High-Priority Drill Targets Identified at Star Range Silver-Antimony Project in Utah

Why It Matters

The discovery could boost U.S. domestic supply of strategic silver and antimony, metals critical for defence, electric‑vehicle and renewable‑energy technologies.

Key Takeaways

• IP survey revealed chargeability anomalies near known mineralisation
• Targets align with STAR‑01 magnetic anomaly and intrusive contact
• Surface samples showed up to 3,043 g/t silver
• Maiden drill program scheduled for Q2 2026
• Project supports US critical mineral supply chain

Pulse Analysis

Silver and antimony have moved beyond traditional precious‑metal roles, becoming essential inputs for defence electronics, electric‑vehicle batteries, solar photovoltaics, and 5G infrastructure. The United States has intensified its push for domestic sources to reduce reliance on imports, offering incentives for exploration and development of critical minerals. In this environment, geophysical techniques such as induced‑polarisation (IP) surveys are increasingly valued for their ability to pinpoint subsurface sulphide zones that often host high‑grade silver‑antimony mineralisation. Projects that can quickly translate survey data into drillable targets are therefore positioned to capture early‑stage value.

Diablo Resources’ recent 9‑km IP program at the North Star prospect identified multiple chargeability and conductivity anomalies that coincide with the STAR‑01 magnetic high‑ground and an intrusive‑sediment contact—structures historically linked to prolific silver systems in the western United States. Surface sampling that returned up to 3,043 g/t silver and 0.7 % antimony validates the geophysical signatures and suggests a potentially extensive, yet untested, sulphide envelope at depth. By defining three priority drill zones, Diablo can test both the deep‑seated anomalies and the high‑grade veins already exposed at surface, increasing the odds of discovering a sizable ore body.

The forthcoming Q2 2026 maiden drill campaign places Diablo among a limited group of junior explorers targeting domestic silver‑antimony resources. Successful results could attract strategic investors seeking exposure to metals tied to clean‑energy and defence supply chains, while also aligning with U.S. policy goals for mineral security. Pending permitting and logistical planning, the company’s flexible target suite offers room to adapt the drill program based on early hole results, a critical advantage in a competitive exploration landscape. If the drill holes confirm continuity, the Star Range project could become a cornerstone of the emerging American silver‑antimony sector.
