The Yilgarn Craton forms the bulk of Western Australia and is home to 30% of the world\u2019s gold deposits. Within in this region, the Laverton district is one of the most important gold producing regions. Underground miners of these \u201cnuggety\u201d gold deposits are under significant pressure to reduce their all in sustaining costs (AISC) and improve their return. Combine each mine\u2019s sharp focus on costs with an extremely competitive diamond drilling market, and the result is the constant search for higher productivity in underground diamond drilling.<\/p>\n<\/div><\/div><\/div><\/div>\n\t\t\n\t\t\n\t<\/section>

Using patented technology, the new Longyear bits have diamonds that are chemically bonded to the matrix creating a more versatile, faster penetrating, and a longer-lived bit. The new Longyear bits retain the smooth drilling characteristics drillers prefer, resulting in more core in the box on every shift for every crew. Available in 16mm more open, express geometry for even higher cutting speeds as well as 16mm Stage and 25mm Stage 3 configurations.<\/p>\n<\/div>

On the surface, the Laverton district is a flat, hot, dry environment with scattered acacia trees only interrupted by dry, salt lake beds, and gypsum sand dunes. The high concentration of salt results in a very saline aquifer. While the high salinity is hard on equipment it does not factor heavily into bit selection and drilling performance.<\/p>\n

Underground, the formation is a mesothermal, meaning deep extending, gold deposit typical in Western Australia, composed of greenstone, a rock type common to gold deposits globally, basalts, magnetite shales and banded iron formations (BIF). \n<\/div><\/div>
