Stage 2 Drilling Program to Expand 'Pencil Porphyry' Discovery at Goodrich

Great Plains Metals Corp. (GPS) announced the mobilization plan for its fully funded Stage 2 diamond drill program at the Goodrich copper-gold project in New South Wales, Australia. The 1,000-meter campaign targets the lateral and down-dip geometry of the "Pencil Porphyry" system, following up on the Stage 1 discovery hole GGDD004, which returned 128m at 0.47% CuEq.

Mobilization is scheduled for the end of October 2026, with anticipated completion ahead of schedule and potential Q1 2027 planning for further drilling. The release details four proposed holes (GRMDD001-004) designed to test the porphyry core, eastern boundaries, and shallow southern extensions.

Exploration License EL9243 has been renewed until August 2032, securing the 290 km² tenement package. The company remains in Stage 2 of its earn-in agreement with Godolphin Resources Ltd., aiming to increase its stake from 51% to 70% through A$1,000,000 in exploration expenditure and 500 meters of drilling.

Great Plains Metals Corp. (GPS) has moved into the execution phase of a previously disclosed earn-in and exploration plan, launching a Stage 2 program that was first outlined in July 2026 news releases. The initiative is fully funded and follows the logical progression of testing the lateral and down-dip extensions of the initial discovery.

The market was already aware of the planned 1,000-meter campaign and the associated earn-in milestones, meaning the announcement brings no new surprises or unexpected catalysts. Additionally, the renewal of the exploration license until 2032 provides long-term tenure security but serves as a routine administrative update. The impact is incremental and expected, aligning with the company's stated exploration roadmap.

Great Plains Metals Corp. is an exploration-stage company focused on copper, gold, and molybdenum projects in Australia. Its flagship Goodrich project is located in New South Wales, approximately 70 km northwest of Orange, within the prospective Lachlan Fold Belt. The company has identified a "pencil porphyry" system, characterized by unidirectional solidification textures (USTs) and disseminated chalcopyrite. Stage 1 drilling intersected a 128-meter continuous intercept of 0.34% Cu and 0.17 g/t Au.

The company previously completed the acquisition of the Everton Project in Victoria but disposed of it after drilling confirmed weaker-than-expected molybdenum mineralization. GPS also holds a 37.1% stake in Eversley Resources, focusing on IOCG and REE targets in South Australia.
