We will first get a presentation about the company’s occupations and afterwards a visit to a site. 5 | P a g e A short introduction to LKAB ‘Our commitment extends far beyond the mines’ Quick Facts Ownership: LKAB Product: Iron Ore Location: Kiruna, Northern Sweden Current production rate: 15Mt/year (2006) Start of production: 1890 (open pit), 1960s (underground) Mining method: Automated sub-level Caving Luossavaara-Kiirunavaara Aktiebolag (LKAB) is a Swedish mining company which mines iron ores at Kiruna and at Malmberget. Their production is sold throughout much of the world. LKAB has mines, processing plants and ore harbors. They produced 27.2 Mt of iron ore during 2017, how did they get there? History If the legend is to be believed it all started with a squirrel hunt outside the village Masugnsbyn, near Junosuando in Torne Valley. A farmer found a peculiar black piece of stone and brought the stone to the merchants in Tornea and it was classified as iron ore. This discovery was in 1642 and started the mining and industry history in Malmfälten, which eventually lead to the mining company LKAB. The company was established in 1890 and has been an important cog in Sweden’s export industry and industrial development for more than a century. They have also been a reliable supplier and business partner to the European steel industry for the same length of time. (LKAB official website) A few highlights of LKAB: (LKAB official website) 1890 – establishment of LKAB with Carl Johan Ljunggren as first managing director. 1898 – The Swedish and Norwegian parliaments decide that the Ore Railway should be extended. Also, Kiruna is being developed by Hjalmar Lundbohm. 1907 – The Swedish State becomes a part-owner of LKAB and the trams begin to roll in Kiruna 1910 – The first processing plant is commissioned in Malmberget 1933 – After WW1 the ore production dropped to its lowest levels because of global economic recession. 1936 – After the recession the production rises to higher than before. 1955 – The first pelletising plant is inaugurated in Malmberget. 1965 – A new harbor in Lulea is inaugurated together with a new mine in Svappavaara and the first pelletising plant in Kiruna. 1969 – Miners’ strike begins, they strike for 57 days with a result in a switch to monthly salaries. 1974 – The record year for LKAB, in which 30 million tons of ore were produced. 1976 – LKAB becomes fully nationalized, with AB Statsföretag as the owner. 1981 – Olivine pellets become a great sales success. 1985 – Record profit of more than 1 billion SEK. 1997 – An experimental blast furnace for product development is built in Lulea. 6 | P a g e Kiruna The LKAB Kiruna operation is located in Kiruna in the north of Sweden (145 km north of the Arctic Circle). The city situated at an altitude of about 530m. The city of Kiruna/mine is connected to a railway system between Lulea and the ice-free harbor of Narvik (Norway). The Kirunavaara mine started production in the beginning of the 20th century. They started with open pit which was followed by underground mining. The Kiruna iron ore mine is famous for its high level of automation. Geology LKAB’s exploration takes place both in association with existing mines and in new areas. The mining areas of LKAB are Kiruna, Marlmberget, Gruvberget, Leveäniemi and Mertainen. In this report Kiruna will be discussed as that is the site we will visit. The original reserve at Kiruna was some 1,800Mt. As of the end of 2008, LKAB estimated that the current proven reserve at the mine is 602Mt grading 48.5% iron. In this Kiruna mine site, the reserves and resources are as follows from table 1 nowadays. KIRUNA QUANTITY MT PERCENT FE 2016 2015 2016 2015 KNOWN 2 12 41.4 48.3 INDICATED 159 217 45.4 45.8 INFERRED 37 83 40.3 44.2 Table 1, Kiruna mine quantity and percentage of Fe. These ores are situated of the Fennoscandian shield and occur in a mid-Proterozoic continental setting. The formation is underlined by Archaen granitic gneiss and Lower Proterozoic greenstone basement. The host rocks consist of alkalic rhyolite, tachyte and tachyandesite ash flows and lava flows, shown in figure 1. Figure 1, Geological map of the Kiruna district showing the setting of the iron ores. Kiruna (1), Luossavaara (2), Rektorn (3), Henry (4), Haukivaara (5), Nukutusvaara (6) and Tuollovaara (7). (Evans 2000) The Kiruna orebody is 4000m long, 80-120m thick and reaches a depth of about 2000m. It was formed approximately 1.600Ma ago as a result of intense volcanic activity. Iron-rich solutions precipitated on to a syenite porphyry footwall. The ore layer was then covered by other volcanic deposits and sedimentary rocks. Later the whole orebody was tilted to its current dip of 5 -6 (Hitzman et al, 1992). 7 | P a g e Mining and Processing As already mentioned earlier the Kiruna iron ore mine started with open pit mining and after that they started sublevel caving, with sublevels spaced at 28.5m vertically. With a burden of 3.0-3.5m per ring, this yields around 8,500t for each blast. LKAB subsidiary Kimit AB supplies the explosives and prepares the holes for blasting. The main haulage level at Kiruna lies at a depth of 1,045m, with the mine’s ore-handling systems capable of handling 26Mt/y of run-of-mine rock. The transportation of the ore is done using the extensive railway system which brings the ore to the harbor. This is shipped to Europe and all around the world because of high quality. Growth prospects Although the 1,045m haulage level was originally expected to serve the mine until at least 2015, higher production rates meant that a new level and shaft-hoisting system would be needed in future. LKAB studied the options for this, with a main haulage system to be located at a depth of 1,365m. The new main level will deepen the mine by 320m. A new haulage level will be constructed at 1,365m depth for shuttle-train traffic. New mine locomotives and cars will be bought for a 1,435mm-wide track that will be wider than the previous mine levels. Ore will be transported via remote controlled shuttle trains to the crushing plant. The ore will then be skip-hoisted approximately 1.4km vertically in two stages to the processing plant. Mining will be carried out in ten production areas. Each area will be equipped with an access road, ventilation and media systems, and multiple ore passes and rock chutes.

  • Exploration Drilling Update at the Historic High Grade Sala Silver Mine
    ASX ANNOUNCEMENT 7th July 2021 Sala Silver-Lead-Zinc Project, Sweden Exploration Drilling Update at the Historic High Grade Sala Silver Mine Maiden Alicanto exploration drilling underway with first two diamond core drill holes completed targeting the Prince Lode - Broad Sala Style sulphide mineralisation intercepted in both holes including a step out 140m down dip of historic intersections of 37.2m @ 50g/t Ag & 6.1% Zn and 15.9m @ 157 g/t Ag & 4.2% Zn7. Assays are Pending. Key Points • Maiden Alicanto exploration drilling at Sala Silver Project progressing well with the first two holes completed of a focussed and fully funded 3,000 metre initial drill program. • Visible Silver, Lead and Zinc mineralisation intercepted over broad intervals in both drill holes with the zones having similar mineralisation characteristics to those seen within the historic Sala mine. Refer photos. • Drill holes (SAL2101 and SAL2102) intersected multiple zones (33.8m and 32.02m respectively) of galena-sphalerite as both massive sulphide veins and semi massive sulphide mineralisation. • Drill core is currently being processed at the laboratory with assays expected in coming weeks. • Drilling is ongoing with a second diamond core rig mobilising to site in the coming weeks. • The Sala Project is a significant historical producer of Silver-Lead-Zinc with over 200 Moz of silver (at an average grade of 1,244 g/t) and lead (at between 1% and 2%) and 12% zinc mined up until the early 1900’s2. The Alicanto drilling is some of the first modern drilling to be completed at the deposit. • Trial of down hole electromagnetic (DHEM) surveys indicates a modellable response from mineralisation, with further drill hole targets defined from the completed survey.

  • Mercury (Hg) Mineral Evolution: a Mineralogical Record of Supercontinent Assembly, Changing Ocean Geochemistry, and the Emerging Terrestrial Biosphere

ABSTRACT Analyses of the temporal and geographic distribution of earliest recorded appearances of the 88 IMA-approved mercury minerals plus two potentially valid species exemplify principles of mineral evolution. Metacinnabar (HgS) and native Hg are the only two species reported from meteorites, specifically, the primitive H3 Tieschitz chondrite with an age of 4550 Ma. Since the first terrestrial appearance of cinnabar more than 3 billion years ago, mercury minerals have been present continu- ously at or near Earth’s surface. Mercury mineral evolution is characterized by episodic deposition and diversification, perhaps associated with the supercontinent cycle. We observe statistically significant increases in the number of reported Hg mineral localities and new Hg species at ~2.8–2.6, ~1.9–1.8, and ~0.43–0.25 Ga— intervals that correlate with episodes of presumed supercontinent assembly and associated orogenies of Kenorland (Superia), Columbia (Nuna), and Pangea, respectively.

  • Solo Silvergruva Under Gångno Sekler
    Solo silvergruva under gångno sekler Av Bob Engelbertsson Sala silvergruva är ett intressant kapitel i Sveriges industriella historia på flera sätt. Genom mer än 400 år kan man följa hur gammal och ny teknik möttes, både vid malmbrytningen och vid silverframställningen. Silvermalmen, bestående av framför allt silverhaltig blyglans, låg som oregelbundna malmkroppar, vilket gjorde sökandet stundtals kompli­ cerat och riskfyllt.1 Vägen från malm till silvertacka var omständlig och föranledde en rad tekniska problem. I denna uppsats ges först en översikt av gruvans historia och betydelse i olika avseenden. Därefter följer ett antal exempel på hur gammal och ny teknik möttes. Några drog ur Silverfyndigheterna i Sala upptäcktes troligen någon gång i slutet av gruvons historia 1400-talet. Gruvan finns omnämnd i ett biskopsbrev från 1511. År 1512 utfärdades det första privilegiebrevet. Gruvdriften bör då ha pågått under några decennier. 2 På 1500-talet exploaterades de södra delarna av det drygt 700 meter långa och 200 meter breda gruvområdet. 1. Sala silvergruva 1724.

  • Alicanto Minerals Secured Tenure of the High-Grade Sala Silver Project in Sweden
    ASX ANNOUNCEMENT 30 April 2021 March 2021 QUARTERLY ACTIVITIES REPORT Exploration results support exploration strategy at Greater Falun Copper-Gold Project, Sweden Drilling reveals high grade copper, gold and silver from never before drilled targets HIGHLIGHTS Exploration - Greater Falun Project • First holes at Greater Falun copper-gold-silver project in Sweden return shallow, high-grade assays • The holes were drilled at the Swamp Thing and Heden prospects, which sit within 15km of the world- class Falun copper-gold mine (closed in 1992) • The results are particularly important because they also support Alicanto’s belief that Greater Falun is a Skarn system, not Volcanogenic Massive Sulphides (VMS) • Multiple outcropping granitic intrusions or “heat engines” delineated in drilling believed to be the drivers of the proximal skarn mineralisation • Structural folding of the newly defined stratigraphic sequence creating “bonanza” style widths at Falun, with the potential also seen in most recent drilling and field mapping within the Greater Falun project • Further assays pending from the now-completed 4,000m drilling campaign • New, 20,000m drilling campaign now underway with two diamond drill rigs in action and a third being mobilised to Sala • The Greater Falun Project is located in the Bergslagen region, which hosts world-class base and precious metals projects • Bergslagen is a tier-one location with a mining history of 1,000 years, producing over 100Mt of high- grade base and precious metals ore in modern times The Swamp Thing, Sweden1 • Four drill holes were completed at The Swamp Thing (Enmyregruvan), ST20-01 to ST21-04. ST20-01 intersected a mineralised zone with copper-gold skarn in the contact between limestone and an intruding apophyse of a feldspar porphyry, showing what the potential target mineralisation could look like within this environment.

  • Bonanza Silver and Zinc Grades in Alicanto's First Hole at Sala Project
    ASX ANNOUNCEMENT 3rd August 2021 Bonanza silver and zinc grades in Alicanto’s first hole at Sala project, Sweden Assays up to 348g/t silver, 12.2% zinc, 5.9% lead 140m down-dip from historical intersection; Assays pending from second and third holes, which both contain visual mineralisation Key Points • First assays from Alicanto’s maiden drill hole (SAL21-01) confirm high-grade silver, lead and zinc from the Prince Lode at Sala. Intersections include: • 3.8m @ 7.7% Zn and 9g/t Ag from 572.75m • 6.8m @ 123 g/t Ag, 2.3% Pb and 1.4% Zn from 589.75m (Including 0.95m @ 348 g/t Ag, 5.9% Pb & 4.06% Zn) from 592.58m • Mineralisation is adjacent to the historic Sala Mine which produced over 200Moz of silver at an average grade of 1,244 g/t Ag. This system is interpreted to be a polymetallic skarn with geological similarities with major producing underground mines in the areas such as Garpenberg operated by Boliden and Zinkgruvan operated by Lundin • Alicanto intersections represent a 140m step out down-dip from historical drill intersection of 37.2m @ 50g/t Ag & 6.1% Zn and 15.9m @ 157 g/t Ag, & 4.2% Zn2,7. This includes high grade intervals of: • 7.1m @ 81 g/t Ag, 10.4% Zn & 0.6% Pb2 • 5.5m @69 g/t Ag, 7.4% Zn & 0.8% Pb2 • 11.9m @ 15 g/t Ag, 8.1% Zn & 0.1% Pb2 • 9.85m @203 g/t Ag, 6.4% Zn 0.8% Pb2 • 0.8m @ 1,034 g/t Ag, 1.5% Zn, 2.4% Pb2 • Visuals from Alicanto’s second and third holes (SAL21-02, SAL21-03) indicate similar style and tenor of mineralisation as SAL21-01 with multiple lenses of sulphide mineralisation.
