Trek Metals has secured a district-scale greenfields gold and rare earths exploration opportunity in the Kimberley Region of Western Australia after securing the acquisition of an extensive portfolio previously part of Newmont
Exploration Pty Ltd’s (Newmont) global exploration portfolio.

Summary
The Christmas Creek Project, located south-west of Halls Creek, represents a previously unexplored, largely concealed district-scale gold and rare earths exploration opportunity, associated with a major continental-scale tectonic lineament intersection.
The Project covers a total area of 1,183km2 , all of which is covered by Heritage Access Agreements, with total exploration expenditure to date of ~$5.7 million.
The Project previously sat within Newmont’s suite of exploration projects, held under a joint venture
with Archer X Pty Ltd (Archer X). Under the previous joint venture and earn-in agreement, Newmont
successfully earned a 75% interest in the Project. Newmont subsequently relinquished that interest following a rebalancing of its global exploration portfolio, returning the Project to 100% Archer X ownership.

Archer X targeted the area asit believed it may be an extension of the prolific Granites-Tanami Orogen (Figure 1), exposed as a basement high, with metasediments in the area showing a correlation to the Tanami host sequences. Newmont’s Tanami mine, located in the Northern Territory, is one of global significance, with Proven and Probable Reserves of 5.7Moz, with an additional 4.2Moz in Resources (as at 31st December 2022, refer to Newmont news release from 23rd February 2023:
The Tanami mine has been owned and operated by Newmont since 2002, producing an average of 500koz of gold each year.
Four major prospects have been identified within the Christmas Creek Project area – Martin, Coogan, Zahn and Willis (Figure 2) utilising Newmont’s proprietary Deep Sensing Geochemistry (DSG) which has been developed to explore for mineralisation concealed under cover.
The presence of bedrock gold mineralization has been confirmed by drilling at Martin and Coogan, although both these prospects remain sparsely drill tested, in particular Coogan with drill lines approximately 1km apart. The strong gold surface anomalism at Zahn remains unexplained in drilling and there has been no drilling to date at the Willis Prospect.
Apart from the main prospect areas, Trek believes the project area has considerable additional exploration potential given there are several additional surface geochemical anomalies that have not been fully defined or tested. Of note is a large gold anomaly located about 12km to the south-west of Coogan along the same structural trend (Figure 5). This anomaly has been defined by very broadspaced (2 x 1km) geochemical sampling and extends over about 8km.

Trek believes that additional opportunities are present in the project area, such as the potential for rare earth element (REE) mineralisation, given the project’s proximity to the Cummins Range REE deposit.
The Cummins Range Project, owned by RareX Limited (ASX:REE), is adjacent to the project tenements in the south-east of the Christmas Creek Project. This is hosted by a weathered carbonatite in the Cummins Range Intrusive Complex, with an Inferred and Indicated Resource of 519Mt at 0.32% total rare earth oxides (TREO) and 4.6% P2O5, for a contained 1.6 million tonnes of contained TREO and 24 million tonnes of contained P2O5 (refer ASX:REE announcement 1 May 2023). Sampling conducted by Newmont indicates areas with elevated rare-earth elements (lanthanum, cerium and yttrium), typically highlighting resistate minerals such as monazite in alluvial regolith. To the east of the Project’s Zahn prospect, approximately 7km west of the Cummins Range Project, elevated REEs are coincident with elevated magnetics and could reflect carbonatite dykes.

Gold
Potential for a large-scale VMS base metal system.
Trek has been active at the Pincunah Project since 2020 with a drilling program completed in 2021 that highlighted the potential for a large-scale VMS base metal system (refer ASX: TKM 13th October 2021). The drilling at VOG intersected multiple horizons of mineralisation and alteration, with highly anomalous zinc, copper and silver, plus multiple pathfinder elements indicating a very fertile volcanic environment.

Summary
Trek has been active at the Pincunah Project since 2020 with a drilling program completed in 2021 that highlighted the potential for a large-scale VMS base metal system (refer ASX: TKM 13th October 2021). The drilling at VOG intersected multiple horizons of mineralisation and alteration, with highly anomalous zinc, copper and silver, plus multiple pathfinder elements indicating a very fertile volcanic environment.
Subsequent to the drilling, Trek completed an airborne EM survey and extended surface geochemistry to cover the EM targets, with assay results confirming coincident EM and geochemical anomalies. The surface geochemistry results significantly upgrade the prospectivity of airborne EM conductive target ‘A’ (refer ASX: TKM 16th November 2021) as a compelling target along strike from the VOG discovery.
Figure 3: Classified surface geochemical data at Pincunah, highlighting the relationship with previously defined Valley of the Gossans Prospect and Champagne Pool, both situated along a geological boundary with a strong structural control.
Ongoing analysis of the surface geochemistry over ‘Conductor A’ has revealed a more compelling target with the element association consistent with a low temperature epithermal ‘cap’, with the refined target at the prospect renamed ‘Champagne Pool’. Defined by the combination of Zn-Hg-Te- (Fe-In), with low level gold, the Champagne Pool target is a discrete bullseye target that covers an area of 750m x 200m, with a halo of Hg grading out to lower temperature antimony.
Trek expects to commence drilling at Champagne Pool early in Q2 2024 with all permitting already in place with an approved POW from DMIRS and on-country heritage survey previously completed with the Nyamal over the proposed drill area and associated access.
