Surface assays deliver up to 880 g/t silver, 7.4% copper and 0.6% antimony as company advances toward first drilling in a Tier-1 US mining jurisdiction

Diablo Resources (OTCQB:DBORF)

UTAH, UT, UNITED STATES, January 15, 2026 /EINPresswire.com/ — Diablo Resources Limited (ASX:DBO; OTCQB:DBORF) has confirmed multiple high-grade silver-antimony-copper mineral systems at its 100%-owned Star Range Project in southwestern Utah, following the receipt of final reconnaissance rock-sampling results that extend known mineralised trends and define new prospect areas.

Recent surface sampling returned exceptional grades, including silver assays of up to 880 g/t (28 oz/t), copper up to 7.4%, gold up to 9.3 g/t, and antimony up to 0.6%, reinforcing Star Range’s potential as a US-based critical minerals project at a time of strengthening demand and constrained global supply.

The latest results confirm multiple polymetallic systems across the project area, with the North Star Prospect emerging as a priority drill target. At North Star, mineralised breccia and vein trends have now been defined over more than 3 kilometres, remaining open along strike and supported by high-grade silver, copper, gold and antimony at surface.

New prospect areas have also been identified, including:

>East Star, where skarn-style mineralisation returned peak results of 300 g/t silver, 1.4 g/t gold and 7.4% copper, with the majority of samples grading above 0.7% copper;

>West Star, which delivered silver values of up to 692 g/t alongside elevated gold; and

>Silver Gulch, where mineralised trends have now been traced over 900 metres, extending a system that has previously returned multi-kilogram silver values at surface.

Drill targeting is well advanced, with interpretation of airborne magnetic data nearing completion and the permitting process underway to support a maiden drilling program.

CEO Lyle Thorne commented:

“These latest results represent a pivotal step forward for the Star Range Project. We have successfully extended mineralisation at our key prospects and, importantly, identified entirely new zones such as East Star, West Star and Silver Gulch, confirming the project hosts multiple polymetallic systems prospective for silver, copper, and antimony.

North Star is rapidly taking shape as an incredibly exciting drill target. The combination of high grade surface results, extensive strike continuity and multiple mineralised styles gives us confidence in the scale potential of the system.

With geophysical interpretation nearing completion and further results pending from ongoing fieldwork, we are progressing steadily toward our maiden drilling program.”

The Star Range Project is located approximately 6 kilometres west of Milford, Utah, within a historically productive mining district that has hosted significant silver and copper production. The project benefits from excellent access to infrastructure, nearby operating and historical mines, and a skilled local workforce, supporting rapid advancement toward drilling.

The exploration update comes amid a strong outlook for the targeted commodities. Silver has surged more than 185% during 2025, copper prices have risen sharply on electrification and renewable energy demand, and antimony prices have reached record levels amid growing supply constraints.

Utah's overlooked antimony deposits offer a strategic investment opportunity amid global supply concerns. Trigg Minerals leads the charge in domestic production.

Utah may be best known for its copper and gold legacy, but hidden beneath its rugged terrain lies one of the most overlooked critical mineral opportunities in the US: antimony.

With global supply heavily concentrated in China and export restrictions tightening, Utah’s underexplored antimony deposits are gaining new relevance. For investors, this presents a timely and potentially undervalued opportunity to get ahead of a domestic supply chain revival, with early movers leading the way.

Once home to scattered historic antimony production, Utah is now re-emerging as a strategic hotspot for this essential element.

Antimony is increasingly recognized as a mineral of strategic importance due to its broad industrial and defense applications. Used in flame retardants, semiconductors, lead-acid batteries, military-grade alloys and solar energy systems, it plays a vital role in modern manufacturing and national security.

The US government lists antimony as a critical mineral, emphasizing the risk posed by concentrated foreign supply. Notably, China currently controls 83 percent of global production and 55 percent of reserves.

The geopolitical implications are significant. China has imposed export bans on antimony in recent years, raising alarm over Western access and increasing pressure on governments and industries to secure domestic sources. Growing demand, driven in part by renewable energy and military applications, underscores the urgency of diversifying supply.

Utah is globally known and well-established as a mining-friendly jurisdiction, with a history that dates back to the 19th-century silver and copper booms. Today, it remains a top-tier destination for mineral investment providing an ideal blend of regulatory clarity, skilled workforce and robust infrastructure — including highways, rail and energy networks.

The Utah Geological Survey has identified critical minerals as a top exploration priority, encouraging public-private collaboration and supporting legislative initiatives to streamline permitting processes and promote investment.

This pro-mining posture is timely, as the global push for critical mineral security has spurred renewed interest in Utah’s subsurface wealth — such as antimony, which has been documented in the state since the early 1900s.

Geologically, Utah sits at the convergence of highly prospective belts that stretch across eastern Nevada and western Utah. These belts are known for polymetallic mineral systems, including antimony associated with gold, silver and tungsten. Historic antimony production and showings have been identified in several regions, including Antimony Peak, Coyote Knoll, Beaver County, Thomas Range and Wah Wah Mountains.

Multiple exploration and early-stage development efforts are underway in and around Utah, reflecting growing recognition of the state’s antimony potential. Among these, Trigg Minerals’ (ASX:TMG,OTCQB:TMGLF) Antimony Canyon project stands out for its high-grade resource and potential to become a near-term domestic producer.

United States Antimony (NYSEAMERICAN:UAMY) is working to revive legacy production through its Bear River mill operations in southern Idaho, which historically sourced ore from Utah and surrounding districts. This project underscores the infrastructure advantage and historic production potential still present in the region.

Meanwhile, Perpetua Resources (TSX:PPTA,NASDAQ:PPTA) is advancing its Stibnite gold project in neighboring Idaho, notable for its large, integrated antimony-gold resource. Although geographically outside Utah, the project has spotlighted the strategic co-production of antimony in the broader Intermountain West.

Closer to home, historical antimony-rich areas such as Coyote Knoll and Antimony Peak in Utah continue to attract interest from juniors aiming to validate and expand on legacy mineralization through modern exploration. These projects, though in earlier stages, point to a pipeline of potential that complements advanced projects and reinforces the state’s growing role in the domestic antimony supply chain.

Trigg Minerals is a critical minerals exploration company strategically focused on high-grade antimony and gold assets. Known for its advanced portfolio in New South Wales, Australia — including the flagship Achilles Project — Trigg has expanded its footprint into the US with the acquisition of the Antimony Canyon project in Utah.

This move marks a significant strategic shift that positions the company to play a central role in the revitalization of domestic antimony production.

The Antimony Canyon project is regarded as one of the most prospective antimony assets in the US. Early data suggest it could host the highest-grade undeveloped antimony deposit in the country, giving Trigg a potential first-mover advantage in a market where the US has had no primary production in over two decades. Located in western Utah, the project benefits from proximity to existing transport corridors and infrastructure, enhancing the potential for a streamlined development pathway. This logistical advantage complements the state’s mining-friendly regulatory framework, which includes expedited permitting processes and potential eligibility for federal support under critical minerals programs.

Geologically, Antimony Canyon shares characteristics with Trigg’s Achilles Project, where the Wild Cattle Creek deposit in Australia has demonstrated a mineralized breccia system enriched in antimony, gold and tungsten. Trigg brings significant technical expertise from these analogous systems, which it can leverage in Utah to accelerate exploration and de-risk development. The company’s broader strategy is to establish a portfolio of scalable, high-grade antimony projects that can supply Western markets as geopolitical pressures continue to disrupt existing supply chains.

For investors, Trigg Minerals offers exposure to a scarce and strategically vital commodity, underpinned by high-grade geology, jurisdictional strength, and a clear path to becoming a near-term domestic supplier.

As the antimony market experiences supply shocks and pricing pressure due to Chinese export restrictions, Trigg’s entry into the US sector represents a compelling opportunity to invest in one of the few publicly traded companies poised to deliver critical mineral security in a North American context.

Utah offers a rare but essential combination of critical mineral prospectivity, supportive policy and infrastructure availability. In the current geopolitical climate, projects that can deliver reliable, domestic supplies of critical minerals — particularly those underpinned by strong grades and early exploration success — stand to benefit from government incentives and investor interest.

Investments in Utah-based antimony projects are further de-risked by transparent permitting processes, opportunities for federal funding, and a growing demand for local, ESG-compliant supply chains.

As such, early movers like Trigg Minerals are well-positioned to unlock long-term value for shareholders by capitalizing on the national push for critical mineral independence.

Red Mountain Mining Limited (ASX: RMX) has delivered highly encouraging results from its Red Mountain Mining Utah antimony project field programme, providing compelling evidence that the company may have secured access to one of America’s most promising antimony exploration opportunities. The results have been so positive that Red Mountain has immediately expanded its position by acquiring 19 additional claims, bringing the total project to 106 claims covering 8.9 km².

The Red Mountain Mining Utah antimony project directly adjoins American Tungsten and Antimony Ltd’s (ASX: AT4) Antimony Canyon Project, which boasts a conceptual Exploration Target of 12.8 to 15.6 Mt @ 0.75% to 1.5% Sb. Furthermore, this target contains between 96,000 to 234,000 tonnes of antimony metal. With AT4 commanding a market capitalisation of $152 million, Red Mountain’s adjoining position represents a significant strategic opportunity in the critical antimony space.

Field Mapping Confirms Geological Model and Mineralisation Potential

According to the announcement, Red Mountain’s US field team has completed comprehensive mapping across both claim blocks. Consequently, these results strongly validate the company’s exploration thesis. The mapping programme confirmed the presence of identical host rocks to those that contain mineralisation at the neighbouring Antimony Canyon Project.

The northern claims area revealed multiple indicators of a significant epithermal system. For instance, the geological team identified several key features that demonstrate the area’s potential:

• Widespread pervasive argillic alteration consistent with major hydrothermal activity

• Extensive silicification indicating intense fluid flow

• Localised oxidised breccias and quartz vein stockworks

• Northwest-trending fault control matching the structural framework at Antimony Canyon

These alteration zones are reported to be structurally controlled by the same fault splays that fundamentally control high-grade antimony mineralisation at the adjacent AT4 project. In addition, this suggests the Red Mountain Mining Utah antimony project may host similar mineralisation systems.

The southern claims area sits higher in the volcanic sequence but shows excellent indicators for concealed mineralisation at depth. However, the geological characteristics remain highly encouraging:

• Steep fault-controlled exposures of volcanic breccias and welded tuffs

• Pervasive silicification and iron-oxide alteration

• Strong fault-controlled quartz veining typical of epithermal systems

• Evidence suggesting the Flagstaff Formation extends beneath Red Mountain’s claims at shallow depths

The geological observations indicate Red Mountain’s southern claims represent the upper portion of an epithermal system. Consequently, this suggests excellent potential for antimony mineralisation at depth.

Satellite Technology Identifies Multiple High-Priority Targets

Red Mountain engaged Dirt Exploration to conduct advanced multispectral satellite analysis. Furthermore, the team used AT4’s 200 published rock chip samples to create a mineralisation fingerprint for the Antimony Canyon area. This fingerprint was then applied across Red Mountain’s project area to identify similar targets.

The Gas Targets and Mercury Vapour Targets show uniform distribution across the project area, including areas beneath cover. In addition, this indicates the potential for extensive buried mineralisation systems.

Significantly, targets in covered areas appear preferentially developed along mapped faults. This is consistent with the structural control model that governs antimony mineralisation in the district.

Understanding Epithermal Systems: Why This Matters for Investors

Epithermal systems are geological environments where hot, mineral-rich fluids circulate through rock fractures. Furthermore, these systems deposit valuable metals as they cool. These systems are particularly important for antimony exploration because they create the ideal conditions for high-grade stibnite formation.

Key characteristics that make epithermal systems attractive to investors include:

• High-grade potential – Can produce very rich ore concentrations

• Large-scale systems – Often extend over significant areas both laterally and vertically

• Predictable patterns – Geological signatures help identify drilling targets

• Multiple metals – Often contain gold, silver, and other valuable minerals alongside antimony

Red Mountain’s field work has identified multiple indicators of a major epithermal system. For instance, this includes the crucial structural controls that channel mineralising fluids and create ore deposits.

Strategic Positioning in America’s Critical Antimony Shortage

The Red Mountain Mining Utah antimony project gains additional significance from its location in the Antimony Mining District. This historically productive area was discovered in 1879 and operated until the 1960s.

The district’s north-south trending fault system connects to the regional Paunsaugunt Fault. Consequently, this creates a mineral highway that has already delivered high-grade antimony at AT4’s project.

Recent developments at the neighbouring Antimony Canyon Project underscore the district’s world-class potential:

• November 2024: AT4 reported exceptional sampling results including 29.4% Sb, 25.24% Sb, and 17.94% Sb

• Northern Extension Discovery: New high-grade zone returning up to 3.59% Sb, located just 1km north of Antimony Canyon

• December 2024: Regulatory approval received for 24-hole diamond drilling programme totalling 1,650m

The Northern Extension discovery is particularly significant as it demonstrates the strike extension potential. Furthermore, this extension runs both north and south from Antimony Canyon, directly supporting Red Mountain’s geological model.

The company’s systematic exploration approach is designed to rapidly advance the most promising targets through validated geological and geophysical methods.

Aggressive Exploration Programme Set to Unlock Value

Red Mountain has outlined a systematic exploration approach designed to rapidly advance the most promising targets. However, the programme follows a carefully structured methodology:

• High-priority surface mapping to follow up satellite-identified targets

• Sample collection and analysis of relevant structures and lithologies

• Ground-truthing of spectral anomalies

• High-resolution drone magnetics to locate undercover structural extensions

• Mapping of subsurface hydrothermal systems and direct sulfide detection

• Target refinement for drilling programmes

• RAB drilling for shallow target testing

• RC and diamond drilling for deeper targets

• Systematic testing of highest-priority geophysical and geological targets

This phased approach allows Red Mountain to efficiently prioritise its exploration spending. In addition, it systematically de-risks the project through multiple validation stages.

Investment Thesis: Why Red Mountain Deserves Attention

Red Mountain Mining presents a compelling investment opportunity in the critical antimony space. Furthermore, this opportunity is supported by several key factors:

Red Mountain’s Utah Antimony Project directly adjoins a $152 million antimony development. Consequently, this provides immediate validation of district prospectivity and geological continuity. The company’s 106 claims covering 8.9 km² offer significant exploration upside with multiple target types identified.

The field mapping programme has confirmed Red Mountain’s geological model, identifying:

• Identical host rocks to those containing high-grade mineralisation at Antimony Canyon

• Structural controls matching those that govern AT4’s mineralisation

• Epithermal alteration signatures indicating large-scale hydrothermal systems

• 300 prioritised targets from advanced satellite analysis

Antimony is classified as a critical mineral by the US Government. Furthermore, severe Western supply shortages are creating unprecedented market dynamics. Red Mountain’s US-based antimony projects position the company to benefit from government support and premium pricing.

Beyond Utah, Red Mountain holds additional antimony projects at Yellow Pine and Silver Dollar in Idaho. In addition, the company holds the Armidale Antimony-Gold Project in Australia, creating a diversified critical minerals portfolio.

Special Report: American Tungsten & Antimony is off to a flying start at its wholly owned Antimony Canyon project in Utah, with the first two holes from a maiden drilling campaign visually intercepting broad zones of antimony sulphide – otherwise known as stibnite.

Management believes the two holes at the Emma claim intersected the target mineralised horizon and confirmed the system’s geological continuity and significant width.

Both holes are visually interpreted to contain substantial zones of mineralisation, including massive to disseminated stibnite.

The first hole is interpreted to host a 19m thick main zone of massive to semi-massive stibnite, within a broader 42m alteration zone featuring disseminated stibnite mineralisation.

Management noted that the second hole intersected mineralisation with visually greater intensity, but cautioned that logging of the core is ongoing.

Curiously, this hole also intercepted minor arsenic sulphides, often regarded as key pathfinder minerals associated with high-grade antimony and gold systems.

Meanwhile, the group has commenced drilling of a third hole at Emma, designed to intersect the interpreted feeder system at about 150m depth.

managing director Andre Booyzen noted that “the visual confirmation of significant widths and the clear geological vectoring towards the east gives us high confidence as we target the feeder structure with Hole 3.”

Here, early visual inspection of the core in the third hole has identified stronger zones of orpiment and realgar when compared with the other two holes.

Management believes this to be an encouraging sign, suggesting that the drilling could be piercing the heart of a significant mineralised system.

Exploration upside

According to the company, Antimony Canyon could potentially become the first domestic source of antimony in the US.

It contains 20 patent mining claims covering some 375 acres. These include the Emma claim, which represents one of more than twenty historical workings scattered across the area.

In addition, the project tenure is surrounded by more than 360 unpatented lode claims that offer the possibility for expansion.

In essence, patented claims represent private land with mineral and surface rights owned by the company. Such attributes remove the need for federal land leases and could help accelerate the timelines for drilling and mine development.

At present, American Tungsten & Antimony is targeting exploration works at Emma.

However, the company believes the broader project tenure could host an extensive hydrothermal system with “district-scale” potential.

More specifically, its modelling suggests that mineralisation extends along a feeder system that links the historical mines such as Emma and Stebinite.

When combined, these areas are interpreted to form a single, extensive, and laterally continuous mineralised system.

“The extensive geophysics, surface sampling, and structural interpretation we completed before drilling gave us the confidence to target these specific zones, and the drill bit is now validating that model,” said Booyzen.

For now, the company has established an initial exploration target of between 6.1 and 6.9Mt at between 1.4% and 2.3% antimony, just for the patented claims.

Special Report: Specialist contractor Energold Drilling USA is preparing to carry out a 24-hole, 1650-metre diamond drilling program targeting antimony mineralisation at the Antimony Canyon project in Utah.

expects to receive the final regulatory approval for the program from the Utah Division of Oil, Gas and Mining once it lodges the required bond, scheduled for payment this week.

The company is targeting the “Salt n Pepper” tuff horizon which outcrops across much of the project’s private (patented) land claims.

TMG’s channel sampling produced results of up to 1.5m at 33.2% stibium (antimony) and 29.4% stibium from this target area.

Trigg Minerals managing director Andre Booyzen said securing the drilling permit was a significant milestone for the company, transitioning Trigg from explorer to active developer within the US critical minerals sector.

“Our strategy to initially focus on the patented claims is paying dividends, allowing us to leverage private land tenure to secure permits efficiently, avoiding potential federal delays,” he said.

“This is an exciting milestone for us, and this first phase of drilling will help inform our assessment of potential pilot-scale mining activities in 2026.

“We have a good relationship with the folks at the Utah Division of Oil, Gas and Mining and are appreciative of their support.”

Mobile drill rigs limit environmental impact

The drilling program will target two prospects in particular; the Little Emma prospect and the Gem prospect.

At Little Emma TMG will drill 21 holes in a close-spaced array to investigate the down-dip and feeder extensions of the Little Emma historical workings, where channel sampling returned 29.4% stibium.

At the Gem prospect, Trigg has planned three deeper holes of up to 120m, targeting structural feeders associated with the nearby Gem mine, where the company collected samples assaying at 17.94% stibium.

Booyzen said Trigg was pleased to appoint Energold Drilling, a top-tier contractor with a global reputation for working in challenging terrain, to complete the drilling program.

“Their use of heli-portable rigs greatly lowers our environmental impact,” he said.

“It allows us to access the high-grade 'Salt n Pepper' tuff targets above the canyon walls –areas that have historically yielded exceptional grades but have lacked modern drill testing.

“With site preparations finished and our logistics fully winterised, we are ready to commence drilling.

“We have also started planning and preparing the permit applications for the next phases of drilling on our patented claims.”

With demand for domestic sources of antimony in the US skyrocketing, and prices surging to in 2025, Trigg is developing the Antimony Canyon project within a particularly supportive environment.
