Buxton Resources (ASX:BUX) said heritage clearances were received for the Madman project in Western Australia; however, a modified access route delayed the start of drilling, according to a Tuesday Australian bourse filing.

Full clearances were granted for up to 30 drill pads, with associated camp sites, laydown areas, and access tracks. The heritage-cleared access route between the existing tracks and the planned drill area differs from the proposed alignment, requiring the firm to submit a new miscellaneous licence application, triggering talks to amend the native title agreement.

Drilling is now expected to begin no earlier than March 2026.

Geophysical surveys are planned for the December quarter and the March 2026 quarter across the firm's Western Australia projects to develop new targets for drill testing in 2026, along with ongoing generative work.

The firm's board is reviewing options to reaccelerate exploration activity at the Copper Wolf project in Arizona.
