Stellar’s 100% owned Mali subsidiary, Stellar Pacific Mali SARL, was awarded the Namanara Exploration Permit, a 52 Km2 in area located 130 km NW of Bamako in the Kankaba Circle of the Koulikoro district. This award of a full exploration permit followed an earlier short-term ‘look-see’ exploration authorization.
During the initial reconnaissance program over the Namarana Permit area, a total of 11 artisan mine sites were visited, mapped and sampled.

HISTORIC WORKS
In 2012, Newmont Mining in association with Stellar AfricaGold conducted a field reconnaissance and an airborne magnetic survey over an area of 132 km2, on the original Namarana permit area previously held by Stellar Pacific Mali SARL. The objective of the field reconnaissance and geophysical survey was the interpretation of the local geology. During this period, Newmont reported 4 significant grab samples results (48.4, 1.33, 2.16, and 1,14 g/T Au) taken in quartz veins observed in the northernmost artisan mine site. This site is at the contact of a small diorite intrusion clearly visible on the magnetic survey (see map below) and is a priority target for Stellar.
Magnetic Survey Result
Within the Namarana licence 52 km2, Stellar’s geologist, during a field visit in December 2020, reported 4 producing artisan gold mine sites where gold bearing quartz veins were exposed extending along geological and geophysical structures.
GOLD MINERALIZATION
The gold showings at the artisanal mine sites are closely associated to and located along a major NW-SE structure at the contact or near the contact of a Diorite intrusion.
Gold mineralisation was found principally in quartz veins filling extension structures of second generation, most probably created during the emplacement of the diorite intrusion creating a favorable environment to the circulation of mineralized fluids.
TRENCHING PROGRAM
The Namanara trenching program called for a total of eleven trenches. As reported on March 8, 2022, visually all trenches appeared to have intersected the targeted mineralized zones and the assay results from the trenches at Site 4 appear to corroborate that visual inspection.
Assay Results
Trench 4-1
- From meter 22 to 25: 0.36 g /t Au over 3 meters
Trench 4-2
- From meter 01 to 07: 0.5 g/t Au over 7 meters
- From meter 13 to 16: 0.22 g/t Au over 4 meters
- From meter 33 to 49: 2.90 g/t Au over 16 meters including 6.24 g/t Au over 3 meters
- From meter 50 to 56: 2.34 g/t Au over 6 meters including 3.47 g/t Au over 2 meters
Trench 4-3
- From meter 11 to 28: 0.80 g/t Au over 17 meters including intervals of 2.59 g/t Au over 1.0 meter, 3.42 g/t Au over 1.0 meter and 3.02 g/t Au over 1.0 meter
- From meter 59 to 68: 0.45 g/t Au over 9 meter including 2.41 g/t Au over 1.0 meter
Trench 4-4
- From meter 01 to 10: 4.40 g/t Au over 10.0 meters including 20.85 g/t Au* over 2.0 m
*Note: This interval included a sample that assayed at >100 g/t Au which was capped at 30 g/t Au. Due to ground conditions at the SouthWest end of the trench, T4-4 was stopped at meter 01 while still in mineralization and remain open.
Trench 4-5
- From metre 13 to 14: 9.2 5 g/t Au over 1.0 meter
- From meter 19 to 23: 11.48 g/t Au over 4.0 meters
With these results Stellar can confirm the discovery of an extensive high-grade gold structure on Stellar’s 100% owned property in Mali. (see figure below) Planning for a follow-on drill program is underway.
