What Grande Portage Resources does

Grande Portage Resources Ltd. is a Vancouver-based, British Columbia-incorporated junior mineral exploration and development company focused entirely on advancing its 100%-owned New Amalga Gold Project (formerly the Herbert Gold project), located approximately 25 kilometers north of Juneau in Southeast Alaska. The project hosts indicated mineral resources of 1,438,500 ounces of gold at 9.47 g/t Au and inferred resources of 515,700 ounces at 8.85 g/t Au, materially above average industry grade. The company is pursuing underground mining with an offsite processing strategy, under which ore will be barged through British Columbia to third-party overseas processing facilities, lowering pre-production capital intensity.

The company's business model is single-asset, commodity-based, and pre-revenue. It generates no operating revenue today and targets commercial production around 2031; pricing is set by global gold markets rather than the company. Capital formation has been executed via multiple non-brokered private placements, warrant exercises, and a June 2026 binding strategic partnership with Ocean Partners UK Limited that includes a C$6 million equity investment at an 80% premium, a US$25 million construction loan facility, and an offtake agreement covering up to 100% of gold production for the first seven years of commercial operation. Eric Sprott is the largest shareholder at approximately 19.9%, with Ocean Partners becoming the second-largest shareholder post-transaction.

Grande Portage trades on the TSXV (GPG), OTCQX (GPTRF), and FSE (GPB), and has filed a positive NI 43-101 Preliminary Economic Assessment showing a US$979 million pre-tax NPV(5%), 69% pre-tax IRR, US$254.8 million pre-production capital expenditure, and a US$1,408 per payable ounce all-in sustaining cost at a base case gold price of US$3,200/oz. The project is forecast to produce 1.05 million ounces of gold over a seven-year mine life. Customer concentration is effectively total on Ocean Partners during the initial production period, and the principal value-creation path is successful construction, permitting, and ramp-up to commercial production.
