The image on the left is from a magnetic interpretation. The image on the right is slightly more detailed than the mapped geology available from the OGS. The magnetic interpretation suggests all structural directions that have been observed in this geophysical overview
The right image suggests that near the western boundary of the Fortune claims that there are two parallel ultramafic/mafic NNW-SSE trending bodies. From examination of the magnetic data, it is my opinion that there are a single ultramafic/mafic (southern) and a less magnetic (northern) feature that merge towards each other. This closeness of the bodies increases the magnetic signatures of both
Mineral Deposits
In the Beck-Ottaway area Fortune will be looking for Ni-Co-Cu-PGE and Cu-Zn deposits similar to
- Crawford Main Zone and Annex
- Crawford-Nesbitt-Aubin
- Nesbitt North
- Mahaffy-Aubin
- Kingsmill
Regional Overview
The magnetic highs within and around the Fortune claims are prime areas for Ni mineralization based on the magnetic signatures of other ultramafic bodies associated with mineralization – see the areas of Crawford, Nesbitt, Mahaffy-
Regional Scale magnetic highs and ultramafic trends which are associated with Ni mineralization.
Interestingly, apart from Crawford, the known areas of mineralization do not correlate with strong conductors, and most of the conductors correlate with graphitic material. Later EM surveys (MEGATEM GDS 1041B) show similar results to the much earlier 1987 survey
Gold Exploration in the area
All three drillholes (OT81-1, OT81-2, 32910) are equidistant from a regional NW-SE structure and lie within a low mag area and there are indications of weak NW-SE structures.
