E.D., et al, 2004) (Buchanan, L.J., 1981). The presence of high-level intrusions may promote the development of phreatomagmatic breccias. The eruption breccias result from mixing of cool waters with hot fluids in the shallow crust. The flashing (sudden pressure release) of deep hydrothermal fluids to atmospheric pressure can deposit high concentrations of gold and silver. Indicative of phreatomagmatic breccias are banded fissure vein ores which result from the periodic, structurally controlled pressure release (Leavitt, E.D., et al, 2004) (Buchanan, L.J., 1981). Geophysical surveys commonly indicate this feature as a roughly circular tube extending to depth often described as a pipe-like feature. Sinter and (hydrothermal) eruption breccia systems are indicative of environments conducive to the identification of buried fissure vein hosted gold mineralization (Buchanan, L.J., 1981). Anomalous As, Hg, Sb, W, Tl, Pb, Zn, Au, and Ag are recognized in proximal settings to eruption breccia vents, whereas sinter deposits further from the vent tend to be

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 barren. Some of the best gold grades are located closest to the eruption breccia (Leavitt, E.D., et al, 2004) (Buchanan, L.J., 1981).

9.1 OMG 2020 Soil Sampling Program

OMG hired Brewer Exploration Inc. of Salmon, Idaho to collect 60 stream sediment samples from the Property in May 2020. These samples were collected from locations throughout the Property. Samples were screened to approximately 0.5 kg passing 150µm at each sample location. Samples were analyzed for Au and multi elements by ALS labs in Reno, Nevada utilizing aqua regia extraction with ICP-MS finish. High values for select elements include 0.048 ppm Au, 0.74 ppm Ag, 106 ppm As, 0.28 ppm Hg and 2.81 ppm Sb. Sample locations and results for several select elements are shown in the following figures (Figures 13, 14, 15 & 16).

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020

Stream sediment sampling programs are commonly utilized to cover a large area with a limited number of samples. The sample locations are picked in an attempt to indicate anomalies associated with geological features contained within a certain drainage or catch basin represented by the sample. The size of the area represented by each sample is dependent upon the geographical features contained within that area.

The wide-spread anomalous As, Sb and Hg values may be the surface expression of the upper level of a low-sulphidation epithermal gold-silver deposit as shown in Figure 13. Follow-up exploration of these anomalies is warranted to further understand the relationships between the anomalies and potential structures such as faults, veins and breccia pipes.

The geologic settings of the Getchell and Turquoise Ridge gold deposits are of particular relevance to the Property. Gold mineralization in both the Getchell and Turquoise Ridge deposits is closely spatially associated with the east- to northeast-dipping Getchell structural zone. In the case of Turquoise Ridge, the deposit is situated in the hanging wall. Cassinerio and Muntean (2011) have presented evidence that the mineralizing hydrothermal fluids were channeled by the Getchell fault to hanging-wall faults and fracture networks that were important controls on the gold deposit formation. The author and co-author have not been able to verify the information of Cassinerio and Muntean (2011), and it is not necessarily indicative of mineralization on the Property that is the subject of this Technical Report.

25 Interpretation and Conclusions

The Property is located in the Getchell gold trend at the intersection with the Battle Mountain gold trend in north-central Nevada. The Property has had sporadic exploration efforts but appears to have lacked a concerted systematic exploration program conducted on it.

While the bulk of the known Au mineralization occurs within the Dutch Flats Fault Zone, potential exists for other targets outside of this zone. Most notably, the anomalous area identified by soil

Brewer, CPG, M.Sc. 3 November 2020 samples to the east, and parallel to, the Dutch Flats Fault Zone and the hypothesized juncture of the Dutch Flats Fault Zone and the Range Front Fault to the west.

The author and co-author are not aware of any environmental, permitting, legal, title, taxation, socio-economic, political or any other relevant factors that could materially prevent the Hot Springs Property from being a property of merit.

26 Recommendations

The Property is a property of merit and it is recommended that Frontera continue exploration and development of the Property. It is recommended to test the extent of mineralization in areas that have been identified by previous operators, and to carry out a systematic exploration program to identify new areas of mineralization. Next steps should include multi-phase drill programs systematically commingled with geophysical surveys in two (2) phases, as follows:

Phase 1:

1 Conduct a property-wide geological mapping and sampling program to better understand the mineralization and to identify additional target areas; 2 Conduct a property-scale soil sampling program on a 100m by 200m grid (100m sample spacing on grid lines spaced 200m apart); 3 Develop a digital 3-dimensional definition of the location and orientation of the structures that control and contain the mineralization. The digital model will be built from data collected from exploration results from historical drilling, and further developed from exploration results from new drilling. The historical exploration and drilling results are available in digital format; 4 Test the reproducibility of the portion of the historic drill holes that intersected mineralized structures within the target areas encompassing the El Paso mine, Belmont Shaft, North Belmont, Canyon area, and Dutch Flats mine that are all located within the Dutch Flats shear zone. Work performed in 1997 revealed these areas as prospective targets to be pursued. Six historical drill holes are recommended for twinning with new drill holes. The target historic holes are A-13 to a length of 400 feet, B-16 to a length of 300 feet, B-18 to a length of 300 feet, B-21 to a length of 300 feet, DF-14 to a length of 150 feet, and DF-32 to a length of 400 feet; 5 Utilize geophysics and drilling to define the location and orientation of the structures feeding the mineralization. The recommended geophysical method is Induced Polarization, Magnetic Susceptibility, and Controlled-source Audio-frequency Magnetotellurics (CSAMT) surveys. Investigate vertical extension of historically drill-hole identified mineralized structures to depth to explore for higher grade zones of mineralization. This would be accomplished from interpreted geophysical data, mentioned in point 3, deriving targets from the interpreted geophysical data, and testing those targets with drill holes. Any proposed drilling would be contingent on the results of the geophysical survey results (see phase 2);

NI 43-101 Technical Report Frontera Gold Inc. and Wolf Acquisition Corp. Hot Springs Gold Project, Humboldt County, Nevada Vancouver, BC, Canada Brian T. Brewer, CPG, M.Sc. 3 November 2020 6 Investigate a likely structural intersection target; the NE-SW trending Dutch Flats shear zone intersecting with the north trending Range Front Fault. The Range Front Fault trends in the same direction as the northern Nevada rift zone and is within the same rift zone. The investigation would be accomplished from interpreted geophysical data, mentioned in point 3, deriving targets from the interpreted geophysical data, and testing those targets with drill holes. Any proposed drilling would be contingent on the results of the geophysical survey results (see phase 2); 7 Utilize larger diameter core drilling (i.e., HQ) to identify ore characteristics and gold distribution characteristics through screen fire assay, and metallurgical testing.

Phase 2:

Phase 2 is contingent on positive results from Phase 1.

8 Proposed 6 drill hole program, approximating 2,000 meters in total, contingent on geophysical results from investigating the vertical extension of mineralized structures (see point 3). Drill hole lengths depend on results from the geophysical survey; 9 Proposed 6 drill hole program, approximating 2,000 meters in total, contingent on geophysical results from investigating the likely structural intersection of the Dutch Flats shear zone with the northern trending Range Front Fault (see point 4). Drill hole lengths depend on results from the geophysical survey; 10 Investigate a wide linear target parallel to and 300m east of the Dutch Flats shear zone as a possible ore feeding structure as identified through work performed in 1997. The investigation would be accomplished from interpreted geophysical data, mentioned in point 3, deriving targets from the interpreted geophysical data, and testing those targets with drill holes. Any proposed drilling would be contingent on the results of the geophysical survey results, the proposed drilling would take place in a future phase; and 11 Expand NE and SW along the Dutch Flats shear zone. The investigation would be accomplished from interpreted geophysical data, mentioned in point 3, deriving targets from the interpreted geophysical data, and testing those targets with drill holes. Any proposed drilling would be contingent on the results of the geophysical survey results and would occur in a future phase.
