Targets within the claim blocks are nickel-copper-cobalt-precious metal massive sulphides associated with the basal zone of differentiated gabbro sills in the Belleterre-Angliers Greenstone Belt (BAGB).
The 718-kilometre survey will be flown by Geotech utilising a helicopter-borne VTEM Max system.
All historical drill sites comprising nickel, gold and base metal targets will be evaluated by the VTEM survey, which has a proven record of locating discrete conductors to depths of 300-400 metres.
VTEM survey areas
600,000 tonnes of massive sulphide ore
Within the Lorraine project area, the VTEM survey will test the depth and strike of extensions at the Lorraine Mine which produced 600,000 tonnes of nickel-copper massive sulphide ore from 1965-68.
A 2005 drill program identified strong off-hole EM anomalies in the hanging wall of the deposit and around 200-metres of strike modelled conductor will be evaluated by the VTEM system.
Reinterpretation of 2015 aeromagnetic data has delineated extensive target gabbro bodies within the Lorraine claims, which will be also covered by the survey.
Near surface nickel-copper-cobalt
At the Alotta-Delphi-Zullo (ADZ) Project diamond drilling has outlined a substantial near-surface nickel-copper-cobalt-precious metal massive sulphide lens at the Alotta prospect.
The survey will target the strike and depth extensions to the host gabbro body, which is complexly folded within the ADZ claims.
Previously named TopTung Ltd, the company and its consultants Orix Geoscience and Core Geophysics, have been acquiring historical data for the Lorraine project tenements which comprise 90 claims covering about 46 square kilometres.
The data has provided further information on the Lorraine copper-nickel-PGE (platinum group elements) mine with over 30 mine plans detailing the historical mining between 1964 and 68 and will be digitised in order to provide control for targeting future drilling as deemed necessary.
Chase Mining’s executive chairman Leon Pretorius has recently demonstrated his faith in the company’s exploration strategy by acquiring 1 million shares on market following those last month of director Charles Thomas, who purchased more than 1.435 million ordinary shares with a total value of almost $25,000.
Compilation of historical geological, geophysical reports and drill data has resulted in the delineation of extensive prospective host gabbro sills within the Lorraine and ADZ claim blocks.
The helicopter-borne VTEM Max system is an ideal tool for locating conductors in resistive terrane as is present in the BAGB.
Geotech will mobilise to site in late February to early March with preliminary data being available by late March 2019.
