Resolution Minerals receives US Forest Service approval for Phase 1 drilling
Golden Gate Ridge to be the primary focus of antimony, gold, and tungsten targeting
Acquisition milestone achieved with vendor exercising project ownership option
Resolution Minerals Ltd (ASX:RML) has moved closer to launching a significant exploration program at the Horse Heaven Project in Idaho, United States, after receiving Plan of Operations approval from the US Forest Service. The company, part of the ASX 200, is preparing for drilling to commence in August.
The newly approved plan permits up to 57 drill holes from 19 sites, strategically positioned along existing roads. The focus will be on uncovering deeper sulphide mineralisation containing antimony, tungsten, and gold, especially in underexplored zones beyond historic shallow oxide targets.
Golden Gate Ridge to Lead Exploration Strategy
The Phase 1 campaign will begin at the Golden Gate target, where past exploration had concentrated on near-surface oxide gold with limited attention to critical metals. Historical drill campaigns in the area did not evaluate antimony or tungsten, leaving substantial mineralisation untested at depth.
Resolution’s new exploration plan is set to examine disseminated gold and associated critical elements along a broad mineralised fault zone. The Golden Gate Fault Zone spans several kilometres and has recorded past activity in both open-pit and underground formats, particularly for tungsten.
New Drilling to Uncover Untapped Depths
With modern assay techniques and a revised geological model, the campaign is poised to revisit targets that previous explorers overlooked. The company’s Phase 1 effort will involve thousands of feet of core drilling, with the aim of identifying mineral continuity beneath previously tested horizons.
Resolution’s US Operations CEO stated that this will be the first new drilling at Horse Heaven in over thirty years and expressed optimism about its alignment with national strategies to boost domestic supply of critical minerals.
Acquisition Progress Strengthens Project Position
A key milestone in the Horse Heaven acquisition has been reached with vendor 1503571 B.C. exercising its option to acquire full ownership of 1262446 B.C. Ltd. This subsidiary directly owns the project via Horse Heaven Holdings Inc. This action satisfies one of the three core conditions outlined in Resolution’s acquisition pathway.
Remaining steps include shareholder approval at the General Meeting scheduled later this month and completion of standard due diligence. These developments align with Resolution’s timeline to secure full ownership before the anticipated multi-phase drilling program.
Corporate Developments Include Escrow Releases
Alongside operational milestones, Resolution has announced adjustments to share and option escrow arrangements. Several tranches of shares and options will be released from voluntary escrow during July, in accordance with Listing Rule 3.10A.
This includes fully paid ordinary shares and quoted RMLOC options, as well as the expiration of a significant volume of RMLO options. These changes reflect the company’s transition into a more active project phase and support its ongoing advancement strategy.
