Gold-copper explorer Kalamazoo, which recently announced plans to ramp up gold exploration in the Pilbara, has released updated estimates from its Mixy gold deposit, part of its flagship Snake Well project.
The mineral resource estimate now stands at an average total of 65,000 ounces of gold from 470,000 tonnes (4.3 grams per tonne at a 0.5 grams per tonne cut-off grade), representing an 85 per cent increase in grade and 13 per cent increase in tonnage over previous estimates from May and June.
Snake Well has three lodes, an upgraded from the single lode reported last month; this is the result of splitting the previous lode into three zones, a main zone, a footwall and a hangingwall.
The gold lode on the main zone shows translucent quartz veins among mafic rock; it is up to 400 metres in strike length, up from the previous estimate of 50–150 metres. The footwall and hangingwall show gold grades of up to 2 grams per tonne, resulting in an overall boost for the newly classified main zone.
The estimate was carried out by Ravensgate in accordance with JORC 2012 guidelines. Peter Benjamin, resources managing director of Kalamazoo, said that the gold grade distribution at the project is now reasonably defined.
“If this trend is representative of the entire deposit then it is reasonable to expect that there is a high confidence in the remaining resource,” he said.
“The trial pit development and production demonstrated that the geological interpretation used in the resource is robust.”
