Pilbara Gold Limited (ASX:PGL) has reported extensional drilling results from its 2026 program at the 2.1 million ounce Mt York Gold Project in Western Australia's Pilbara region, confirming continuity of gold mineralisation along and beneath the 4.2-kilometre mineralised trend, with results returned from holes drilled significantly below the existing resource boundary.

Key Points

Extensional drilling at Main Hill returned 68m @ 1.00g/t Au from 347m, including 15m @ 2.56g/t Au from 357m (hole 26MYRCD086), and 44m @ 1.00g/t Au from 417m, including 5m @ 2.09g/t Au from 418m (hole 26MYRCD084)
Main Hill Extension extensional results include 5m @ 5.72g/t Au from 127m, including 1m @ 16.92g/t Au from 128m (hole 26MYRC116)
Infill drilling at Main Hill returned 42m @ 1.37g/t Au from 143m, including 9m @ 3.99g/t Au from 158m (hole 26MYRCD103), and 54m @ 1.01g/t Au from 254m, including 6m @ 5.06g/t Au from 302m (hole 26MYRCD096)
A new Mineral Resource Estimate, maiden Ore Reserve, and Pre-Feasibility Study are scheduled for completion during CY2027
Assay results remain pending for 27 drill holes, the vast majority from Main Hill Extension

Extensional Drilling Results at Main Hill and Main Hill Extension

Extensional drilling at Main Hill, targeting positions outside the current resource envelope, returned 68m @ 1.00g/t Au from 347m, including 15m @ 2.56g/t Au from 357m in hole 26MYRCD086. Hole 26MYRCD084 extended mineralisation over 180 metres below the 2026 resource pit shell, returning 44m @ 1.00g/t Au from 417m, including 5m @ 2.09g/t Au from 418m. At Main Hill Extension, hole 26MYRC116 returned 5m @ 5.72g/t Au from 127m, including 1m @ 16.92g/t Au from 128m. Hole 26MYRCD075 returned 15m @ 1.26g/t Au from 242m, including 1m @ 5.73g/t Au from 252m and 1m @ 5.04g/t Au from 256m. The gold resource remains open at depth along the entire 4.2-kilometre mineralised trend.

Infill Drilling Results Within the Existing Resource Envelope

Infill drilling at Main Hill, designed to improve resource classification confidence ahead of the next Mineral Resource Estimate, confirmed wide mineralised zones within the existing resource model. Hole 26MYRCD103 returned 42m @ 1.37g/t Au from 143m, including 9m @ 3.99g/t Au from 158m. Hole 26MYRCD096 returned 54m @ 1.01g/t Au from 254m, including 6m @ 5.06g/t Au from 302m. Hole 26MYRCD105 returned 26m @ 1.77g/t Au from 142m, including 6.56m @ 5.70g/t Au from 153.44m. Additional infill hole 26MYRCD087 returned 24m @ 1.05g/t Au from 234m, including 8m @ 2.09g/t Au from 238m, and 4m @ 2.64g/t Au from 289m, including 2m @ 4.23g/t Au from 290m.

Pre-Feasibility Study and Mineral Resource Estimate Timeline

All results from the 2026 drilling program will be used to inform a new Mineral Resource Estimate for the Mt York Pre-Feasibility Study. The new Mineral Resource Estimate and a maiden Ore Reserve estimation are scheduled for completion during CY2027. Geotechnical drilling, metallurgical test work, process engineering, and design studies are stated as progressing. Drilling is now focused on deeper areas of Main Hill and Main Hill Extension to target further resource growth beyond the current 2.1 million ounce figure. Assay results remain pending for 27 drill holes, with the vast majority from Main Hill Extension, as extensional drilling continues at both Main Hill and Main Hill Extension.
