Pre-IPO gold exploration · Papua New Guinea & Queensland
Four gold systems, each prospective for the same reason it’s still available.
Epi Resources holds four early-stage gold projects across two established provinces. In every case, historical explorers tested the wrong level with the wrong methods, then walked away on a low-1990s gold price — not on the geology. None has ever had a hole test the gold window.
The portfolio
Four independent systems, ordered by depth of exploration data.
From the most-worked ground to the true blank slate. Each carries a mapped hydrothermal gold system, historical high-grade surface gold, and a set of modern satellite-spectral targets — and each was left before it was ever properly tested.
Kairiru
An active epithermal system — breached caldera, hot springs and a steaming coastal platform. Forty years of work all went to the eroded north flank; the preserved southern flank has never been drilled or soil-sampled.
Mt Donald
A zoned porphyry-to-epithermal system around a Kennedy-age diorite — the family behind North Queensland’s ~40 Moz of intrusion-related gold. Granted, road-accessible, and never tested by a diamond hole.
Tanga
A sealed, still-hot system on the arc that built Lihir (>80 Moz) and Simberi (~8 Moz). 1986 drilling only tested the barren cap; Boang — the largest island, with the airstrip — was never even held.
Mussau
A volcanic core sealed under a Pliocene reef. The last operator mapped a buried mineralised system, then left on the gold price. Not one hole and not one geophysical line has ever been completed here.
Grades are peak historical surface samples, not resources. † Tanga’s 1986 drilling maxed at 0.231 g/t through the barren cap; the gold window is untested. ‡ Mussau’s 28.1 g/t is a single float boulder among eight barren samples.
The investment thesis
The same pattern, four times over.
Each project was read the same way — the historical record, the databases, the drill data and a satellite-spectral interpretation against one another for the first time. The same four findings recur, and together they explain both why the ground is prospective and why it’s still available.
Everyone tested the wrong level
Sampling and drilling concentrated on the eroded, capped or barren part of each system — not the narrow boiling horizon where epithermal gold is deposited.
The pathfinder suite was never run
The elements that locate an explorer within a system — Sb, As, Hg, Te, Se, Tl, Ba, Mo — were assayed rarely or, in places, never in any medium.
The drilling was never a real test
Holes were shallow, mis-oriented, partly or wholly unassayed, or absent — and whole islands were never even held under tenement.
Abandoned on price, not geology
The ground was relinquished when gold was under US$400/oz. At ~US$3,980/oz today, the cheap first test that was uneconomic then is worth doing now.
None of the four is a grade problem. All are method, coverage or timing problems — the kind a well-run, low-cost first pass corrects.
