Gold’s Next Supply Source - Old Waste Rock
With gold still above $4,500 despite a sharp weekly pullback, junior miners are finding that yesterday’s waste dumps are today’s viable ore bodies - and one Vancouver Island project shows exactly how the economics have shifted.
What to know
-
Sasquatch Resources is targeting historic waste rock at British Columbia’s Mount Sicker mine, where grades of around 2 g/t gold could be economically processed using modern ore sorting technology.
-
Gold at $4,574.90 per ounce - even after an 8.4% weekly decline - makes previously uneconomic legacy material viable for recovery.
-
The project doubles as environmental remediation, addressing acid rock drainage from over a century of abandoned mine waste on Vancouver Island.
What happened
Sasquatch Resources, a junior explorer listed in Canada, is advancing plans to reprocess historic waste rock at the Mount Sicker mine on Vancouver Island, British Columbia. The site - which saw copper and gold production as far back as the early 1900s - has sat dormant for decades, leaving behind piles of sulphide-bearing waste rock that leach acid into local waterways.
The company’s approach centres on modern ore sorting technology to separate gold-bearing material from barren rock. Preliminary sampling suggests grades in the range of 2 g/t gold within the waste dumps. At current spot prices of $4,574.90 per ounce, that grade translates to roughly $290 of gold per tonne of material - a figure that comfortably clears the economics for a sorting and processing operation with minimal drilling or underground development costs.
Silver recovery is also part of the equation. With silver trading at $69.66 per ounce and the gold-silver ratio sitting at 65.7, any polymetallic credits from the historic copper-gold-silver mineralisation at Mount Sicker add meaningful value to the project.
Who’s involved
Sasquatch Resources is a micro-cap junior - the kind of company that rarely moves the needle on global supply. But it represents a growing class of operators targeting legacy mine sites where the ore has, in effect, already been mined and stockpiled. The capex profile is fundamentally different from a greenfield discovery: no lengthy permitting for new underground workings, no years of feasibility studies on virgin ground.
British Columbia’s provincial government is a key stakeholder here. The province has been tightening environmental standards around abandoned mines, and projects that combine resource recovery with remediation sit in a regulatory sweet spot. For the BC government, having a private company clean up acid rock drainage at no public cost - while generating tax revenue and employment - is an attractive proposition.
Ore sorting technology providers, including firms like TOMRA and Steinert, are the enablers. Sensor-based sorting has matured rapidly over the past five years, allowing operators to reject waste rock before it enters the mill. For a project like Mount Sicker, this means processing only the highest-grade fraction and dramatically reducing tailings.
Why it matters
Elevated precious metals prices are reshaping what counts as a viable deposit. Two grams per tonne of gold in waste rock would have been laughable economics at $1,200 gold. At $4,500-plus, it is a real project.
This dynamic is playing out across the mining sector. From tailings reprocessing in South Africa’s Witwatersrand to heap leach operations on old Nevada dumps, the sustained price environment is unlocking a secondary supply pipeline. It will not replace primary mine output - global gold mine production runs around 3,500 tonnes annually - but it adds incremental ounces at a time when new major discoveries are increasingly rare.
The environmental angle is not window dressing. Legacy mine pollution is a genuine liability across British Columbia and the wider Pacific Northwest. If the economics of remediation-plus-recovery hold up at Mount Sicker, it creates a template that could be replicated at dozens of similar sites across Canada and the western United States.
What happens next
The immediate catalyst is whether Sasquatch can deliver a resource estimate on the waste dumps and secure the necessary environmental permits. Timelines for juniors at this stage are measured in quarters, not weeks. More broadly, gold’s price floor matters. The metal has pulled back sharply - down 12.1% from its monthly high near $5,405 - and Fed Chair Powell’s speech later today could add volatility. A sustained drop below $3,500 would start to squeeze the margins on low-grade reprocessing plays, though projects like Mount Sicker remain comfortably economic above $4,400.
