PC Gold has announced significant discoveries from resource definition drilling at its fully owned Spring Hill Gold Project, situated in the Pine Creek goldfield of the Northern Territory of Australia.
The drilling programme revealed high-grade gold within the Hong Kong and Macau lodes, with visible gold identified in multiple drill-holes, some extending beyond 30m in mineralised zones.

The Spring Hill project aims to bolster confidence in its existing mineral resource estimate (MRE) while expanding its resource inventory through targeted exploration.
A total of 26 drill-holes for 7,137m have been completed beneath the planned open pit and within elevated grade zones.
Assay results from this initial phase include significant gold intersections such as 2.8m at 15.21 grams per tonne (g/t) gold from a 1.7m downhole and 31m at 1.92g/t gold from a 75m downhole.
As the current resource definition drilling programme nears completion, logging and cutting are under way on the final two holes.

By GlobalDataConcurrently, diamond drilling is shifting towards metallurgical and geotechnical analysis, with reverse circulation (RC) drilling resuming extension programmes at Macau Extension and Lasagne.
PC Gold’s exploration efforts began in November 2025, focusing on mineralisation immediately below the projected open pit within the Macau and Hong Kong lodes.
The programme has identified a high-grade link zone with visible gold, supporting potential upgrades of approximately 300m from inferred to indicated classification in future resource modelling.
While many assay results are still pending, visual assessments suggest consistency with earlier projections.
Approximately 5,100 samples from infill drilling at the Macau Extension lode and other resource definition holes are awaiting assay results.
Post-Christmas shutdown, two diamond drills remain active on-site, with an RC rig expected to return by February 2026.
It will complete infill drilling at the Macau Extension before moving on to phase two of the Lasagne lode and further north to additional targets.
PC Gold executive chair Ashley Pattison said: “We are very encouraged by the identification of what appears to be a new high-grade zone at Macau, together with close-to-surface visible gold at Hong Kong, located north of the current proposed pit shell.
“Since mid-2025, our drilling campaign has completed more than 16,000m of diamond and RC drilling. The success of our step-out exploration programmes late in 2025 has exceeded expectations and we are very excited with the discovery of a high-grade link zone within the inferred portion of the Macau and Hong Kong lodes providing particularly exciting results.”
