Orezone Gold (ASX:ORE) said confirmatory grade control drilling at the P17 zone at its Bombore gold mine in Burkina Faso, centered on the first six months of planned production from the zone, resulted in shallow and high-grade intercepts, according to a Thursday Australian bourse filing.

Drilling encountered intercepts of 7.5 grams per tonne grade of gold over 8 meters from 32 meters, as well as 5.3 grams per tonne grade of gold over 9 meters from 2 meters, the filing said.

The P17 Zone is a high-grade hard rock deposit outcropping at the surface located at the southern end of the Bombore mining lease. Mined ore from the zone is scheduled to be fed to the mill in early 2026 once commissioning is complete. The commissioning of the stage 1 hard rock plant is advancing, with the jaw crusher commissioned and a crushed ore stockpile established.

The company's shares jumped 4% in recent trading on Thursday.
