McQuibbanBack in 1995, Noranda Mining and Exploration carried out ground magnetic and HLEM surveys at a 200m line spacing, that covered RTM's McQuibban property (OGS Assessment File 42H10SE0001). This resulted in a long linear east west magnetic trend, produced 2 long east west conductors and one short conductor. The most southerly long conductor correlates closely with the north contact of the long magnetic trend, while the long northerly conductor is located about 350m-400m north of the magnetic trend.
The magnetic feature is believed to be caused by an oxide iron formation. It exhibits a susceptibility that is mostly consistent along the trend. However, there is one section where the magnetic intensity weakens over 1 km long. This is an area where there may have been magnetite destruction, caused perhaps by intense alteration. These kinds of scenarios can often be areas that attract gold and therefore, this area may be a potential target for gold.
There is a very sharp circular magnetic low that is located in the eastern region of the RTM McQuibban property, that has a magnetic low of about minus 800 gammas. It has a dimension of about 300m by 400m. Could this negative magnetic anomaly be a result of reverse polarization, or could it be a quartz feldspar porphyry intrusive, or a syenite intrusive, or could kimberlite be the source?
Between the above 'intrusive' and the oxide iron formation to the south, there is a short NE/SW trending magnetic low, that looks like a splay fault coming off the main positive magnetic trend. It may also be related to similar rock types as mentioned above.
Noranda Mining never did any diamond drilling on this property.
