As governments around the world commit to investments in clean energy, the need for precious and base metals has resulted in unprecedented growth worldwide. Precious and base metals, such as copper, are needed now more than ever before for EV batteries, power grids, wind and solar technologies and EV charging.

Copper is an essential component for the transition towards clean energy and is an innovative solution fusing together energy efficiency, renewables, transportation and smart grids.

The clean energy movement also goes beyond the resource –– it extends to every aspect of a company’s operations. Naturally, companies that supply these metals should be sustainable in the long term, support local communities, care for the environment, build the global economy and accelerate the transition to a low-carbon world in order to productively support the green economy. Not only is investing into ESG-focused companies socially-responsible but it has been shown to reduce portfolio risks and increase returns with greater long-term success. As a result, mineral companies with ESG models will likely attract investors seeking these benefits.

Lion Copper and Gold (TSXV:LEO,OTCQB:LCGMF) is a mineral exploration company focused on the MacArthur Project in Mason Valley, Nevada. The company holds the largest land position in the Mason Valley district, which is home to a large metal endowment with numerous other known copper deposits. Nevada was the top mining jurisdiction in the world in 2020 based on investment attractiveness, according to the Fraser Institute.

As of March 2022, Lion Copper and Gold announced its entering into an option to earn-in agreement with Rio Tinto America (NYSE:RIO) to advance studies and exploration at Lion CG’s copper assets in Mason Valley, Nevada.

The MacArthur project is located 50 miles southeast of Reno, and hosts sulfide resources that are open in most directions with upside potential and high-grade mineralization. The project has a measured and indicated resource of 676 million pounds of contained copper at average grades of 0.21 percent and an inferred resource of 980 million pounds of contained copper at average grades of 0.20 percent. The resource is estimated at cut-off grades of 0.12 TCu percent. MacArthur is a large-scale, low-cost heap leach project with the potential for near term production of pure copper cathode.

Lion Copper and Gold has committed to an ESG model. The company’s “Conservation by Design” approach focuses on environmental sustainability through best practices, sound science and state-of-the-art technology. This approach progresses the company’s mission of water conservation and minimal emissions in the renewable economy. Specifically, Lion Copper and Gold plans to electrify its equipment, generate on-site solar power, recycle water in its processing facilities and invest in other eco-friendly technologies.

The company is currently focused on continuing to advance its MacArthur project through ongoing study and permitting efforts on its copper deposit and exploration of the sulfide resource. Lion Copper and Gold updated its resource estimate in the first quarter of 2022, intends to enhance metallurgical approaches, optimize the production schedule and begin a permitting and execution plan. and complete a pre-feasibility study on the MacArthur project by the third quarter of 2022.

Lion Copper and Gold is led by a highly experienced management team with a track record of success in the mineral exploration industry. Lion Copper and Gold's management team has local mining experience in Nevada as well as the ability to build and finance its flagship asset. The company’s MacArthur project also has support from the local, tribal, state and federal governments.

The company’s flagship MacArthur project is located in Mason Valley, Nevada. The property has access to extensive infrastructure and is situated in the center of the district which is ideal for mine development and district consolidation.

The project features a sulfide resource with upside potential and a large oxide copper deposit with the potential for near-term production of pure cathode copper. The deposit has a measured and indicated resource of 676 million pounds of contained copper at average grades of 0.21 percent, and an inferred resource of 980 million pounds of contained copper at average grades of 0.20 percent. The resource is estimated at cut-off grades of 0.12 TCu percent.

The project contains open-pittable resources that may result in large-scale, low-cost heap leach operations. Lion Copper and Gold has community support for the MacArthur project from local, tribal, state and federal governments as well as local mining experience. The company updated its resource estimate in the first quarter of 2022 plans to enhance metallurgical approaches, optimize the production schedule and begin a permitting and execution plan. Lion Copper and Gold entered into an agreement with Rio Tinto America, under which Rio Tinto fully funds the feasibility study on the MacArthur project, setting forth specific timelines for execution.

Positioned directly east of the Golden Triangle in British Columbia. The property has many comparable features to the Eskay Creek gold deposit, held by Eskay Mining (TSXV:ESK,OTCQX:ESKYF). Positioned just north of Stewart, BC, the resource holds reserves in excess of 4.36 million tonnes.The Chaco Bear project, positioned southeast of this noteworthy deposit, aims to identify the full potential of this gold project by actively engaging in testing.

The Ashton property is positioned near Lytton, BC and represents one of the earliest-staked properties in the Spences Bridge Gold Belt. This area is long-known, though is currently experiencing a surge of popularity due to modern interpretation of historical data. Companies like Westhaven Gold (TSXV:WHN) are actively pursuing interests in the area. With Ashton’s early stake in the area, it has potential to become a prime exploration opportunity. Lion Copper & Gold has already identified multiple drilling targets in the area.

In early 2022, Lion Copper and Gold announced the acquisition of the Montana Blue Copper-Gold Prospect. Located approximately 25 miles west-northwest of Helena, Montana, it’s centered on the Late Cretaceous Blackfoot City Stock (BCS). The BCS was intruded into the Black Mountain syncline, composed primarily of a Paleozoic sequence of limestone, dolomite, shale, and sandstone.

This area crystallized at the same time as the nearby Boulder batholith, which is host to the world-famous Butte copper mines. The deal involved the 7,400 acres staked, encompassing over 14 historic small mines that historically produced high-grade gold, copper, and tungsten.

Lion Copper and Gold Corp. (TSXV: LEO) (OTCQB: LCGMF) ("Lion CG", or the "Company") is pleased to announce that further to its March 21, 2022 news release, the TSX Venture Exchange has approved the Company's Option to Earn-in Agreement (the "Agreement") with Rio Tinto America Inc. ("Rio Tinto") dated March 18, 2022.

Under the Agreement, Rio Tinto has the option to earn up to a 75% interest in the Company's Mason Valley, NV assets, including the historic Yerington mine, greenfield MacArthur Project, Wassuk property, the Bear deposit, and associated water rights (the "Mining Assets"). In addition, Rio Tinto will evaluate the potential commercial deployment of its NutonTM technologies at the site. NutonTM offers copper heap leaching technologies developed by Rio Tinto to deliver greater copper recovery from mined ore and access new sources of copper such as low-grade sulphide resources and reprocessing of stockpiles and mineralised waste. The technologies have the potential to deliver leading environmental performance through more efficient water usage, lower carbon emissions, and the ability to reclaim mine sites by reprocessing waste.

Upon completion of a feasibility study, Rio Tinto and Lion CG will decide whether to create an investment vehicle into which the Mining Assets will be transferred, with Rio Tinto holding not less than a 65% interest in the investment vehicle. If Rio Tinto elects not to create the investment vehicle, then Lion CG shall grant to Rio Tinto a 1.5% net smelter return royalty ("NSR") on the Mining Assets. Rio Tinto may elect to fund up to sixty million U.S. dollars ($60,000,000) of Lion CG's project financing costs in exchange for a 10% increase in Rio Tinto's ownership percentage. In addition, upon mutual agreement of Rio Tinto and Lion CG, Rio Tinto may fund an additional forty million U.S. dollars ($40,000,000) of Lion CG's project financing costs in exchange for an additional 5% increase in Rio Tinto's ownership percentage. Rio Tinto may also acquire 1.0% or a pro rata portion thereof for (a) each US$4,500,000 paid for any additional infrastructure that Lion CG and Rio Tinto mutually agree to pursue; and (b) each US$4,500,000 which Rio Tinto funds for the feasibility study in excess of the US$50,000,000. If Lion CG's ownership percentage in the investment vehicle is diluted to 10% or less, then Lion CG's ownership interest will be converted into a 1% uncapped NSR. Please see the Company's March 21, 2022 news release for additional information on the Agreement with Rio Tinto.

Ero Copper Corp. (TSX: ERO, NYSE: ERO) ("Ero" or the "Company") is pleased to announce the discovery of a regional nickel sulphide system within the Curaçá Valley over an initial strike length of five kilometers. The system remains open in all directions and is highlighted by multiple surface expressions of nickel mineralization. Results from first-pass drilling conducted on two of the identified zones along the currently interpreted northeast and southwest boundaries of the system are highlighted by:

The newly discovered nickel system, known as the "Umburana System", is located approximately 20 kilometers from the Company's existing Caraíba processing facilities. The system was discovered using new detailed field mapping and soil geochemistry collected during the Company's 2021 and 2022 exploration programs in conjunction with the Company's airborne electromagnetic ("AEM") survey. First-pass drilling comprised of 48 drill holes initially testing where ultramafic rocks have been mapped at surface. The ongoing program has identified large intervals of disseminated and interstitial nickel sulphides as well as zones of high-grade semi-massive (containing approximately 30% to 60% sulphides) and massive sulphides (containing approximately 60% to 80% sulphides), with massive sulphide intercepts up to 1.5 meters in thickness grading up to 6.59% nickel (7.11% NiEq). Nickel mineralization outcrops at surface, is evident in trenches and remains open down-plunge. Maximum depth of drilling to date is approximately 300 meters below surface. There are four exploration drill rigs currently operating on the system.

Commenting on the discovery, David Strang, Chief Executive Officer, said "This is a significant and pivotal moment for the Company and, more broadly, for the region. To think that copper in the Curaçá Valley was first documented in the late 1700s and we are just now discovering nickel sulphide mineralization not far from where copper has been mined for over 40 years is truly remarkable. As a Company, we have been working to better understand the potential for nickel occurrences since first observed within the Vermelhos Mine in 2018. With newly compiled datasets, dedicated resources focused exclusively on understanding and finding nickel and a complete re-look of several historic datasets this past year, our efforts and persistence have paid off. We believe today's results confirm the Curaçá Valley's potential to be a globally significant magmatic sulphide district for both copper and nickel."

Mike Richard, the Company's Chief Geological Officer, added "From my perspective, this is the most significant development in the Curaçá Valley's regional exploration program to date. I am incredibly proud of our exploration team for their contributions to making our first nickel discovery and believe we are at the early stages of unlocking significant value for the Company. These zones are the first targets we have drill tested in what is an emerging new exploration frontier, and based upon results to date, we have good geological evidence to support the "key" signatures for nickel potential that we expect will vastly enhance our nickel exploration program in the months and years ahead."

The first significant documented occurrence of nickel sulphides in the Curaçá Valley was made by the Company during the Vermelhos Mine development, and later in discrete zones of copper-nickel massive sulphides within the Siriema Deposit in late 2018 and 2019, respectively. Detailed geologic mapping, comprehensive multi-element soil geochemistry and re-interpretation of the Company's available geophysical datasets throughout 2021 and the first-half of 2022 has resulted in the discovery of a new nickel system featuring favourable geology with coincident geochemical and geophysical anomalies. To date, detailed exploration has focused on two target areas located at the interpreted northeast and southwest boundary of a five-kilometer system each characterized by multiple expressions of outcropping nickel mineralization in the form of gossans, geochemical and geophysical anomalies - all associated with mafic-ultramafic intrusions. Please refer to Figure 3 for a plan view map of the Umburana System.

Initial drill-testing at the northeast and southwest boundaries of the currently known system has identified nickel sulphide mineralization ranging from disseminated and interstitial nickel sulphides (containing less than 10% sulphides) extending over 50 meters in thickness to patchy net-textured sulphides (containing approximately 10% to 30% sulphides) with localized centimeter up to 1.5 meter thick massive-sulphide lenses (containing approximately 60% to 80% sulphides) grading up to 6.59% nickel (7.11% NiEq). Mineralization within these zones is hosted by pyroxenite and peridotite ultramafic rocks. Sulphide minerals are mainly pyrrhotite, pentlandite (loop-textured where massive sulphide, see Figure 1) with lesser pyrite and chalcopyrite. Loop-textured pentlandite is an important geologic indicator commonly observed in magmatic nickel sulphide deposits. The full extent of the system is unknown at this time. Mineralization remains open down-dip and along strike. Exploration work remains ongoing.

No metallurgical testwork has been completed to date. Metallurgical samples from select drillhole composites within the Umburana System are currently being collected for preliminary testwork including detailed mineralogy as well as laboratory flotation tests. Where applicable, nickel equivalent ("NiEq") in this press release has been calculated using the following formula: NiEq = Ni + (Cu x $3.50/$9.80) + (Co x $25.50/$9.80). No adjustment for metallurgical recoveries has been made when calculating NiEq.

At the northeast extent of the Umburana System nickel-bearing ultramafic rocks have been identified over 1.4 kilometers north-south and up to 200 meters east-west using surface mapping supported by soil geochemistry and 20 trenches. To date, 24 holes with assay results have been received. Mineralization within the VB Zone is primarily comprised of disseminated, and patchy net-textured nickel sulphide mineralization with zones of high- grade massive sulphide mineralization featuring localized thickening of up to 1.5 meters grading up to 6.59% nickel (7.11% NiEq). Within the VB Zone, higher-grade mineralization appears to be focused at the base of a pyroxenite intrusion. Mineralization occurs predominantly within orthopyroxenites ranging from isotropic to locally banded.

Within the central high-grade portion of the VB Zone, results are highlighted by two holes, VB-05 and VB-17, both located on the same section, which intercepted high-grade massive sulphides of up to 1.5 meters grading up to 7.11% NiEq within broader mineralized intervals ranging between approximately 17 and 20 meters grading between 0.75% NiEq to 1.37% NiEq. Please see "VB Zone Intercepts" table below for complete results.

The deepest drilling to date within the VB Zone is highlighted by hole VB-25 that intercepted high-grade massive sulphide of up to 1.4 meters grading up to 5.30% NiEq, approximately 290 meters below surface. When combined with surface trenching and previously highlighted intercepts in hole VB-05 and hole VB-17, high-grade nickel sulphide mineralization can be traced from surface to over 300 meters down-dip. Additional exploration work to understand the relationship between these high-grade massive sulphide intercepts and other intercepts of high-grade nickel mineralization identified throughout the VB Zone remains ongoing.

There are currently three drill rigs active within the VB Zone. Please see Figures 4 and 5 for additional details on drill hole locations and intercepts.

NSI denotes no significant intercept grading above 0.10% Ni. Drill holes were drilled from surface. Holes not included are either pending assay results or have been included in a different section of this press release. The length of intercept may not represent the true width of mineralization. Values may not add up due to rounding. From, To and Length are rounded to the nearest tenth of a meter.

(*) denotes interval of massive sulphide within larger reported intercept.

Figure 1: Drill core from the deepest intercept to date in the VB Zone (hole VB-25 at ~319 meters) highlighting loop textured pentlandite in ( a ) and high-grade massive sulphide intervals within the zone ( b ).

At the southwest extent of the Umburana System, located approximately 20 kilometers from the Company's Caraíba milling operations and approximately 3.2 kilometers southwest of the VB Zone, nickel-bearing ultramafic rocks have been identified over 500 meters in strike- length and approximately 50 meters in apparent thickness using surface mapping supported by geochemistry, AEM response and eight trenches. To date, 24 holes with assay results have been received. Mineralization within the LZ Zone is primarily comprised of disseminated nickel sulphide mineralization with intercalated intervals of interstitial and net-textured sulphides (see Figure 2). Within the 500-meter identified strike length of the LZ Zone, a zone of higher- grade mineralization has been identified within the footwall of the mafic-ultramafic intrusion associated with a peridotite layer.

Results within the footwall of the LZ Zone are highlighted by two holes, LZ-03 and LZ-07, both located on the same section, which intercepted broad mineralized intervals between 18 and 24 meters grading between 0.97% NiEq to 1.14% NiEq. South along strike, hole LZ-06, drilled approximately 50 meters from holes LZ-03 and LZ-07, intercepted 22.5 meters grading 1.02% NiEq. When combined with surface trenching, higher-grade mineralization within the footwall of the LZ Zone can be traced from surface approximately 190 meters down-dip. Please see "LZ Zone Intercepts" table below for complete results.

The deepest drilling to date within the LZ Zone is highlighted by hole LZ-24 that intercepted broad mineralization over approximately 46 meters grading 0.27% NiEq from approximately 185 meters downhole. At the bottom of this broader mineralized intercept, an extension of the high-grade peridotite layer of the footwall zone, approximately 200 meters below surface, was intercepted over 5.7 meters grading 1.08% NiEq indicating the footwall zone remains open along strike to the north and to depth. Hole LZ-24 is located approximately 50 meters north of the higher-grade mineralization identified in the footwall highlighted by holes LZ-03 and LZ-07, and approximately 100 meters north of the footwall intercept in hole LZ-06. Exploration drilling to understand the relationship between these higher-grade intercepts remains ongoing, and there is currently 1 drill rig working within the LZ Zone. In parallel, exploration efforts at the LZ Zone continue to use systematic geological mapping, trenching, ground electromagnetic ("EM") surveys and borehole EM surveys.

Please see Figure 6 and 7 for additional details on drill hole locations and intercepts.

NOTE ON NI 43-101 COMPLIANT TECHNICAL REPORT(S)

The conversion of drill results presented in this press release into NI 43-101 compliant mineral resources and mineral reserves all require additional work and analysis that remains ongoing. To date, there has been insufficient exploration and accompanying analysis to define a mineral resource and it is uncertain if further exploration will result in this nickel system being delineated as a mineral resource. Accordingly, the results herein may not be included in future NI 43-101 compliant mineral resources or mineral reserves depending on the results of this additional work and analysis, and other technical and/or economic reasons.

QUALITY ASSURANCE & QUALITY CONTROL

In support of its ongoing Umburana System exploration program, the Company is currently drilling on surface using third-party contracted core drill rigs. During the period from January 2022 through September 2022, third-party drill rigs were operated by Major Drilling do Brasil Ltda., and Layne Christensen Co. both of whom are independent of the Company. Drill core is logged, photographed and split in half using a diamond core saw at the secure core logging and storage facilities of Mineração Caraíba S.A. ("MCSA"). Half of the drill core is retained on site and the other half core is used for analysis, with samples collected on one- meter sample intervals unless an interval crosses a geological contact. All sample preparation is performed in MCSA's secure on-site laboratory. Total nickel and copper is determined using a nitric-hydrochloric acid digestion and Atomic Absorption Spectrometry and/or Titration at the on-site laboratory. All sample results during the period have been monitored through a QA/QC program that includes the insertion of certified standards, blanks, and pulp and reject duplicate samples. Check-assays for nickel and copper were submitted to ALS Brasil Ltda's facility located in Vespasiano, Minas Gerais, Brazil, at a rate of approximately 5%. ALS Brasil Ltda is a subsidiary of ALS Limited and is independent of the Company.

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed or incorporated by reference in this press release have been prepared in accordance with NI 43-101 and are classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. NI 43-101 differs significantly from the disclosure requirements of the Securities and Exchange Commission (the "SEC") generally applicable to U.S. companies. For example, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in NI 43-101. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this press release may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the CIM Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.

American West Metals Limited (American West Metals or the Company) (ASX: AW1) is pleased to report that initial assay results from drill hole ST22-10 have confirmed a significant discovery at the Storm Copper Project (Storm or the Project) on Somerset Island, Nunavut, Canada.

“Iamverypleasedtobeabletoreportthatinitial assays from drill hole ST22-10 confirm the presence of sediment hosted type copper and zinc sulphide mineralisation, with huge implications for the potential metal endowment of the project.

“These results demonstrate that – in addition to the near-surface high-grade copper deposits – we have a second type of copper deposit at Storm. This sedimentary copper mineralisation style is typically associated with very large deposits, such as the large-scale copper deposits in the Congo and the Kupferschiefer deposits in Central Europe.

“The discovery drill hole at Storm is associated with a series of large IP, EM and gravity anomalies that sit below or adjacent to the known high-grade copper prospects and major faults. These features occur across a zone more than 5,000m long, supporting the potential for a very large sedimentary copper system.

“This is a tremendous exploration opportunity and we are already planning follow-up exploration and drilling.

“Further assays from the Storm drill program are due soon and we look forward to reporting on these as they come in.”

NEW STYLE OF COPPER AND ZINC SULPHIDES CONFIRMED

Drill hole ST22-10 intersected a thick sequence of sulphide mineralisation hosted within carbonate sediments. The drill hole was targeting a large EM anomaly to the west, and deeper than the near surface high-grade 4100N Zone.

Approximately 68.8m of chalcopyrite, pyrite and sphalerite mineralisation was intersected from 277m downhole in drill hole ST22-10 (approx. 230m vertical depth). The mineralisation is interpreted to be stratabound and is hosted within a vuggy, bituminous and fossiliferous carbonate unit.

Visual observations of chalcopyrite and sphalerite in the drill core have now been confirmed by assays within the sampled intervals from ST22-10.

Of the sulphide mineralised zones, only portions containing clear and abundant chalcopyrite and sphalerite were sampled with the aim of confirming sediment hosted copper and zinc. Most of the pyrite-dominant zones were excluded from samples submitted for assay - see Table 1 for assay results and Figure 3 for a geological cross section of the drill hole. The results received confirm the presence of sediment hosted copper and zinc sulphide mineralisation, and have verified the discovery of this new style of mineralisation at Storm.

Geophysical properties logging of sections of the core as well as further sampling will be conducted on ST22-10 to refine the targeting model for follow-up drilling.

ST22-10 is the deepest drill hole completed at the Storm Project this season and highlights the outstanding exploration potential of the project area. Compilation of historical induced polarization (IP), gravity and electromagnetic (EM) data reveals a series of large anomalies that sit under, and adjacent to the known high- grade copper mineralisation and graben fault system.

The metal associations, zonation and geophysics suggest that the drill hole is potentially on the edge of a stronger mineral system.
