Resolution Minerals doubles size of Horse Heaven drilling and expands land package on encouraging early exploration

• Resolution doubles drilling program at Horse Heaven gold-antimony-tungsten project to up to 20 holes
• Company adds 600 acres to its exploration land package through 30 new federal mining claims
• Results pending from drilling, stream sediment, mapping and rock chip sampling programs

Special Report: Resolution Minerals will double the scale of its Phase 1 program at the Horse Heaven gold-antimony-tungsten project in the Perpetua-Horse Heaven region in Idaho on the back of encouraging exploration results.

An amendment to its Plan of Operation from the US Forest Service that will push its drilling season beyond the current scheduled end date of 30 September 2025 for around a month.

That will allow Resolution Minerals (ASX:RML) to drill an additional eight to 10 holes, effectively doubling the ongoing program to an estimated 18 to 20 holes totalling ~5490m.

All drilling from October 1 will be conducted using a reverse circulation rig that has already been secured to replace the diamond rig that will complete operations as planned on September 30.

Separately, the company has also increased its exploration footprint by 600 acres to 14,580 acres, or about 59km2, by filing paperwork to acquire an additional 30 federal lode mining claims.

“This Amendment is a significant development for Resolution and its shareholders,” chief executive officer of US operations Craig Lindsay said.

“We have now secured a material extension of our Phase 1 drill program, including more metres and more holes, and increased our land package to cover additional areas of potential mineralisation.

“We are deeply appreciative of the willingness of the US Forest Service to work with us to help extend our drill program, which will allow us to double our expected footage, which will generate a significantly higher level of drill data to guide next season’s program, future resource estimates and permitting for an expanded exploration program.”

Phase 1 drilling

RML is currently on its ninth hole with 2231m of drilling completed to date at the Golden Gate target.

While the company has only just submitted samples from the first three holes for assaying, observations of the drill core have revealed very similar textures to that of the neighbouring $3 billion Stibnite gold project held by Perpetua Resources.

These suggest a kinship to the Stibnite project, which has secured development approval and is in line for a government loan owing to the strategic value of its antimony resources.

Adding interest, tungsten, a metal previously produced in the area but not assayed for in recent work, has now been confirmed through UV light analysis.

Recent rock chip sampling that returned antimony values as high as 49.8% Sb, and 1,420 g/t Silver, has also expanded the Golden Gate target to 3km by 0.5km.

Besides drill results, RML is also expecting results from other programs including a stream sediment program, as well as an ongoing mapping and rock chip programs.
