Nordica NR Aug 3The following are a few comments on RT Mineral's latest news release of Aug 3, regarding the rock sampling of the outcrop in the Sylvia Lake area. This is very encouraging news, to know that elevated values of Ni, Cu, Cr and PGE were encountered in Sylvia Creek. It bodes well to know that the Nordica Intrusion at least extends this far south, and west from the original Windward discovery area to the east. The outcrop was known back in 2022, when Garry Windsor spotted it, but I'm not aware of any samples taken and their results. In his report (20000020498/20000020498), he states;
"I located what appears to be an extension of intrusion 2 kilometres to the west. At the new location the bedrock is highly serpentinized and contains traces of PGE mineralization, copper and nickel with high levels of chrome in spots (10%). Although the intrusion is difficult to trace due to the overburden, this second location of similar outcrop is an ideal spot for a diamond drill setup. Throughout the entire area these are the only two outcrops that prove the continuity of the layered intrusion".
Some of the questions that came to mind about the RTM samples were:
a) what were the host rocks of the RTM samples?
b) were they able to see the full width of the chromite band (layer)?
c) were the rock types serpentinized?
d) were the chromite samples taken from random ultramafic rock samples, or were they taken from a separate unique chromite band?
e) in reference to the magnetics mentioned in the news release, was this from a hand held magnetic susceptibility meter?
That said, I overlaid Figure1 (location of RTM's Sylvia Lake samples) from the Aug 3 news release, over the Shaded Image of the 2nd Vertical Derivative of the Magnetic Total Field (Map 82053).
Sylvia Lake Outcrop UTM Easting 527050
Northing 5345350
Then referring to Map 82053, I noted that the Sylvia Lake samples are located in a Magnetic Low, not a magnetic high, using the above UTM co-ordinates. The magnetic high (Trend A) is in fact located about 250m east of the RTM sample location and 100m east of the bush road. The NW/SE magnetic trend that is located within the eastern shoreline of Sylvia Lake, is about 200m southwest, away from the RTM samples.
HTX Minerals, in 2013, took their sample about 500m east-southeast of RTM's sample location, but it was taken on the magnetic high (Trend A), where they got interesting Ni, Cu, Cr and PGE results.
Correct me if I'm wrong, that the RTM samples were taken from a magnetic low, and not from a magnetic high, where I think the best results will come from.
As I've previously said, this is very encouraging news. However, much more has to be done. It seems to me that the entire southern contact (base of the Nordica Intrusion) should be the area of interest, along its entire length, looking for embayments or troughs in the footwall, where mineralized pods would form, just like what happened at either Voisey's Bay or in the Sudbury Basin.
One final note. The airborne EM conductor (Maps 82218 and 82059), west of the Windward discovery, and the only conductor within the entire Nordica Intrusion, should be given a high priority for a prospecting program.
