Terrain Minerals (ASX:TMX) has reached a milestone at its Lightning Gold Project, completing a critical four-hole diamond drilling programme that de-risks the project ahead of its maiden mineral resource estimate.
Located in the Murchison region of Western Australia, the programme delivered high-grade results that confirm both the geological model and the continuity of mineralisation across the Lightning and Monza structures.
Drill hole SBDD002 returned a high-grade intercept of 3.4m @ 4.96 g/t gold from 213.6m, including a standout 1-metre zone at 10.93 g/t gold, validating the presence of higher-grade gold at depth.
The technical success of the programme provides the final essential data—including oriented structural data and bulk density measurements—required for the upcoming July 2026 MRE.
By securing these inputs, Terrain has finalised a comprehensive 16,000-metre drilling database comprised of 97 RC holes and 4 diamond holes.
The dataset ensures that the upcoming resource definition is grounded in high-quality, professional-grade geological insights.
With the MRE on track for July, the company is now eyeing a clear pathway towards resource growth.
The mineralisation remains open both along strike and at depth, suggesting substantial exploration upside beyond the initial estimate.
The company plans to commence formal mining studies alongside its ongoing exploration efforts.
At the time of reporting, Terrain Minerals' share price was $0.0050.
