Drilling continues to define and extend mineralisation at Eleonore

Algold Resources Ltd. has announced further preliminary assay results from its Phase IV 25 000 m drilling campaign carried out on the corporation’s Tijirit property in Mauritania.
- Hole T18RC059 (Eleonore South) – 37.35 g/t Au over 2 m, including 60.7 g/t Au over 1 m on section E8380, within the open pit limits defined in the preliminary economic assessment, and 30 m north of hole T16RD041, which intersected 36.09 g/t Au over 1 m, including 65.0 g/t Au over 0.5 m.
- Hole T18RD054 (Eleonore South) – 11.23 g/t Au over 2.7 m, 7.65 g/t Au over 3.3 m and 6.04 g/t Au over 4 m on section E8430, located 40 m below hole T17RC112, which intersected 1.21 g/t Au over 8 m. Infill drilling on the same section, 58 m above hole T18RD054, identified a visible gold bearing quartz-carbonate shear vein 59 meters depth in hole T18RD055 – 21.9 g/t Au over 0.5 m.
- Hole T18RC089 (Eleonore South) – 1.75 g/t Au over 10 m on section E7780, located 16 m above hole T16RC077, which intersected 0.74 g/t Au over 4 m.
- Hole T18RC090 (Eleonore South) – 7.97 g/t Au over 3 m on section E7825, located 25 m south of hole T17RC122, which intersected 8.16 g/t Au over 5 m.
These drilling results reported, from the Eleonore South zone, continue to validate the spatial continuity of the mineralisation identified to date and, importantly, demonstrate that high grades are recurrent along strike and dip.
The Eleonore South mineralisation extends over 1.2 kim from north to south and is the southern-most zone defined thus far on the 3.4 km long Eleonore structure. Several discrete shear zones that may control the high-grade gold mineralisation remain largely untested at depth. The Eleonore South zone geology is similar to other zones, with the mineralisation hosted within mafic volcanics and quartz-rich porphyry; it is separated from Eleonore Central by a fault.
Detailed observations from core drilling suggest dominant steep-dipping mineralized zones related to regional schistosity and folds. The presence of a possible shallow east-dipping late mineralised shear is being currently tested. Rheological contrasts and zones of weakness are important factors in the controlling of shear propagation and mineralisation emplacement.
The Phase IV 25 000 m programme was initiated on 7 May 2018 with an objective to complete an initial 15 000 m of drilling by mid-July in order to upgrade inferred resources to the indicated and measured category using a 40 x 40 m grid. To date, Algold has completed 12 900 m of reverse-circulation (RC) and 6930 m of diamond drilling.
From the initial 15 000 m of drilling, the company is in receipt of results from approximately 80% of RC and 37% of core samples that were sent to the laboratory for analysis.
