Amex Exploration Inc. (“Amex or the Company”) (TSXV:AMX)(FRA:MX0)(OTCQX:AMXEF) is very pleased to report the head grade from 3 metallurgy holes which were specifically drilled into 3 different Metal Factor isocontour areas of the High Grade Gold Zone of the Eastern Gold Zone (EGZ) at Perron. Please see Figure 1 for hole locations and Figure 2 for core photos. Results include:
- Hole PEM-20-001intersected 11.80 meters of 27.70 g/t Au for a metal factor (MF) of 326.86 gram metres of gold. This metallurgical test hole is located approximately 6 meters East of the previously drilled hole PE-17-03 that returned a MF of 59.09 gram metres of gold.
- Hole PEM-20-002 intersected 16.60 meters of 12.70 g/t Au for a MF of 210.82 gram metres of gold. This drill hole is located within the >100 gram meter gold isocontour which validates the high grade continuity of the system.
- Hole PEM-20-003 returned 10.60 m of 5.65 g/t Au for a MF of 59.89. This hole is located inside an area previously identified with a MF isocontour of 10 to 50 gram meters of gold.
These metallurgy holes were drilled using large diameter PQ size drill holes to provide enough material for proper and representative testing. The samples are now being processed and tested for recovery rates which the Company anticipates will be quite high given the ore mineral assemblage of free visible gold, with a low percentage of sulfides including dominantly sphalerite and lesser pyrite.
The metallurgical drill holes were drilled in areas of the upper near-surface portion of the High Grade Zone (HGZ) that were anticipated to provide representative high, medium, and low grade samples, as shown on Figure 1. The bulk samples included the hanging wall and footwall veins, as well as the weakly mineralized interior mafic dyke rock, with the objective of testing representative mining widths across the entirety of the HGZ. The results, both on a visual level and with the head grade reported below, exceeded expectations. Of interest is the significant increase of visible gold grains and associated high grade mineralization in holes PEM-20-001 and PEM-20-003, which indicates that larger diameter drilling may be related to an increase in grade.
Jacques Trottier, PhD Executive Chairman of Amex said, “There are several important things that we have illustrated with the drilling of these larger diameter PQ holes. First, when reviewing the longitudinal, the larger diameter drilling demonstrates mineralization is richer than previous drill holes indicated, given that 2 of the 3 holes returned a higher metal factor than was previously indicated for their location. This is common with very high grade Archean gold mines, where the mined head feed ore sent to the mill is often richer than indicated by core drilling intersects that were used in resource calculations.”
Trottier continued, “Second, we are seeing tremendous vertical continuity and homogeneity of the very high-grade zone with coarse gold grains. These large diameter holes are very useful in validating true high grade mineralization values. Finally, we believe the recovery rate is going to be very significant by simple gravity separation process given the amount of free gold in the samples. I am keen to see the recovery rates following the next phases of the ongoing metallurgy test program.”
Three samples of full PQ core in drill core boxes were delivered to SGS Canada Inc.’s facility in Quebec City on July 9th, 2020. Each sample was stage crushed with a combination of jaw, cone and rolls crusher to passing ½”, and ¼ of the sample was rotary split and further crushed to 100% passing 6 mesh. The sample was homogenized, and a 10 kg sub-sample was rotary split for Bond ball mill work index testing (BWI) and the remainder was crushed to 100% passing 10 mesh. The sample was homogenized, and rotary split into 10 kg test charges and a 1 kg head assay charge.
The 1 kg charges from each sample were submitted for gold analysis using the screened metallics protocol. The method involves several stages of pulverizing and screening the pulverized sample at 150 mesh (106 µm) until approximately 20-30 g of material remains in the screen oversize. The screen oversize and duplicate samples of the final combined screen undersize are submitted for chemical analysis and the head assay of the sample calculated from the relative distribution of the screened fractions. The results shown in Table 1 below indicate gold grades ranging from 5.65 g/t Au to 27.7 g/t Au, and high gravity recoverable gold for all three samples.

Amex Exploration Inc. is a junior mining exploration company, the primary objective of which is to acquire, explore, and develop viable gold projects in the mining-friendly jurisdiction of Quebec. Amex is focused on its 100% owned Perron gold project located 110 kilometers north of Rouyn Noranda, Quebec, consisting of 116 contiguous claims covering 4,518 hectares. A number of significant gold discoveries have been made at Perron, including the Eastern Gold Zone, the Gratien Gold Zone, the Grey Cat Zone, and the Central Polymetallic Zone. High-grade gold has been identified in each of the zones. A significant portion of the project remains underexplored. In addition to the Perron project, the company holds a portfolio of three other properties focused on gold and base metals in the Abitibi region of Quebec and else where in the province.
