Original sentence: 80% of past drilling in the area was completed to depths of less than 50 metres and was generally only focused on known deposits within a limited geological assessment.Historically, the Davyhurst field has produced some 1.15 million ounces of gold since 1897.In early 2006, Monarch further expanded its position at Davyhurst through a merger with Siberia Mining Corporation.Monarch acquired the Davyhurst Project in November 2005, comprising an 808,000 ounce resource base, 841km2 tenement package, a 1.2 million tonne per year gold processing facility, administration offices, an accommodation village and associated infrastructure.Monarch is now the largest Australian-controlled ground holder in the Kalgoorlie region.The Davyhurst Gold Project is located approximately 120km north-west of Kalgoorlie, and is a core component of Monarch’s consolidated gold resource base in the Northeastern Goldfields of Western Australia.The Project which is located within the prolific Davyhurst-Mt Ida greenstone belt, has significant exploration potential.This belt hosts two major geological structures, the Zuleika Shear and the Mt Ida Fault, which have a close association with gold mineralisation in the region and reportedly control a 10 million ounce gold endowment.This merger resulted in the strategic consolidation of the nearby Siberia and Ida Gold Camp deposits into Monarch’s existing holding, establishing a consolidated project with a combined resource base of 2 million ounces of gold within a 2,000 km² tenement package including a centrally located gold treatment facility and production infrastructure
