Mountain View Project
The historic Mountain View workings and the small scale 1990’s open pit (within the granted 5 Ha Mining Licence ML5559) lie some 35 km southwest of Corryong within the company’s namesake historic Dart Goldfield. The Mountain View open pit was established on the main Mountain View lode, one of many small historic mines that extend along the Dart Goldfield for over 5 km. The drill definition of a shallow high grade zone below the existing open pit presented Dart Mining with an ideal opportunity to transition to production at a small scale following a full evaluation of the projects economic viability.
A bulk sampling program was designed and completed to provide gold recovery details and indicative processing operating costs associated with consumables. The bulk sample was excavated from a shallow trench in the base of the existing open pit. The sampling targeted what is interpreted to represent the upper portion of a high grade shoot (silica / sulphide lens) developed within the envelope of the Main Lens structure, exploited by the existing open pit (mined in 1992 by a private company). Drilling carried out by Dart Mining had identified high grade gold intersections of up to 2m @ 59.3 g/t Au (MVD20) only some 3m below the current pit floor. The shallow bulk sample excavation uncovered a silica / sulphide rich lens less than one metre below the pit floor (Photograph 1 & 2), enclosed within an envelope of lower grade material, consistent with the geological model.
Drilling to date consists of two phases of Rotary Air Blast (RAB) drilling and one phase of reverse circulation (RC). Drilling below the historic main lens outlined a very high grade gold lode, incorporating over 50 gram-metres in three drill holes within a larger lenticular lode channel up to 6 metres in true width. Highlights included drill intersections of 6m @ 7.8 g/t Au (including 2m @ 19.3 g/t Au) – DMVRC04 and 4m @ 8.72 g/t Au (including 1m @ 18.75 g/t Au) – DMVRC05 (refer DTM ASX Report for the Quarter ended 30 September 2009 – 20 October 2009). This style of target fits well within the developing small scale (5,000oz – 50,000oz) gold strategy adopted by the company
