FMR Resources (ASX:FMR) has identified further targets via the compilation of additional historical geophysical and geochemical data at Dorchester North, within the 100% owned Fairfield Copper Project in New Brunswick, Canada.
“It is very encouraging to identify new targets close to the historical Dorchester Copper Mine as we prepare for the upcoming airborne VLF survey, which aims to detect conductors associated with sulphide minerals,” Non-Executive Director, Bill Oliver, said.
“These IP targets have never been tested by drilling and are likely to be a high priority when we look to start drilling at Fairfield later in the year.
“We look forward to the survey refining the known targets we have identified to date at Dorchester North and other prospects at Fairfield as well as hopefully identifying new targets across the Project. Canadian copper projects are in the news currently with the success of Firefly Metals and Firetail Resources on the ASX and FMR is pleased to be part of the increase in exploration activity in the region.”
New Targets Identified at Dorchester North
The data from an IP dipole survey completed in the 1970’s in the Dorchester area has been reprocessed and used to generate new targets. There are some key characteristics which can be observed in the IP response above the known copper mineralisation at the historical Dorchester Copper Mine (located
outside FMR’s tenure).
In the search for similar geophysical signatures at Dorchester North, three areas of interest have been identified. These three targets are supported by geochemical data and other information in the source reports.
Target 1 “Woodhurst North” is located 2 km north-northwest of the historical Dorchester Mine and is characterised by a large conductive anomaly 1.5km long with variable width and centred on the prospective horizon and a smaller chargeability offset to the east into the Boss Point formation.
The target is supported by elevated copper-in-soils above 10 ppm Cu with individual results up to 184 ppm Cu as well as recorded copper occurrences along strike 1km to the west with assays up to 0.4 g/t Cu and 6 g/t Ag1. Woodhurst North has never
been drill tested.
Target 2 “Antenna” is located 1.5 km northeast of the historical Dorchester Mine and is characterised by a 900m long conductive anomaly that trends southeast from the prospective horizon sub- parallel to an extensive chargeability offset to the east into the Boss Point formation. The target is supported by elevated copper-in-soils above 20 ppm Cu and individual assays up to 720 ppm Cu as well as a mapped copper occurrence. The Antenna target has never been drill tested.
Target 3 “Sparky” is located 2 km north-northeast of Dorchester Mine and is characterised by another 1km long conductive anomaly that tends northwest along the prospective horizon sub- parallel to an extensive chargeability offset to the east into the Boss Point formation.
Very little work has been done across the target and no soil sampling has been carried out to support the anomaly. The Sparky target has never been drill tested.
In the 1970’s Gulf Minerals held the tenure around the Dorchester Copper Mine. Mineralisation at the Dorchester Copper Mine is recorded to occur at the unconformity contact between the Boss Point formation “grey beds” and the Hopewell Cape formation “red beds”, the “prospective horizon” which forms the primary target for FMR’s exploration. This deposit style is categorised as a Sediment-Hosted Copper Sulphide Deposit.
In the period between 1976 and 1977, Gulf Minerals conducted extensive work programs starting from the mine itself then progressing northward along strike to track the prospective horizon into the area which is currently held by FMR.
