Dumas Contracting, a part of STRACON Group, has introduced the arrival of its latest manufacturing drill – a Sandvik DL331 – on the Las Chispas undertaking, owned by SilverCrest Metals, in Mexico.
The Sandvik DL331 arrived in time for the brand new 12 months, the corporate stated.
The Las Chispas operation is roughly 180 km northeast of Hermosillo, Sonora. A 2023 up to date technical report outlined an eight-year operation producing common annual manufacturing of 57,000 oz of gold and 5.5 Moz of silver in the course of the first seven full years. The up to date manufacturing plan reached barely above 1,200 t/d in 2026 and is essentially supported by long-hole stoping (77%).
The Sandvik DL331 is a top-hammer longhole drill engineered for work in underground mining drifts with cross sections of three x 3 m or bigger. This one-person-operated rig is able to drilling vertical and incline airplane rings and single or parallel lengthy holes. The drilling management system is fitted with feed-controlled percussion for optimum drilling efficiency and accuracy, Sandvik says.
The drill has a growth protection of seven m, together with a most gap size of as much as 23 m.
