Descriptiontext

Great Northern Minerals Limited (ASX: GNM, OTCQB: GNMRF) is a pre-revenue mining exploration company headquartered in Perth, Australia, with a 125+ year corporate history dating to 1899. Originally incorporated as Gollin Wallsend Coal Company Ltd, the company underwent a strategic transformation in October 2019, rebranding and pivoting from coal to gold and critical minerals exploration. The company operates three exploration-stage projects: the Catalyst Ridge Project in California's Mountain Pass District targeting rare earth elements and antimony (214 lode mining claims, ~18 km²), the Iron Butte Project in Nevada's Battle Mountain-Cortez Trend with a JORC (2012) Inferred Mineral Resource of 480,000 oz Au and 11.5 million oz Ag (~465 hectares), and the Douglas Creek Project in North Queensland featuring a copper-gold porphyry intrusion-related gold system spanning 125 hectares.

The company's core technology is conventional mining exploration using geophysical characterization techniques including magnetic surveys, gravity surveys, induced polarisation surveys, and magnetotelluric surveys, combined with systematic geochemical sampling and JORC (2012) compliant mineral resource estimation. Its primary proprietary differentiators are detailed magnetic data processing and interpretation for REE-bearing carbonatite targeting, and the discovery/definition of the Douglas Creek IRGS deposit in early 2022.

The business model is pre-revenue capital raising through equity issuance on the ASX and OTCQB markets to fund exploration activities. The company has no commercial products or services, no pricing model, and no revenue streams. Its go-to-market motion is investor relations-focused — ASX announcements, corporate presentations, participation in mining conferences (Noosa, NWR, Brisbane), and digital channels (LinkedIn, X, YouTube). The de facto customer base is institutional and retail mining investors, with future potential offtake agreements for gold, silver, REE, and antimony production. Capital structure as of July 2026 comprises 493,613,693 ordinary shares, 247,171,829 unlisted options, and 48,000,000 performance rights, with a share price of $0.044 AUD.

Great Northern Minerals is a mining and exploration company focused on gold and critical minerals across Australia and the United States. The company's portfolio consists of three distinct mining projects: the Catalyst Ridge Project (REE and antimony in California), the Iron Butte Project (gold-silver in Nevada), and the Douglas Creek Project (copper-gold porphyry in Australia). These projects operate independently as exploration-stage assets rather than as a unified software platform or integrated product suite.

Discovery AlertGreat Northern Minerals Catalyst Ridge Discovery Spans 1.25km with Gold TargetsGreat Northern Minerals has confirmed and substantially extended its antimony discovery at the Catalyst Ridge Project in California, with the Antimony Gulch vein system now spanning 1.25 kilometres in length and surface silicification zones exceeding 40 metres in width. The exploration mapping identified a vertically zoned epithermal system with high-grade antimony (up to 7.1%), tungsten (0.4%), and silver (23.3 g/t) at surface, while geological modeling indicates significant gold-silver potential at depth in the Walker Lane Mineral Belt. The company is advancing toward drill testing following permit applications for a DDIP survey to detect sulphide mineralisation depth.MiningM&A Monday: Merger to search the deep-seasAmerican Ocean Minerals Corporation and Odyssey Marine Exploration have entered a definitive merger agreement valued at US$1 billion to create a joint deep-sea critical minerals research and resource extraction platform, trading on Nasdaq under the ticker 'AOMC'. The transaction includes a private placement raising US$150 million and builds on a previously completed $75 million pre-public financing by AOMC in February 2026, combining what the companies describe as 300 years of deep-sea expertise. Separately, Zinc of Ireland acquired Netherlands-based Metallon Clean Extractions BV for $4 million to gain access to two hydrometallurgical technologies targeting zinc leach residue processing and lead-acid battery recycling, while Great Northern Minerals finalized the $1.9 million cash divestment of its remaining interest in Golden Ant Mining.ABN NewswireEllis Martin Report: Antimony, Rare Earths and the Mountain Pass District - Mineralization at SurfaceIn a new edition of The Ellis Martin Report, host Ellis Martin interviews Greg Schifrin, President of Minx Corporation, about the growing importance of U.S. critical minerals supply chains, focusing on Great Northern Minerals' Catalyst Ridge Project near the Mountain Pass district in California. The discussion covers high-grade antimony identified at surface levels, a one-kilometer antimony-silver-gold structural trend, and the geological potential of the Mountain Pass rare earth corridor for strategic materials. The interview takes a geology-first approach to assess exploration opportunities and next technical steps without speculation or promotional language.ABN NewswireEllis Martin Report: Antimony, Rare Earths and the Mountain Pass District - Mineralization at SurfaceEllis Martin Report features an interview with Greg Schifrin, President of Minx Corporation, discussing the significance of antimony, rare earth elements, and the domestic U.S. critical minerals supply chain. The focus is on Great Northern Minerals' Catalyst Ridge Project in California, near the Mountain Pass district, highlighting high-grade antimony mineralization and geological exploration efforts.Small CapsGreat Northern Minerals to Expand Catalyst Ridge after Strong Antimony Returns from Rock-Chip SamplingGreat Northern Minerals (ASX: GNM) has reported a significant antimony discovery at its Catalyst Ridge project after surface sampling identified a quartz-stibnite vein extending up to one kilometre, with high-grade antimony assays returning up to 7.1% along with associated silver and tungsten values. The company has lodged applications to expand the project area to 20.48 square kilometres and plans further detailed mapping, surface sampling, and induced polarization surveys to define drill targets. Non-executive chair Eddie King said the discovery reinforces Catalyst Ridge's strategic potential and aligns with known deposits in the area.ABN NewswireEllis Martin Report Highlights Mountain Pass Context for Great Northern Minerals Limited (ASX:GNM)Great Northern Minerals Limited (ASX:GNM) featured in an Ellis Martin Report segment discussing the company's rare earth and critical minerals strategy amid growing U.S. demand for non-Chinese supply chains. The Mountain Pass mine in California, the only producing rare earth mine in the United States, serves as the geopolitical and commercial framework shaping opportunities for GNM's Australian exploration projects. The segment examined how companies aligned with North American supply chains may benefit as U.S. policymakers focus on diversifying critical mineral dependencies.YouTubeGreat Northern Minerals advances US rare earth strategyGreat Northern Minerals has completed initial fieldwork at its Catalyst Ridge Project in California and signed a licensing option agreement with the University of Arizona to collaborate on rare earth flotation technology. The two-year sponsored research program aims to develop more efficient, lower-waste processing methods to reduce US reliance on Chinese technology for critical minerals. This strategic shift aligns with broader US-Australia cooperation in the sector, highlighted by an $8.5 billion agreement.MiningGreat Northern winds up rare earths-antimony acquisitionGreat Northern Minerals (ASX:GNM) has completed an acquisition of the Catalyst Ridge Rare Earth-Antimony Project, comprising 214 lode mining claims across four claim areas totaling 18km in the Mojave Desert, California. The company, with a market capitalisation of $14 million, intends to conduct exploration over the coming months with initial sampling results expected in mid-November. The acquisition aligns with a newly signed bilateral framework agreement between the US and Australia committing over US$1 billion each to support a US$8.5 billion pipeline of critical minerals projects.ThemarketbullRare earth rush: Acquisitions highlight growing demand for heavy rare earthsAcquisitions and exploration successes by junior mining firms such as Great Northern Minerals and Basin Energy have driven significant share price gains, highlighting intense investor interest in heavy rare earth supply chains near the U.S. Mountain Pass mine. This market momentum coincides with the U.S. Department of the Interior's draft 2025 Critical Minerals List, which prioritizes dysprosium and terbium to reduce reliance on Chinese imports.
