Prior to the commencement of the 2020 RC drill program, prospecting, review of historical drill core and rock sampling were conducted across the property. A total of 38 rock samples were collected, with a focus on expanding the footprint of known mineralization and demonstrating the potential for gold-enriched copper mineralization across the property. A summary of all rock samples collected at Jean Maire during the 2020 exploration season is presented in below.
A high-resolution airborne magnetic survey was conducted by Peter E. Walcott & Associates Ltd. covering the majority of the property, including the known areas of drill defined copper mineralization at the A, B and C Zones. The survey was flown along 100 metre spaced lines and 1,000 metre spaced tie lines. The survey expanded upon the existing historical ground magnetic survey completed in 1973 and provides a much greater level of detail at the known areas of copper mineralization. The survey also highlighted additional target areas in the southern portion of the property where historical soil geochemical sampling identified copper-molybdenum in-soil anomalies.
All of the geophysical and geochemical data collected during 2020 will be incorporated into the existing dataset and will be used to develop targets for follow-up field programs and drill testing in 2021. PEMC has now met its first-year expenditure commitments and have a property wide exploration permit through 2021.
Rock samples collected from the A Zone (Applecot showing) returned up to 0.442 g/t gold with 1.3% copper and 15 g/t silver. At the newly identified Leap Target area, 800 metres to the south of the B Zone, rock sampling returned up to 8.79 g/t gold, 86.7 g/t silver and 1.74% copper. Approximately 400 metres south of the C Zone, additional gold mineralization was encountered when continuous chip sampling of a hand trench (Trench 1) yielded 4.0 g/t gold over 8 metres with the entire 20-metre length of the trench averaging 1.7 g/t gold. A second hand trench (Trench 2) was sampled approximately 250 east of Trench 1 where continuous chip sampling yielded 4 metres grading 1.37% copper, 0.08 g/t gold and 67.4 g/t silver. At this time, the trend and true width of mineralization at both hand trenches is unknown.
The Jean Marie property is characterized by a northwest trending magnetic signature that traverses the property from south-east to north-west. Results from the airborne magnetic survey highlight several areas where this dominant northwest trending magnetic signature is interrupted by east-west and north-east striking zones of magnetic disruption.
At the A Zone, where 2020 RC drilling was focused, the airborne magnetic survey shows an east-west zone of magnetic disruption that is interpreted to represent a structural discontinuity, favourable to host porphyry intrusions. In the southern portion of the property, a more heterogeneous magnetic signature is observed. Rock sampling in this area by PEMC during 2020 returned up to 0.218% copper and 176 ppm molybdenum.

Historically, the A and C zones did not see systematic analyses for gold. Entire hole composites from 1974 percussion holes were assayed for gold with a high detection limit and, as such, gold was not detected. The recent collected rock samples show that there is, in fact, a significant precious metal component associated with copper mineralization, at least in part, at the A and C zones.
