Investor Insight

With strategic, US-based assets, Trigg Minerals is well-positioned to become a cornerstone supplier of antimony and tungsten into the United States and allied markets. With a sharpened focus on critical minerals in Tier-1 jurisdictions, Trigg is executing a strategy that aligns with urgent national security and energy transition needs.

Overview

Trigg Minerals (ASX:TMG,OTCQB:TMGLF) is an emerging leader in the global critical minerals space, focused exclusively on the development of antimony and tungsten assets in the US – both metals designated as critical minerals by the United States, Canada, Australia and the European Union for its role in national defense, energy transition technologies, and advanced industrial applications.

Global supply of both antimony and tungsten is highly concentrated, with more than 80 percent controlled by China and Russia. Export restrictions, sanctions and the depletion of strategic stockpiles have created acute shortages, driving demand for alternative, conflict-free sources. This geopolitical backdrop creates a once-in-a-generation opportunity for new suppliers to anchor Western supply chains.

Trigg’s strategy is firmly focused on developing critical minerals projects in Tier-1 US jurisdictions, where stable regulatory frameworks, established infrastructure and strong government support provide a competitive advantage.

The company’s flagship Antimony Canyon project in Utah is one of the largest undeveloped antimony systems in the country, now secured through patented mining claims that streamline the pathway to production. Complementing this is the Tennessee Mountain tungsten project in Nevada, a historic tungsten district with confirmed high-grade mineralisation, and the newly acquired Central Idaho antimony project, which offers district-scale potential in a historically productive region.

By advancing this portfolio, Trigg aims to establish itself as a vertically integrated supplier, from mine development through to downstream smelting and refined metal production. With strong shareholder support, active engagement with US government and defence stakeholders, and membership in international industry associations, Trigg Minerals is positioned to play a leading role in rebuilding secure Western supply of antimony and tungsten.

• Strong financial position and strategic investment support, including backing from Tribeca Investment Partners.
• Proposal to rebrand as American Antimony and Tungsten at the November 2025 AGM to reflect US focus.

Key Project

Antimony Canyon Project

Antimony Canyon, located in Utah, is Trigg’s flagship project and one of the largest undeveloped antimony systems in the United States. Historically mined during the 20th century but never subject to modern exploration, the district hosts multiple high-grade stibnite deposits. In 2025, Trigg consolidated control through the acquisition of 20 patented claims, giving the company full ownership of both surface and mineral rights. This control materially de-risks permitting by allowing the project to proceed under Utah’s streamlined Mined Land Reclamation Act, avoiding lengthy federal processes.

An exploration target of 6.1 to 6.9 million tonnes (Mt) at 1.4 to 2.3 per cent antimony, containing between 86,000 and 158,000 tonnes of antimony metal, has been established on these claims. Sampling programs have confirmed exceptional grades, including channel results up to 33.2 percent antimony. With no active US antimony production, Antimony Canyon offers a unique opportunity to establish domestic supply, with Trigg advancing studies for a pilot-scale mining operation and downstream smelting in partnership with Metso, leveraging Ausmelt technology for the production of refined antimony metal.

Tennessee Mountain Tungsten Project

In August 2025, Trigg expanded into tungsten through the acquisition of the Tennessee Mountain project in Nevada, another Tier-1 US jurisdiction. This historic mining district hosts the Garnet Mine and widespread skarn-hosted tungsten mineralisation. Historical trenching and drilling reported thick intersections of mineralised zones, including 24.9 metres at 0.65 percent tungsten trioxide and 10.67 metres at 0.98 percent tungsten trioxide. A non-JORC historical estimate of 0.71 Mt, grading 0.3 to 0.5 percent tungsten trioxide, underscores the scale and potential of the system. With tungsten also recognised as a critical mineral for defence and clean energy technologies, Tennessee Mountain provides diversification and growth within Trigg’s US portfolio.

Central Idaho Antimony Project

In September 2025, Trigg acquired the Central Idaho antimony project, located within the historically productive Swanholm Mining District. Early fieldwork has already confirmed very high-grade mineralisation, including assays up to 17.6 percent antimony from surface samples, with associated gold values. The project covers a district-scale landholding in an area geologically analogous to Perpetua Resources’ Stibnite gold project, which has received substantial US federal support. With minimal historic disturbance and no legacy tailings, the project offers a clean environmental baseline and a potentially straightforward permitting pathway.

Australian Projects

While Trigg’s near-term focus is firmly in the US, the company maintains optionality through its Australian portfolio. The Wild Cattle Creek deposit in New South Wales contains a JORC 2012 resource of 1.52 Mt at 1.97 percent antimony, representing ~30,000 tonnes of contained metal and ranking as one of the world’s highest-grade undeveloped antimony deposits. Additional Australian projects, including Taylors Arm, Spartan and Nundle, as well as the Drummond gold project in Queensland, provide longer-term exploration upside.

Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) (‘Sitka’ or the ‘Company’) is pleased to announce analytical results for three diamond drill holes completed at the Contact Zone target located at its 100% owned, road accessible RC Gold Project (‘RC Gold’ or the ‘Project’) within the Yukon’s prolific Tombstone Gold Belt. DDRCCC-25-113 returned impressive results with up to 119.0 metres of 1.01 g/t gold returned from surface, including 10.7 m of 4.1 g/t gold and 1.2 metres of 24.8 g/t gold, confirming significant gold mineralization at the Contact Zone. Assays are currently pending for an additional three drill holes that were completed at Contact along with three holes that were completed at the adjoining Pukelman target (see Figures 2 and 3). Assays are also pending for an additional 46 diamond drill holes that have been completed across the Rhosgobel, Blackjack, Saddle, Eiger, Bear Paw and MayQu targets. Approximately 32,000 metres of diamond drilling has been completed across the RC Gold Project this year.

CONTACT-PUKELMAN TARGET

In 2025, Sitka completed six diamond drill holes totalling 2,172 metres at Contact and three diamond drill holes totalling 1,876 metres at Pukelman (see Figure 2). Drilling intersected broad intervals of strongly altered metasediments cut by several quartz monzonite, and biotite-feldspar porphyritic dykes, along with abundant, cm scale, sheeted quartz veins. Visible gold was observed in the sheeted quartz veins and was often associated with arsenopyrite, bismuthinite, and minor scheelite (see Figures 3 and 4).

Sitka’s 2025 drill program was designed to expand the mineralized footprint of the Contact zone, test the zone with oriented diamond drill core to better understand controls on the mineralization and test the linkage between the metasedimentary and intrusion hosted mineralization of the Contact and Pukelman zones. The Contact zone was previously drilled in 2010 and 2011 with 1,660 metres in 12 holes of reverse circulation drilling and 254 metres in 2 holes of diamond drilling and encountered significant mineralization in quartz veining within metasedimentary rocks up to 450 metres south of the Pukelman intrusion. Current drilling to date has traced gold mineralization across a lateral extent of approximately 900 metres x 650 metres and from surface to a depth of approximately 430 metres.

* While visible gold observations are very encouraging and confirm the presence of gold mineralization, they are not intended to imply potential gold grades. Gold assays will be published after they are received from the lab for mineralized intervals in which visible gold particles were noted.

Quality Assurance/Quality Control

On receipt from the drill site, the HTW/NTW-sized drill core was systematically logged for geological attributes, photographed and sampled at Sitka’s core logging facility. Sample lengths as small as 0.3 m were used to isolate features of interest, otherwise a default 2 m downhole sample length was used. Each sample is identified by a unique sample tag number which is placed in the bag containing the core to be assayed. Core was cut in half lengthwise along a predetermined line, with one-half (same half, consistently) collected for analysis and one-half stored as a record. Standard reference materials, blanks and duplicate samples were inserted by Sitka personnel at regular intervals into the sample stream. Bagged samples were placed in secure bins to ensure integrity during transport. They were delivered by Sitka personnel or a contract expeditor to ALS Laboratories’ preparatory facility in Whitehorse, Yukon, with analyses completed in North Vancouver.

ALS is accredited to ISO 17025:2005 UKAS ref. 4028 for its laboratory analysis. Samples were crushed by ALS to over 70 per cent passing below two millimetres and split using a riffle splitter. One-thousand-gram splits were pulverized to over 85 per cent passing below 75 microns. Gold determinations are by fire assay with an inductively coupled plasma mass spectroscopy (ICP-AES) finish on 50 g subsamples of the prepared pulp (ALS code: Au-ICP-22). Any sample returning over 10 g/t gold was re-analyzed by fire assay with a gravimetric finish on a 50 g subsample (ALS code: Au-GRA21). In addition, a 51-element analysis was performed on a 0.5 g subsample of the prepared pulps by an aqua regia digestion followed by an inductively coupled plasma mass spectroscopy (ICP-MS) finish (ALS code: ME-MS41).

About Sitka’s Flagship RC Gold Project

Sitka’s 100% owned RC Gold Project consists of a 431 square kilometre contiguous district-scale land package located in the heart of Yukon’s Tombstone Gold Belt. The project is located approximately 100 kilometres east of Dawson City, which has a 5,000 foot paved runway, and is accessed via a secondary gravel road from the Klondike Highway which is usable year-round and is an approximate 2 hour drive from Dawson City. It is the largest consolidated land package strategically positioned mid-way between the Eagle Gold Mine and the past producing Brewery Creek Gold Mine.

The RC Gold Project now has pit-constrained mineral resources that are contained in two zones: the Blackjack and Eiger gold deposits with 1,291,000 ounces of gold in 39,962,000 tonnes grading 1.01 g/t gold in an indicated category and 1,044,000 ounces of gold in 34,603,000 tonnes grading 0.94 g/t in an inferred category at Blackjack and 440,000 ounces of gold in 27,362,000 tonnes grading 0.50 g/t gold in an inferred category at Eiger. These resource estimate numbers are supported by the recently updated technical report for RC Gold, prepared in accordance with NI 43-101 standards, entitled ‘Clear Creek Property, RC Gold Project NI 43-101 Technical Report Dawson Mining District, Yukon Territory’, prepared by Ronald G. Simpson, P. Geo., of GeoSim Services Inc. with an effective date of January 21, 2025. This report is available on SEDAR+ (http://www.sedarplus.ca) and on the Company’s website (www.sitkagoldcorp.com).

Both of these deposits begin at surface, are potentially open pit minable and Initial bottle roll metallurgical testing confirmed the non-refractory characteristics of the gold mineralization and returned gold extraction rates averaging around 85%. Further metallurgical testwork in 2024 returned recoveries ranging from 77.6 to 93% for gravity followed by cyanidation.

For the purposes of the current resource model, it is assumed that a likely mill flowsheet would consist of a gravimetric, flotation, and cyanidation circuit.

The company has now completed 165 diamond drill holes for a total of 59,770 metres across the Clear Creek Intrusive Complex (CCIC), and an additional 3 holes for 858 metres in the May-Qu Intrusion. Drilling continues to outline higher grade mineralization at all zones including hole DDRCCC-24-068 at Blackjack which intersected 678.1 metres of 1.04 g/t gold starting from surface (see news release dated October 21, 2024), and hole DDRCCC-25-075 which intersected 352.8 metres of 1.55 g/t gold including 108.9 metres of 3.27 g/t gold and 45.0 metres of 4.52 g/t gold (see news release dated April 22, 2025). Drilling in 2024/2025 has resulted in the discovery of a new higher grade zone at Rhosggobel including hole DDRCRG-25-010 at Rhosgobel which intersected 235.9 metres of 1.11 g/t gold, including 40.0 m of 2.01 g/t gold and 10.0 m of 5.29 g/t gold, from surface (see news release dated September 18, 2025).

RC Gold Deposit Model

Exploration on the Property has mainly focused on identifying an intrusion-related gold system (‘IRGS’). The property is within the Tombstone Gold Belt which is the prominent host to IRGS deposits within the Tintina Gold Province in Yukon and Alaska. Notable deposits from the belt include: Fort Knox Mine in Alaska with current Proven and Probable Reserves of 230 million tonnes at 0.3 g/t Au (2.471 million ounces; Sims 2018)(1); Eagle Gold Mine with current Measured and Indicated Resources of 233 million tonnes at a grade of 0.57 g/t Au at the Eagle Main Zone (4.303 million ounces; Harvey et al, 2022)(2); the Brewery Creek deposit with current Indicated Mineral Resource of 22.2 million tonnes at a gold grade of 1.11 g/t (0.789 million ounces; Hulse et al. 2020)(3); the AurMac Project with an Indicated Mineral Resource of 112.5 million tonnes grading 0.63 gram per tonne gold (2.274 million ounces)(4) plus an Inferred resource of 280.6 million tonnes grading 0.60 g/t gold (5.454 million ounces)(4), the Valley Deposit, with a current Measured and Indicated Mineral Resource of 7.94 million oz gold at 1.21 g/t and an additional Inferred Mineral Resource of 0.89 million oz at 0.62 g/t gold(5), and the Raven deposit with an inferred mineral resource of 1.1 million oz (19.96 million tonnes at 1.67 g/t gold)(6). The QP has been unable to verify the information regarding the above resource estimations and the information is not necessarily indicative of the mineralization on the property that is the subject of the disclosure.
