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, has announced the mobilisation of its drill crew at the historic Sakoose gold mine. The company states the drill rig is expected to be in position this week, marking a tangible operational milestone in its current exploration programme. The announcement was classified as inside information under the UK Market Abuse Regulation, underscoring its material relevance to investors monitoring progress at the AIM-listed junior miner.

Key Points

  • Richmond Hill Resources PLC (AIM: RHR, Frankfurt: V39)
  • The drill crew has mobilised and the rig is expected to be in position this week at the Sakoose gold mine within the Martello Gold Project
  • Nine diamond drillholes planned for approximately 1,400 metres across six drill pads; three holes target vein verification at 80–150 metres vertical depth
  • Investors should watch for drill results and any update on mineralisation continuity along the Sakoose vein

Nine-Hole Diamond Drilling Programme Targets Sakoose Vein Continuity and Down-Plunge Extensions

The planned programme comprises nine diamond drillholes totalling approximately 1,400 metres, drilled from six separate pads. Three of the holes are designed to provide modern verification of the main Sakoose vein at vertical depths of approximately 80 to 150 metres. The remaining six holes are intended to test the vein's continuity between known positions, its down-plunge extension to the west, its extension beneath historical workings at Shaft 1, the eastern limit of those workings, and a structural zone where the vein is geologically interpreted to widen — a potentially significant target for high-grade mineralisation.

Martello Gold Project Covers 6,750 Hectares Across 202 Mining Claims in the Western Wabigoon Subprovince

The Martello Gold Project is Richmond Hill Resources' principal exploration asset, situated near Dryden in north-western Ontario within the Western Wabigoon Subprovince — a region with established geological prospectivity for gold. The project encompasses 202 mining claims covering approximately 6,750 hectares, hosting historic gold workings and multiple exploration targets. The company's immediate focus is the Sakoose gold mine, where past production and historical drilling have provided evidence of high-grade gold mineralisation. The company notes, however, that historical results do not establish a current mineral resource or confirm economic viability of future mining.

Sakoose Historic Workings Provide Geological Context but No Declared Mineral Resource Yet

Investors should note that whilst historical drilling and past production at Sakoose offer encouraging geological context, Richmond Hill Resources has not declared a current mineral resource estimate under any recognised reporting standard. The current drilling programme is aimed at better understanding the geological controls and spatial continuity of mineralisation. The company is at an early exploration stage, and outcomes from this campaign will be critical in determining whether further resource definition work is warranted. Key risks include uncertainties around exploration results, regulatory processes in Ontario, and the company's ability to execute its stated plans within budget and timeframe.
