The Trek claims cover one of the few known porphyry Cu-Au occurrences in this part of the Golden Triangle not held by the Galore Creek Mining Corp. (GCMC). Work on Trek North was suspended after 2011 when the Galore Creek development project was halted due to an upward re-estimation of the capital costs. The owners of GCMC, now Teck and Newmont, have resumed work on the project in the past few years and it is currently in the pre-feasibility study stage. If a decision is made to proceed with development of a mine, GCMC will complete a mine access road and a slurry pipeline from the deposit(s) across the Trek claims to the mill site 11 km east of Trek. The economics of any mineralized zone on the Trek claims would then be greatly enhanced.
The Trek North zone was partially defined by 36 holes before work was suspended in 2011 and it is still largely open along strike and down-plunge to the north and northeast. Mineralization is associated with a series of monzonite dykes and appears to have precipitated along favourable sub-horizontal contact zones between several andesite units. A non-NI 43-101 compliant resource model completed in 2010-11 outlined various tonnage and grade scenarios, e.g. 40.8 MT @ 0.67 AuEq oz. Portions of the deposit are considerably higher grade, e.g. drill hole TRK-08-01 intersected 131m @ 0.6% Cu, 0.39 g/t Au and 8.5 g/t Ag, and there may be opportunities to carve out smaller tonnage, higher-grade sections.
The Trek South zone was discovered in 2019-2021 after a local glacier and icefield receded, exposing a ~1 km wide zone of strong epidote (propylitic) alteration overprinted by a stockwork of quartz-pyrite veins with local Cu, Au and Ag mineralization. This area is one of the most topographically favourable on the Trek claims as it is not particularly rugged and only moderately sloping. Further mapping and sampling is required to fully define this apparent porphyry system and an IP TM survey was completed in July-August 2022 in order to delineate any significant mineralization at depth; results are pending.
The TOE Zone is a historic Cu-Au-Ag showing interpreted as either a Kuroko type or an Eskay Creek type VMS (massive sulphide) occurrence. In spite of the high grade assays returned from brief sampling programs over the years (e.g. 4.5 g/t Au, 1,965 g/t Ag, 3.8% Cu, 2.27% Pb, >1% Sb and 2.9% Zn in 2006), this >200 m wide prospect has not yet been mapped in sufficient detail or subject to any ground geophysics or diamond drilling. A field visit in 2021 confirmed the presence of mineralized, pyritic felsic horizons up to 4 m wide along with broad zones of pyritic metasediments. The showing is well exposed in an escarpment and trends southward under glacial till. An initial program of detailed mapping and sampling is required here, followed by ground geophysical surveys and diamond drilling if warranted by the results.
The Trek property is one of Romios two highest priority projects in the Golden Triangle (along within the JW). It hosts not only Trek North, one of the few porphyry Cu-Au deposits in the area not owned by GCMC, but the newly discovered Trek South prospect which displays fairly consistent porphyry-type alteration and sporadic mineralization across a 1 km width in a reasonably accessible area close to the proposed Galore Creek mine access road and mill. Numerous high-grade Au-Ag-base metal occurrences occur between Trek North and South, most of which have seen no significant exploration for >25 years. These include the >200 m wide TOE Au-Ag-Cu-Zn-Pb-Sb VMS prospect, the Tangle, Gully, Silver Standard and East Zones. Re-mapping and sampling of these prospects in light of modern ore deposit models and the discovery of the Trek South porphyry system nearby may well upgrade the potential of these showings.
