Resolution Minerals ASX:RML has completed one-third of a planned 13,700-metre drilling program to test extensions to the gold and tungsten mineralisation at its Horse Heaven project in the US.

Sixteen diamond core holes have been drilled at the Golden Gate South prospect by two on-site rigs for a total 4,470m at an average depth of 279m.

Core from each hole has been inspected to identify scheelite (a primary tungsten ore mineral) and two large batches of samples have been despatched for multi-element analysis.

Resolution’s campaign aims to define the scale and extent of gold mineralisation at the Golden Gate South and Golden Gate North targets, explore a broad tungsten anomaly in soil samples at Golden Gate South, and extend tungsten mineralisation around previous mine workings at the historic Golden Gate mine.

Historical Exploration

Golden Gate is located within the Horse Heaven antimony-tungsten-gold-silver project in Idaho, which sits immediately adjacent to the recently-permitted Stibnite gold project owned by Perpetua Resources.

Tungsten exploration and development at Golden Gate began in the late 1940s, with open pit mining commencing in the early 1950s and ore initially processed at the Stibnite mine, mill and smelter until its closure in 1952.

The area was most recently mined in 1980, with composite samples from stockpiles held at Resolution’s recently acquired Johnson Creek mill site returning assays of up to 1.85% tungsten trioxide.

DIBC Membership

Resolution’s antimony-tungsten strategy received a boost last month when the company was admitted as a member of the US defence industrial base consortium (DIBC).

Membership gives access to a range of supply chain initiatives and funding opportunities targeting the critical metals sector.

It also offers opportunities to collaborate with government agencies, industry participants, research institutions, and other organisations involved in strengthening domestic critical mineral supply chains.

Resolution believes Horse Heaven is ideally positioned to contribute to the development of domestic sources of critical materials.
