The latest update is out from Heartfield Mining Corp. ( (TSE:MERC) ).
Mercado Minerals has secured an exploration drill permit for its Copalito Project in Sinaloa, Mexico, clearing the way for a 3,000‑metre inaugural diamond drill program expected to begin in the first quarter. The permit allows use of both existing and new drill pads to test extensions of known veins, conduct infill and deeper drilling, and evaluate newly identified targets, building on 81 historical drill holes and prior prospecting.
The company has completed a drone-based LiDAR survey and is finalizing data interpretation, while a high‑resolution UAV magnetic survey is nearing completion to refine subsurface targeting. Concurrently, its geological team is advancing fieldwork through re-logging and re-sampling historic core, mapping previously unexplored areas, and running soil sampling campaigns to characterize mineralized veins and generate new drill targets, collectively positioning Copalito for a more robust and data-driven exploration phase.
