Monger Gold (ASX: MMG) has identified copper and zinc in rock chip samples from the Ben Nevis prospect within the Mt Monger South project in Western Australia.
Copper assays to a maximum of 1,086 parts per million and zinc assays to a maximum of 3,742ppm were returned from a total of 23 anomalous samples.
They extend the Ben Nevis surface anomaly to 150m in length with one anomalous sample located a further 180m to the west.
The anomaly is now over 230m strike within a broader prospective zone of 5km of continuous strike, with an increase in zinc found towards the west.
Monger said the previously underexplored area is now being interpreted as a potential zone of copper and zinc VMS (volcanogenic massive sulphide) style mineralisation.
The company is preparing to conduct a geochemical soil sampling program across all tenements next month and a second stage mapping program for July to build a structural geological model for the project.
All samples will utilise the Ultrafine+ fraction soil technique developed by CSIRO (Commonwealth Scientific and Industrial Research Organisation) in conjunction with Minerals Research Institute of WA and Geological Survey of WA.
The Mt Monger South tenement package sits within the Eastern Goldfields province of the Achaean Norseman-Wiluna greenstone belt.
The belt has been subdivided into a number of geological terranes separated by regional scale faults including the northwest-trending, east-northeast dipping Mt Monger fault.
Mt Monger South is in the Bulong Domain which consists of a discontinuous lower basalt then a lower intermediate to felsic volcanic sequence with associated volcanoclastic and conglomerate overlain by thick ultramafic to mafic successions.
The geological location is known as the Bulong Complex comprising Daisy Milano Komatiite, Wombola Dolerite and Mt Monger mafic sills and basalts.
Both sequences have been folded into a broad, north-south plunging feature known as Bulong Anticline and the project is situated in the southern hinge of this area.
