· Issued by Richmond Hill Resources PLC via PR Newswire

Summary by 6ix AI

Richmond Hill Resources PLC, a gold explorer focused on the Martello Gold Project near Dryden in north-western Ontario, Canada, said on November 4, 2026 that its drill crew has mobilised for drilling at Sakoose, the historic gold mine that is its immediate exploration focus.

Key details

  • The programme comprises nine diamond drillholes (holes drilled to recover solid rock core) for approximately 1,400 m from six drill pads.
  • Three holes are designed to provide modern verification of the main Sakoose vein at depths of approximately 80 to 150 m vertical.
  • The other six holes are aimed to test the vein's continuity between those positions, its down-plunge extension to the west, its extension beneath the historical workings at Shaft 1, the eastern limit of the workings, and a structural zone where the vein is interpreted to widen.

What’s still pending

  • The drill rig is expected to be in position in the week of November 4, 2026.

Richmond Hill Resources PLC (AIM: RHR, Frankfurt: V39), a gold exploration company focused on the Martello Gold Project near Dryden in north-western Ontario, Canada, announces that the drill crew have now mobilised and the drill rig is expected to be in position this week.

The programme comprises nine diamond drillholes for approximately 1,400 m from six drill pads. Three holes are designed to provide modern verification of the main Sakoose vein at depths of approximately 80–150 m vertical. The remaining six are aimed to test the continuity of the vein between these positions, its down-plunge extension to the west, its extension beneath the historical workings at Shaft 1, the eastern limit of the workings, and a structural zone where the vein is interpreted to widen.

About the Martello Gold Project

The Martello Gold Project is Richmond Hill Resources plc’s principal gold exploration asset, located near Dryden in north-western Ontario, Canada, within the Western Wabigoon Subprovince. The project comprises 202 mining claims covering approximately 6,750 hectares and hosts historic gold workings and multiple exploration targets.

The Company’s immediate exploration focus is the historic Sakoose gold mine, where past production and historical drilling provide evidence of high-grade gold mineralisation. Planned diamond drilling will test the continuity and geological controls of this mineralisation. Historical results do not establish a current mineral resource or demonstrate the economic viability of future mining.
