BOW, this taken from Richfeilds technical report, there are some Quantec images in this report also, but I dont know how to get them put here. Here is what they are saying about Quantec;
During 2010 Richfield contracted Quantec Geoscience Ltd of Toronto to conduct a 17.5 line
kilometer deep focus IP survey on five 3.5 km long north-south lines spaced 400 m apart.
Results of the survey have been reported and interpreted in terms of drill data. Excellent
correspondence is seen between chargeability and known mineralization and the IP data
helps guide the drilling.
Figure 10-1 is a view looking northwest across the IP survey area showing chargeability
variation across the project. Figure 10-2 is a plot of the chargeability data through the
centre of the mineralized zone. The high near-surface zone between 2500 and 3500N
coincides with the gold mineralization.
The reason the Chargeability is picking up the highest gold grades there, are because of the presence of silver.The silver is associated with the gold, or vice versa, it doesnt matter But it is interesting to see that the milligrads of chargeability used there is 50 mrd,s in their block model in comparrison to our 16 or 18 mrd,s. I notice that we use transmitter type GGD and they used type DDG. This must in some way account for the scale difference of the mrd,s.
So, they found out, that by making an association that the silver is with gold, and that the quantec picks up silver on the chargeability , they knew where to drill for the highest gold grades. Defined a resource more quickly and are now receiving an offer.
