Major Drilling says its Mexico division recently drilled its deepest NQ diameter hole at the Industrias Peñoles-owned Bismark mine in Chihuahua.

The drill hole, which reached just over 1,985 m, is a “true milestone for drilling operations in the region”, Major Drilling said.

Cory Crawford, Major Drilling Mexico Assistant Branch Manager, said: “These are not easy holes to complete. Being dry holes, we have to use special back-end dry hole valves made in house.”

Major Drilling established its first contract with Industrias Peñoles just 18 months ago and has already drilled nearly 50,000 m for the miner. Its core drilling contract at Bismark is to explore and support long-term mining, it said.
