Diablo Resources Identifies High-Priority Targets at Silver-Antimony Project

Diablo Resources Unlocks High-Priority Drill Targets at Silver-Antimony Project

Diablo Resources Limited (ASX: DBO) has delivered a significant exploration breakthrough at its 100% owned Star Range Silver-Antimony Project in Utah. A recently completed Induced Polarisation (IP) survey has identified three high-priority drill targets that align perfectly with exceptional surface grades and favourable geological structures at the Diablo Resources silver-antimony project.

The IP survey results provide crucial validation for the untested North Star Prospect, where surface sampling has returned spectacular silver grades of up to 3,043 g/t Ag alongside significant antimony, copper, and gold values. With no historical drilling in the area, Diablo has positioned itself as the first-mover to test this highly prospective mineralised system.

Furthermore, this development represents a genuine exploration breakthrough in an area with exceptional discovery potential. The combination of high-grade surface mineralisation and validated geophysical targets creates compelling investment opportunities ahead of maiden drilling.

IP Survey Confirms Exceptional Exploration Potential

"We are very encouraged by the results of the IP survey completed at North Star. The survey has outlined clear anomalies of interest that coincide with known mineralisation and highly prospective geological settings, further reinforcing our view that the North Star Prospect represents a priority drill target," stated Lyle Thorne, CEO.

The 9 line-kilometre IP survey completed over four 200-metre spaced survey lines has outlined three distinct drill targets. These targets capitalise on both geophysical anomalies and geological prospectivity within the Diablo Resources silver-antimony project area.

Outstanding Surface Results Drive Target Selection

The IP survey targeted the STAR-01 magnetic anomaly, which correlates with extraordinary surface sampling results from vein and breccia-style mineralisation at North Star. The results demonstrate the exceptional grade potential of the project:

Strategic Drill Programme Takes Shape

Three Priority Drill Targets Identified

The survey has defined three priority targets for the upcoming maiden drilling campaign at the Diablo Resources silver-antimony project:

Hole 1: Testing a chargeability anomaly on section line 2, with adjacent surface samples exceeding 100 g/t Ag

Hole 2: Targeting a conductor anomaly associated with the granite-sediment contact on section line 2

Hole 3: Testing a chargeability anomaly potentially representing the northwestern extension of high-grade Ag-Sb-Cu-Au veins identified at surface

Understanding Induced Polarisation Surveys

Induced Polarisation is a geophysical technique that measures the electrical properties of subsurface rocks and minerals. When electrical current is applied to the ground, certain minerals (particularly sulphides) become temporarily polarised and release stored electrical charge when the current is switched off.

For investors, IP surveys excel at detecting sulphide mineralisation – exactly the type of deposit hosting silver-antimony mineralisation at the project. The technique can identify buried ore zones that don't outcrop at surface, significantly expanding exploration potential beyond visible mineralisation.

The survey specifications included 0.125 Hz interrupted square wave base frequency with 2-second on-off pulses and 16 stacks. Arizona-based TMC Geophysics completed the fieldwork, whilst data processing and interpretation was conducted by Resource Potentials Pty Ltd.

Strategic Location Within Proven Mining District

World-Class Neighbours Validate District Potential

The Diablo Resources silver-antimony project occupies a 5,242-acre landholding in southwestern Utah's prolific Basin & Range province. The project is strategically positioned near significant historical producers that demonstrate the district's exceptional potential:

Horn Silver Mine (15km northwest):

• One of the largest silver producers in United States history
• 17 million ounces of silver production until 1930
• 835,000 tons averaging 21.5 oz/t silver and 23% lead
• Production from single 20-acre mining claim demonstrates exceptional grade potential

Milford Copper Mine (9km north):

• Currently active open-pit copper operations
• Demonstrates ongoing commercial viability of the district

Infrastructure Advantages

In addition to its strategic location, the project benefits from established infrastructure that reduces development risks and costs:

• Power lines and gas pipelines near the southeast corner
• Union Pacific Railway access through nearby Milford township
• Maintained gravel roads providing direct property access
• 6km proximity to Milford town for logistics and services

Investment Thesis: First-Mover Advantage in Critical Minerals

Untapped Exploration Potential

Diablo's maiden drill programme represents a genuine first-mover opportunity in an area with no historical drilling. However, the convergence of several factors creates a compelling exploration story with significant discovery potential:

• Exceptional surface grades (up to 3,043 g/t Ag)
• Validated geophysical targets from professional IP survey
• Favourable geological setting along intrusive-sediment contacts
• Proven district mineralisation from nearby Horn Silver Mine

Critical Minerals Focus Aligns With Market Demand

Silver's dual role as both precious and strategic metal positions the Diablo Resources silver-antimony project advantageously within growing demand sectors. Strategic applications include:

• Defence systems and military equipment
• Electric vehicle components
• Solar panel manufacturing
• AI data centre infrastructure
• 5G telecommunications networks

Moreover, with the United States prioritising domestic critical mineral supply chains, Diablo's Utah-based project aligns with national strategic objectives.

"Silver is increasingly recognised both as a precious and strategic metal, with growing demand from defence systems, electric vehicles, solar panels, AI data centres, and 5G infrastructure. We are committed to participating in the United States' domestic efforts to secure reliable supplies of critical minerals," explained Lyle Thorne, CEO.

Geological Setting and Mineralisation Style

Basin & Range Province Characteristics

The Star Range Project lies within the structurally controlled Basin & Range province, characterised by block-faulted sediments comprising predominantly siliciclastics and carbonates of Palaeozoic to Tertiary age. This geological package consists of generally north-striking, east-dipping sediments that have been intruded and metamorphosed by granitic composition intrusive rocks.

For instance, the area includes porphyritic quartz monzonite intrusions that create the structural and chemical conditions favourable for mineralisation development.

Mineralisation Controls

The project area hosts numerous historical workings exploited primarily in the late 1800s for base and precious metals. Mineralisation occurs as:

• Structurally controlled replacement style (CRD) mineralisation
• Breccia vein systems along sediment contacts
• Skarn-style mineralised zones associated with intrusives

These mineralisation styles represent classical deposit types known to host significant silver-antimony deposits worldwide. Consequently, they provide strong geological precedent for the Diablo Resources silver-antimony project's exploration potential.

Upcoming Catalysts and Timeline

Q2 2026 Drilling Campaign

According to the company announcement, immediate next steps include several critical milestones:

1. Finalise drill programme planning and logistics coordination
2. Submit drill permit applications for Q2 2026 commencement
3. Continue regional exploration across broader Star Range Project
4. Review additional opportunities in US critical minerals sector

2026 Value Drivers

Technical Survey Specifications

Professional Survey Standards

The IP survey employed industry-standard methodologies designed to evaluate the mapped northwest-southeast intrusive-sediment contact for concealed mineralised zones. Survey parameters included professional-grade specifications:

• Configuration: Pole-Dipole (PDIP)
• Survey length: Approximately 9 line-kilometres over 4 survey lines
• Line spacing: 200 metres
• Station spacing: 100 metres
• Maximum N-value: N=16

The survey targeted chargeability or conductivity responses depending on several geological controls, including sulphide habit, alteration style, and presence of conductive minerals. The data processing produced 2D inversion models and 3D-gridded chargeability and resistivity datasets to depths exceeding 400 metres below surface.
