Dredge meaning gold2/19/2024 The high viscosity of bentonite helps to keep cuttings suspended in the fluid, ensuring efficient cuttings removal from the borehole. As the drilling progresses, the bentonite-based mud carries the drill cuttings (rock fragments, auriferous till and saprolite) back to the surface, which is then vacuumed into a tanker truck. Bentonite, commonly used in HDD, consists chiefly of crystalline clay minerals that help stabilize the borehole walls, preventing it from collapsing. The Company recently experimented with the technique by combining an HDD rig and a vacuum tanker truck to collect the mix of bentonite mud and drill cuttings. The technique is utilized to install or replace utility lines (such as pipelines, fibre optic cables, electrical conduits, etc.) without extensive excavation or disruption to existing infrastructure. Horizontal directional drilling (HDD) is commonly used in construction and civil engineering projects.

"Horizontal directional drilling has the potential to revolutionize placer gold exploration," said Patrick Levasseur, President, and CEO of Beauce Gold Fields. August 1, 2023) - Beauce Gold Fields (TSXV: BGF) (Champs D'Or en Beauce), ("BGF" or the "Company"): is pleased to announce it has tested the use of a modified horizontal directional drilling method to drill lengths of the auriferous till units of the paleoplacer channel on the Beauce Gold property located in St-Simon les Mine, Quebec.
