The Golden Triangle’s New New Thing
The Golden Triangle of northwestern British Columbia plays host to some of the resource sector’s most prominent names. Newmont and Teck are advancing Galore Creek through pre-feasibility, Seabridge Gold’s KSM is among the largest undeveloped gold-copper resources in the world while Skeena Resources is advancing Eskay Creek towards a final investment decision. Tudor Gold, Dolly Varden, Enduro Metals are also among the players operating here. Given the capital focused on the region it is hard to believe that there is any ground that has not been subjected to careful consideration. If compelling targets remained, someone would have found them by now, right?

Enter Oreterra Metals Corp. (TSX-V: OTMC) and its Trek South prospect - a 1.6 by 1 km porphyry copper-gold target seven kilometres from Galore Creek - that has never been drilled. Trek South was not so much overlooked as revealed by a retreating glacier that exposed the underlying bedrock over the past decade or two. In the midst of one of the resource sector’s most prolific exploration districts, Oreterra is exploring ground that is effectively the Golden Triangle’s own new new thing.
CEO Kevin Keough - whose career began with De Beers and Anglo American before a switch to building junior exploration companies - first encountered Trek South in late 2024 while trying to acquire it for a different company. That deal fell through. “The results of the work that had been done were quite exceptional in my view. I didn’t even have to study it very hard — it looked like a really exceptional porphyry prospect right away.”, Keough said.
Keough took over the CEO role in June 2025 and began a methodical restructuring, drawing on skills honed over a decade in investment banking and venture capital and a generation running public resource companies - settling debt, refreshing the board, consolidating the shares, focusing, rebranding. The March 2026 financing, the lid on which was raised several times from an initial C$6 million target to, ultimately, C$9.7 million following only a single day’s marketing, was the culmination. Oreterra now has no debt, roughly 53.5 million shares outstanding, and is positioned to complete a two-phase maiden drill program at the Trek South prospect in the fast-approaching field season.

Since Trek South was first identified in 2019, successive work programs have mapped pervasive porphyry-style epidote-garnet alteration overprinted by a greater-than-1 km-wide pyrite-quartz stockwork vein network, with visible copper minerals including chalcopyrite, chalcocite, bornite, malachite and azurite across exposed bedrock and in up-ice boulders. Assays have returned up to 1.7 g/t gold, 1.83% copper, and 257 g/t silver from vein samples, with molybdenum, tungsten, and tellurium adding to the system’s polymetallic nature. Numerous copper mineralized boulders sampled in 2025 have assayed as high as 8.8 g/t gold and 2.8% copper. “It’s quite unusual in B.C. to see a porphyry with this kind of exposure on surface. You’re standing on bare rock over about a kilometre, and you can actually see the alteration and veining — exactly what you want to see.”, Keough explained. A 2022 geophysical survey mapped a chargeability anomaly of 40 mV/v - indicating bulk sulphide mineralization - at least 850 metres long, 500 metres wide, and extending below 650 metres depth, coincident with a magnetic high and supported by a deep-running MT anomaly to at least 2 km depth. In total, Trek South shows four independent stacked geophysical signals in the same footprint.
Keough was involved with GT Gold, whose Saddle North copper-gold porphyry is in the same region, with similar coincident magnetic-IP geometry, but much less to see on surface than Trek South offers. The company was sold to Newmont in 2021 for C$456 million after spending C$13.6 million on Saddle North exploration and drilling just 42 holes. The parallels to Trek South are hard to ignore. Two phases of drilling are planned this summer: 9,250 metres across 16 holes, combined budget C$6.8 million, with contractors already engaged and two drills expected on-site in late July. Keough is candid about what the program cannot promise. Keough is optimistic about the program: “We know where the system is — it’s right there. The question now is what the intersection lengths are going to be, and what grades will be associated with them.”
Market geeks will be familiar with an old joke told at the expense of Eugene Fama and the efficient market hypothesis, in which two economists spot a $10 bill on the pavement. One moves to pick it up. The other stops him: “Don’t bother - if it were real, someone would have picked it up already.” Some might say the same about Trek South: if there were a potential major porphyry opportunity sitting just seven kilometres from Galore Creek, in a district home to Newmont, Teck, and Seabridge, surely someone would have already picked it up. But until not long ago, Trek South was under ice, hidden in plain sight. Today, Oreterra trades near a C$30 million market cap with C$9 million cash and no debt, a potential geological $10 bill in the midst of this well-studied mining belt. Given Trek South’s Golden Triangle location, results to date and the team behind Oreterra, investors may decide it is worth a closer look while waiting for summer drill results to test the thesis.
