The following is a short text from todays Cerrado Gold’s press release in which they provided further information on progress at Mont Sorcier. They have made significant progress drilling 17,000 metres of infill to update the resource to the Proven and Probable categories to provide a feasibility study by Q2, 2026. The portion of the text of the Cerrado press release as regards the Mont Sorcier project is presented below in its entirety.

Mont Sorcier Project Update

“At the Mont Sorcier high-purity iron project, all key workstreams continued to progress the feasibility study, and the Company completed an infill drilling program to update sufficient resources to the Proven and Probable categories. Over 17,000 metres were drilled with results to be incorporated into a new mineral reserve estimate to support the feasibility study, which is targeted for completion in Q2 2026.

The Bankable Feasibility Study aims to provide a detailed updated economic study on the potential for the project as highlighted in the previous 2022 NI 43-101 Preliminary Economic Assessment (“PEA”) that delivered a project NPV_8% of US$1.6 billion based upon iron concentrates grading 65% iron. As highlighted previously, new test work has now shown the ability to deliver a high-purity DRI-grade Iron concentrate product of over 67% iron, enhancing the projects position delivering a highly desired product to support growing demand from the Green Steel transition.

Cerrado is developing its 100% owned Mont Sorcier high-purity, high-grade, Direct Reduced Iron project, located on the traditional Cree territory of Eeyou Istchee James Bay in the municipality of Chibougamau. The Mont Sorcier project has the potential to produce a premium iron concentrate over a long mine life at low operating costs and low capital intensity. Furthermore, its high grade and high purity product facilitates the migration of steel producers from blast furnaces to electric arc furnaces, contributing to the decarbonization of the industry and the achievement of sustainable development goals.”
