High Grade Copper and Zinc Mineralisation Confirmed
Comet Resources Ltd (ASX:CRL) has received high-grade results from mineralised samples taken during the field programme undertaken at the Barraba Copper Project located in the New England area of NSW.
Comet has now received complete assay results from samples taken from the historical high grade Murchison Copper Mine site and the Gulf Creek North prospects.
Managing Director, Matthew O’Kane, said the field programme included grid based geochemical soil sampling and rock chip sampling. Evidence of copper mineralisation was widespread around the Murchison Copper Mine.
Historical mine workings that were previously unknown to the company around the Gulf Creek North area and proximate to a number of chargeability anomalies identified by a prior induced polarisation (IP) survey were also assessed.
“These assay results, with high copper, zinc and cobalt, have confirmed that the historic Murchison Copper Mine at the Barraba Copper Project is another area of high priority exploration interest to us,” Mr O’Kane said.
“In addition to the known historical high-grade mineralisation at the Gulf Creek Mine, these results now provide us with multiple exploration targets at the project. We look forward to advancing physical exploration works on both prospects.”
The Murchison Copper Mine produced ore in the early 1900’s with historical records indicating the presence of underground workings to a depth of 16 metres, as well as a number of shallow pits. Copper and zinc mineralisation were the primary commodities of interest. Historical production records state copper was produced at an average grade of 3%, with historical assays up to 5.1%.
The initial field programme focused on delineating the tenor of the visible mineralisation as well as its extent. Accordingly, a number of mine dump and outcrop samples were taken for laboratory analysis. In addition, a number of grid-based soil samples were taken across the perceived strike of the mineralisation.
The programme entailed the analysis of rocks and soils by SGS laboratories (SGS) in conjunction with in-situ field analysis utilising a Niton personal XRF analyser (p-XRF). All soil sampling was based on a grid array, with samples taken every five metres on the two central lines and then every 10 metres on the outer two lines. All four survey lines were orientated approximately South-North.
