PC Gold (ASX:PC2) has reported an 84% increase to its Spring Hill Gold Project mineral resource estimate (MRE) in the Northern Territory, bringing the total to 43.6 million tonnes (Mt) @ 1.10 grams per tonne gold (Au) for 1.51 million ounces (Moz).
The updated MRE, delivered at a 0.50g/t cutoff grade, incorporates 25,900m of additional drilling completed between October 2025 and April 2026. Indicated resources, in particular, have grown by 136% to 28.8Mt @ 1.10g/t Au for 1Moz, which represents 66% of the global resource.
PC Gold says the estimate also incorporates a maiden Link Zone domain resource of 1.12Mt @ 5.37g/t Au for 193,500 ounces, including 690,000 tonnes at 5.16g/t Au for 114,500 ounces in the indicated category.
Executive Chair Ashley Pattison says the rapid expansion has generated a global resource increase of 77,000 ounces per month since listing, with the indicated component comprising 66% of the global resource.
She also highlights the potential of the newly discovered Link Zone:
“[The Link Zone] has the potential to provide a second higher grade underground feed source operating alongside the proposed open pit and will now be evaluated as part of the Prefeasibility Study,” Pattison says.
PC Gold notes that mineralisation demonstrates continuity, averaging 2,594 indicated resource ounces per vertical metre in the top 365m, and remains open along strike and at depth.
The interim MRE covers less than 15% of the known geological strike length, excluding several ‘high-grade’ intercepts logged after the April cutoff date.
Key assay results outside the current MRE include 10m @ 4.51g/t Au from 161m in the Main Zone South; 113m @ 1.14g/t Au from surface, including 18m @ 4.62g/t Au from surface at Hong Kong; and 22m @ 2.60g/t Au from 164m at Hong Kong Footwall.
A 40,000m reverse circulation and diamond drilling program is currently underway, with PC Gold intending to deliver both a Prefeasibility Study and an additional MRE update in late Q4 2026.
PC Gold is a gold explorer and developer focused on its flagship Spring Hill Project in the NT.
