Mill throughput at 857 kt (Q4 June FY19: 780 kt) was the best result since Q1 September FY19. • All-in Sustaining Cost has increased as a result of lower production. • Works to replace the scrubber and install a new pebble crusher are expected to be completed in Q2 December FY20. The impact of this work on production is not anticipated to be material. The pebble crusher will better equip the SAG mill for treatment of harder rock, leading to increased throughput, while replacement of the scrubber will reduce downtime on

Atlantic Gold growth projects

• There are three further Atlantic Gold projects scheduled for permitting and development : Beaver Dam, Fifteen Mile Stream and Cochrane Hill. • Beaver Dam: planned to have minimal site infrastructure, with ore trucked approximately 30 kilometres to the Touquoy processing plant. The Federal Environmental Impact Study was submitted in March 2019. • Fifteen Mile Stream: development plan is for a processing plant involving comminution, gravity gold extraction and concentration, with the concentrate trucked approximately 80 kilometres to the Touquoy processing plant. The Federal Environmental Impact Study was submitted in October 2019. • Cochrane Hill: development plan is for a processing plant involving comminution, gravity gold extraction and concentration, with the concentrate trucked approximately 155 kilometres to the Touquoy processing plant. The Federal EIS is planned to be submitted in late 2020. • As these projects are permitted and brought into production, gold production at Atlantic is anticipated to exceed 200,000 ounces per annum whilst maintaining its low cost profile.

Gwalia Deeps Drilling - Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.)

Criteria Commentary Sampling techniques • Half-core sampling of NQ2 diamond drilling with boundaries defined geologically. Samples are mostly one metre in length unless a significant geological feature warrants a change from this standard unit. The upper or right-hand side of the core is submitted for sample analysis, with each one metre of half core providing between 2.5 – 3 kg of material as an assay sample. Drilling techniques • Diamond drilling using NQ2 (50.6mm) sized core (standard tubes). Holes have been surveyed using a north seeking multishot electronic camera. All core is orientated using a Reflex ACT III RD orientation tool. Drill sample recovery • Core is metre marked and orientated and checked against drillers blocks to ensure that any core loss is accounted for. • Sample recovery is rarely less than 100%. Where minor core loss does occur it is due to drilling conditions and not ground conditions. Logging • All SBM holes are logged primarily for lithology, alteration and vein type/intensity which are key to modelling gold grade distributions. Validation of geological data is controlled via the use of library codes and reliability and consistency of data is monitored through regular peer review. • All logging is qualitative. Sub-sampling • SBM half core is cut using a core saw before being sent to SGS laboratory in Kalgoorlie where the entire sample is crushed techniques and to achieve particle size <4mm followed by complete pulverisation (90% passing 75 µm). sample preparation Quality of assay data • SBM samples were analysed for gold using fire assay with a 50g charge and analysis by flame Atomic Absorption(FAA505) and laboratory tests Spectrometry (AAS). QC includes insertion of 3 commercial standards (1 per 20 samples), barren material used for blank control samples, use of barren flush material between designated high grade samples during the pulverising stage, re- numbered sample pulp residues re-submitted to original laboratory, and sample pulp residues submitted to accredited umpire laboratory, submission of residual (duplicate) half core from ore intervals. The analysis of gold was sound and re- analysis of pulps showed acceptable repeatability with no significant bias. Verification of • Sampling data is recorded electronically in spread sheets which ensure only valid non-overlapping data can be recorded. sampling and Assay and down hole survey data are subsequently merged electronically.

Drilling - Section 1 Sampling Techniques and Data (Criteria in this section apply to the succeeding section.)

Criteria Commentary Sampling techniques • Sampling was conducted via Aircore and RC drilling. Aircore drill holes were on 50 m or 100 m spacing with line spacing ranging between 200 m and 1,600 m or as individual scout lines. RC holes were not designed on any regular spacing. • Samples were collected from a rig-mounted cyclone by bucket and were then placed directly on the ground in neat rows of between ten and fifty (depending on hole depth). • Drill spoil was sampled with a scoop to 4 m composite samples of approximately 2.5 kg. • During RC drilling one metre samples were also generated by the rigs cone splitter system and collected in calico bags, these were left on the ground on top of the corresponding metre of drill spoil. One metre samples are submitted for assaying based on the results of the initial 4m composite sampling. • The Aircore composites were submitted to Bureau Veritas Minerals Pty Ltd - Perth where they were sorted and dried, crushed to 10 mm and pulverised to -75 µm. A 40 g charge of pulverised sample was then digested with aqua regia with a gold analysis by ICP-MS to a detection limit of 1 ppb. The same digested sample was also tested for arsenic by ICP-AES to 1ppm detection limit. • Anomalous Aircore composite samples (>100ppb Au) were subsampled on a metre by metre basis using an aluminium scoop. These samples were submitted to Bureau Veritas Minerals Pty Ltd- Perth where they were sorted and dried, crushed to 10mm and pulverised to -75 μm. A 40 g charge of pulverised sample was then analysed for Au, Pd & Pt by Fire Assay with an ICP-AES finish to a detection limit of 1ppb. • Anomalous RC composite samples (>100 ppb) were subsampled using the previously collected one metre samples from the rigs cone splitter system. These were submitted to Bureau Veritas Minerals Pty Ltd - Perth where they were sorted, dried, crushed to 10 mm and pulverised to -75 µm. A 40 g charge of pulverised sample was then analysed for Au by Fire Assay with an ICP-AES finish to a detection limit of 1 ppb. • Representative specimens from end of hole Aircore rock chips were stored in plastic chip trays for future reference. For RC drilling a representative specimen of every metre was stored in plastic chip trays for future reference. • The EOH Aircore samples, as well as a selection of RC samples, were submitted to Genalysis and were prepared in the same manner as those samples submitted to Bureau Veritas. A 10g charge of pulverised sample was then digested by four acid digestion with analysis by the Scott Halley technique (ICP-OES & ICP-MS to ultra-trace levels) via 4A/OM20 method for 60 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Ho, Ln, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pr, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn & Zr). Drilling techniques • Aircore drilling was carried out by an 85 mm bit. All holes were drilled to refusal, which was generally at the fresh rock interface.

Drilling - Section 1 Sampling Techniques and Data (Criteria in this section apply to the succeeding section.)

Criteria Commentary Sampling techniques • Diamond Drilling - Sampled using PQ3 (85mm), HQ3 (61.1mm) and NQ3 (45mm) sized core using standard triple tubes. Half or quarter core was sampled on nominal 1 or 2-metre intervals with the upper or left - hand side of the core collected for sample preparation. For PQ diameter core a further cut was completed, whereby quarter core is submitted to provide a practical sample size. • Half core or quarter core was dispatched to the ITS PNG Ltd (Lae) sample preparation facility with 250g pulps sent to Intertek Laboratory in Perth. Pulps residuals are stored in (Lae) for six months following assay. • RC Drilling at Sorowar - One metre samples were generated by the rigs cyclone splitter system by collection in calico bags. When samples are wet, samples are collected in a 20 litre bucket, the water decanted and the sample transferred to the calico bag. One metre calico bag samples are then submitted for assay. Samples were fully prepared at the company's on-site sample preparation facility on Simberi Island with 200g pulps sent to SGS Laboratory in Townsville. Pulp residues are stored in Townsville for future re-assay if required. Drilling techniques • Diamond drilling comprised PQ3 (85mm), HQ3 (61.1mm) and NQ3 (45mm) core recovered using 1.5m to 3m barrels. Drilling was completed by Quest Exploration Drilling (QED). When ground conditions permit, an ACT Digital Core Orientation Instrument was used by the contractor to orientate the core. • RC drilling at Sorowar was carried out using 140mm hammer bits. Drilling was completed by Quest Exploration Drilling (QED) who utilised a track mounted SCHRAMM 685 rig coupled to an auxiliary compressor/booster unit. A limited number of holes were drilled using a DML 45 drill, also coupled to the auxiliary compressor/booster unit. Drill sample recovery • Diamond drilling recovery percentages were measured by comparing actual metres recovered per drill run versus metres measured on the core blocks. Recoveries averaged over >90% with increased core loss present in fault zones and zones of strong alteration. • RC drilling conditions (wet/dry) were routinely recorded. The drill cyclone and sample buckets were cleaned regularly, in particular after wet ground was encountered, nominally after each six metre rod, depending on ground conditions. The cyclone was also cleaned several times during the course of each hole and after the completion of each hole. Logging • Diamond holes are qualitatively geologically logged for lithology, structure and alteration and qualitatively and quantitatively logged for veining and sulphides. Diamond holes are geotechnically logged with the following attributes qualitatively recorded - strength, infill material, weathering and shape. Whole core together with half core, were photographed when dry and wet. • RC drilling chips were sieved, cleaned, logged and photographed. Reference material was not stored in plastic chip trays for future reference. • All holes are fully logged. Sub-sampling techniques • All diamond drill core associated with St Barbara work program was half cut with the upper or left-hand side and sample preparation submitted for assay. For PQ diameter core a further cut was completed, whereby quarter core is submitted to provide a practical sample size. All samples were sent to ITS PNG Ltd (Lae) sample preparation facility, where preparation involves drying, jaw crush to 95% passing -4.75mm, pulverise in LM5 or LM2 to a minimum 95% passing -106um, with 250g pulps sent to Intertek Laboratory in Perth. Pulps residuals are stored in Lae for six months following assay. Quality control of sub-sampling consisted of insertion of blank control samples and coarse reject duplicates, both at a ratio of 1:20 samples. • All Sorowar reverse circulation rock chip and diamond core samples were fully prepared at the company's on-site sample preparation facility on Simberi Island. Preparation involved drying, jaw crush to 70% passing -6mm, pulverise in LM5 or LM2 to a minimum 85% passing -75um, with 200g pulps sent to SGS Laboratory in Townsville.

Criteria Commentary Quality of assay data and • All diamond drill samples associated with the St Barbara work program (excluding the Sorowar RC and Diamond laboratory tests drill samples) were sent to Intertek for analysis. Half or quarter core samples were analysed for Au via 50g Fire Assay ICP and AAS finish (FA50/ICP OE04 method) for low detection sample or 50g Fire Assay and AAS finish (FA50/AA method) and then multi-elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl, U, V, W, Y, Zn and Zr) via 4 acid digest with HF (4A method) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) or Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) via (OM10 method). QC included insertion of certified reference material (1 in 20); insertion of in-house blank control material (1 in 20); and the insertion of reject residues (1 in 20). QAQC results were assessed as each laboratory batch was received and again on a quarterly basis. Results indicate that pulveriser bowls were adequately cleaned between samples. • All Sorowar Reverse Circulation rock chips and diamond core were analysed for gold using fire assay with a 50g charge and analysis by flame atomic absorption spectrometry (FAA505 method) at SGS, Townsville; and then multi-elements (Ag, As, Ca, Cu, Mo, Pb, S, Sb, Zn) via 4 acid digest (DIG41Q method) and Inductively Coupled Plasma Atomic Emission Spectroscopy ICP-AES via (ICP41Q method). • Diamond drilling QC included insertion of certified reference material (1 in 20); insertion of in-house blank control material (1 in 20); and the insertion of reject residues (1 in 20). QAQC results were assessed as each laboratory batch was received and again on a quarterly basis. Results indicate that pulveriser bowls were adequately cleaned between samples. Sorowar Reverse Circulation drilling QC included insertion of certified reference material (1 in 20); insertion of in-house blank control material (between 1 in 15 and 1 in 20). • Intertek Perth and SGS Townsville inserted certified standards and replicates and lab repeats. Verification of sampling • Sampling data is recorded electronically which ensures only valid non-overlapping data can be recorded. Assay and and assaying downhole survey data are subsequently merged electronically. All drill data is stored in a SQL database on secure company server. No twin holes have been completed. Location of data points • All Simberi Island collars were surveyed by in-house surveyors using DGPS using Tabar Island Grid (TIG) which is based on WGS84 ellipsoid and is GPS compatible. Tatau and Tabar Island collars were surveyed initially by hand held GPS and by DGPS after hole completion. All holes were downhole surveyed using either a Reflex or Ranger single shot camera with the first reading at about 18m and then approximately every 30m increments to the bottom-of-the hole. • For Sorowar Reverse Circulation drilling, one survey reading was collected at the bottom of the hole and a second at approximately half the hole’s maximum depth. Data spacing and • Diamond drilling data is not yet sufficient to establish continuity of the lodes and therefore the drill spacing is distribution irregular and broad spaced. • At Sorowar pit, the RC drilling data is sufficient to establish continuity of the lodes in some areas of the Sorowar pit, with infill holes on a nominal 30m x 30m having been drilled. Elsewhere, in the Sorowar area, the drilling density is nominally at a 60m x 60m spacing, and still insufficient to be able to predict orebody continuity. Orientation of data in • Where surface mapping and sampling has contributed to understanding of outcropping geological structures, relation to geological drilling and sampling has been undertaken orthogonal to the mapped structure. structure • At Sorowar pit, the RC drilling targeting sulphide gold mineralisation is optimised with holes drilled at 60° dip towards the northeast where possible to test the interpreted main northwest striking orientation to mineralisation. Limited RC holes are drilled in a vertical or 60° dip towards the southwest orientations when access is restricted. Sample security • Only company personnel or approved contractors are allowed on drill sites; drill core is only removed from drill site to secure core logging/processing facility within the gated exploration core yard; core is promptly logged, cut and prepped on site. The samples sent to Intertek are stored in locked and guarded storage facilities until receipted at the Laboratory. Audits or reviews • No audits or reviews of sampling protocols have been completed.

Nord Pacific followed by Allied Gold was instrumental in the discovery and delineation of the 5 main oxide and sulphide deposits at Simberi. Geology • The Simberi gold deposits are low sulphidation, intrusion related adularia-sericite epithermal gold deposits. The dominant host rocks for mineralisation are andesites, volcaniclastics and lesser porphyries. Gold mineralisation is generally associated with sulphides or iron oxides occurring within a variety of fractures, such as simple fracture in- fills, single vein coatings and crackle brecciation in the more competent andesite units, along andesite/polymict breccia contact margins as well as sulphide disseminations. • On Tatau and Big Tabar Islands, located immediately south of Simberi, porphyry Cu-Au, epithermal quartz Au-Ag and carbonate-base metal Au mineralisation is present. • On Simberi Island, Diamond and RC drilling is being conducted on the Simberi ML136 testing for epithermal sulphide gold potential. • Diamond drilling is being conducted at Simberi Island on the Simberi ML136 at depth below Pigiput pit and on Big Tabar Island at Banesa Prospect testing for porphyry Cu-Au mineralisation. Drill hole Information • Drill hole information is included in intercept table outlining collar position obtained by DGPS pickup, hole dip and azimuth acquired from a downhole surveying camera as discussed in section 1, composited mineralised intercepts lengths and depth as well as hole depth. Data aggregation • For gold only epithermal mineralisation, broad down hole intercepts are reported as length weighted averages using methods a cut-off of 0.5 g/t Au and a minimum grade*length of 5gmpt. Such intercepts may include material below cut-off but no more than 5 sequential metres of such material and except where the average drops below the cut-off. Supplementary cut-offs, of 2.5g/t Au, 5.0g/t Au and 10g/t Au, may be used to highlight higher grade zones and spikes within the broader aggregated interval. Single assays intervals are reported only where ≥5.0g/t Au and ≥1m down hole. • For porphyry copper-gold mineralisation at Banesa, broad downhole intercepts are reported as length weighted averages using a cut-off of 0.1 g/t Au and a minimum length of 20m with up to 10m of sequential internal dilution. Supplementary cut-offs of > 0.5 g/t Au may be reported. Au and Cu grades are reported. • For both mineralised styles, core loss is assigned the same grade as the sample grade; no high grade cut is applied; grades are reported to two significant figures and no metal equivalent values are used for reporting exploration results. Relationship between • Down hole length is reported for all holes; true width is not known as the orientation of the orebody is not fully mineralisation widths understood. and intercept lengths Diagrams • Diagrams show all drill holes material and immaterial to Exploration Results.

Drilling - Section 1 Sampling Techniques and Data (Criteria in this section apply to the succeeding section.)

Criteria Commentary Sampling techniques • Drill holes were sampled in their entirety, in nominal meter intervals. • Core samples have been processed as sawn to half core using a diamond-tipped core saw with nominal 1m half-core sample intervals. Samples were dispatched from Atlantic’s core facility in Moose River, directly to ALS in Sudbury, ON or in some cases ALS in Moncton, NB. Drilling techniques • Diamond drilling comprised NQ core recovered using 3m barrels. Drilling was completed by Maritime Diamond Drilling (MDD) and Major Drilling. Drill sample recovery • Diamond drilling recovery percentages were measured by comparing actual meters recovered per drill run versus meters measured on the core blocks. Recoveries averaged over >90% with increased core loss present in fault zones and zones of strong alteration. Logging • Diamond holes are qualitatively geologically logged for lithology, structure and alteration and qualitatively and quantitatively logged for veining and sulphides. Whole core was photographed when dry and wet. Core recovery and rock quality designation (RQD) were measured for each hole at the same metre-by-metre intervals. • All holes are fully logged. Sub-sampling techniques • Sawn half-core samples were submitted to ALS Chemex facility where each sample was dried, finely crushed to and sample preparation better than 70% passing a 2mm screen. A split up to 1,000g was taken using a Boyd rotary splitter and pulverized to better than 85% passing a 75µm screen. Quality of assay data and • A subsample of 50g was analysed by ALS Vancouver via 50g Fire Assay with AAS finish (ALS method Au-AA26). laboratory tests • Diamond drilling QC included randomized insertion of four OREAS certified reference materials (1 in 28) and insertion of in-house blank control material (1 in 28). QAQC results were assessed monthly. Results indicate good quality in laboratory sample preparation and analysis procedures. • Pulverized duplicates were prepared and analysed on every tenth original sample. • ALS inserted certified standards, blanks and lab repeats. Verification of sampling • Sampling data is recorded electronically which ensures only valid non-overlapping data can be recorded. Assay and and assaying downhole survey data are subsequently merged electronically. All drill data is stored in an SQL database on secure company server. Location of data points • All drill collars were surveyed by both third party (WSP) and in-house surveyors using DGPS. Drill collars were surveyed initially by handheld GPS and by DGPS after hole completion. All holes were downhole surveyed using either a Reflex EZ-Trac or Reflex EZ-Gyro at least 6m below casing and 30m increments to the bottom-of-the hole. Data spacing and • For Beaver Dam area (Mill Shaft, Cameron Flowage and Crusher Lake), Seloam’s Brook and Bear Brook diamond distribution drilling data is not yet sufficient to establish continuity of the mineralization and therefore the drill spacing is irregular and broad spaced. • In Cochrane Hill and Fifteen Mile Stream, diamond drilling data is generally spaced on a 25m X 20m grid. Orientation of data in • Where surface mapping and sampling has contributed to understanding of outcropping geological structures, relation to geological drilling and sampling has been undertaken perpendicular (orthogonal where possible as near vertical/steeply structure dipping ore bodies makes this difficult) to the mapped structure. Sample security • Only company personnel or approved contractors are allowed on drill sites; drill core is only removed from drill site to secure work site trailer; core is promptly logged and shipped to Moose River core Facility, where it is cut and prepped. The samples sent to ALS are stored in locked and guarded storage facilities until receipted at the Laboratory. Audits or reviews • No audits or reviews of sampling protocols have been completed.

Criteria Commentary Mineral tenement and • AGB has 100% ownership of the tenements over the Cochrane Hill deposit (EL51477); Seloam’s Brook Prospect land tenure status (EL05889, EL51573 and EL 52901) and Beaver Dam Area (EL50421). Exploration done by • Massval Mine, Northumberland Mines, Scominex, NovaGold, Acadian, Pan East, Seabright, MRRI, Aurogin, other parties Scorpio have all previously worked in the areas reported in this section. Geology • The Atlantic Gold gold deposits are mesothermal gold deposits hosted in folded turbidite sequences of the Meguma supergroup. The dominant host rocks for mineralisation are the argillites, with lesser greywackes (associated with shear zones). Gold mineralisation is generally associated with shearing, quartz veining and minor sulphides, but exists as free gold, and is found disseminated throughout the host rock as well as higher grade quartz veins. Drill hole Information • Drill hole information is included in intercept table outlining collar position obtained by DGPS pickup,(or in some cases listed as original handheld GPS layout if they haven’t been picked up by DGPS survey at time of report), hole dip and azimuth, composited mineralised intercepts lengths and depth as well as hole depth. Data aggregation • For Cochrane Hill and Fifteen Mile Stream Deposits (including Seloam’s Brook Prospect), broad down hole intercepts methods are reported as length weighted averages using a cut-off of 0.5 g/t Au and a minimum grade*length of 3gmpt. Such intercepts may include material below cut-off but no more than 3 sequential meters of such material and except where the average drops below the cut-off. Single assay intervals are reported only where ≥3.0g/t Au. • For Beaver Dam area (Cameron Flowage, Mill Shaft, and Crusher Lake), broad down hole intercepts are reported as length weighted averages using a cut-off of 0.5g/t Au and a minimum grade*length of 0.5gmpt. Such intercepts may include material below cut-off but no more than 1 sequential meters of such material and except where the average drops below the cut-off. Single assays intervals are reported only where ≥3.0g/t Au. Relationship between • For Cochrane Hill, down hole length is reported for all holes. Holes drilled were inclined to the south (azimuth 171°) mineralisation widths at angles between 69° and 49° from horizontal. Mineralisation is confined to a tabular zone or envelope that dips to and intercept lengths the north at approximately 70° such that drill holes intersect the mineralization at angles of between 41° and 61° respectively and down-hole mineralized intercepts are exaggerated over true widths by between 1.1 and two times. • For Fifteen Mile Stream, down hole length is reported for all holes. Holes drilled were inclined to the south (azimuth 175°) at 45° from horizontal, true width is not known as the orientation of the orebody is not fully understood. • For Beaver Dam area, down hole length is reported for all holes. Holes drilled were inclined to the south (azimuth 155°) at 45° from horizontal, true width is not known as the orientation of the orebody is not fully understood.
