Question from the Donner Minerals thread:
Kent,

The surface survey is going to be used to "resolve" this same off-hole anomaly at over
500m depth. What depth to source did the modelling of the magnetic data give? How
are the two/three related? You can respond on the GYR thread if you like.


The off-hole anomaly is on the Okak Bay property, and was indicated by a borehole UTEM survey on Hole OK-M1 in November, 1997. Unfortunately we could only use a BH UTEM 3 survey (the BH UTEM 4 had some technical problems) so we will reshoot the hole with a BH UTEM 4 this year. La Montagne geophysics did our work last year, and will be doing it again this year. 80 kilometres of grid lines have already been laid down by our skidoo and snowshoe equiped ground crew.

The 1998 exploration program for the Okak Bay project will almost entirely focus on precise definition of a deep seated target(s) which is inferred to date from drill hole OK-M1 completed last November. Laboratory research of the drill core carried out at Memorial University in St. John's, NFLD confirmed the presence of the principal mineral ssemblage contributing to the rich nickel sulphide ores at Voisey's Bay and the nickel rich sulphide mineralization discovered at Voisey's Bay South. Other similarities observed during the research at Memorial include the gangue (waste) mineral, magnetite, and the alteration mineral, biotite which are both diagnostic of the Voisey's Bay ore zones. The identification of nickel rich pentladite in drill core is significant and validates the accumulation of nickel rich mineralization on the Okak Bay property.
The first phase of the 1998 work program will commence with the large loop (2km x 2km) surface electromagnetic survery capable of detecting and precisely fixing mineralized zones down to a depth of approximately 650 metres (2130 feet) which is 161 metres (528 feet) below the top of the mineralized zone intersected in Hole OK-M1. In concert with the surface survey a borehole BH UTEM electromagnetic survey will also be carried out on OK-M1. The down hole survey will improve greatly the precise fixing of the dimensions and location of the off-hole anomaly.
Phoenix Geophysics of Toronto, Ontario is completing an improved and more detailed analysis of the magnetotellurics data obtained during the survey completed last summer. This research is also utilizing a magnetic "inversion" technique to upgrade the interpretive results. This report will be completed within the next few days and will be integrated with the UTEM results to provide a definitive picture of the subsurface mineral potential.
