AMN - MAURITANIA: High-grade gold results at Tijirit

Algold Resources has received high-grade gold results from drilling at the Tijirit project in Mauritania. Results from drilling, including 26.73 g/t over 1.4 metres, further substantiate Algold’s confidence in the project.

Data and results from reverse circulation (RC) and diamond core drilling in July and August continue to confirm the high-grade nature of the shear-hosted mineralisation.

New drilling was carried out on the priority targets of Salma Vein System (SVS), Eleonore and Sophie while infill drilling was undertaken at Eleonore North, Central and South.

Apart from the 26.73-metre intersection at Eleonore North, other results include:

- 4.35 g/t over 10.07 metres at Eleonore Central, including 8.25 g/t over 4.3 metres;

- 8.23 g/t over 2.35 metres at Salma, 36 metres below the surface, some 150 metres along strike; and

- 1.22 g/t over 10 metres at Sophie II, 77 metres below surface, extending the known block of mineralisation a further 100 metres.

Results are pending for around 2060 samples from work carried out as part of the 25,000-metre phase IV drilling program. The corporation expects to receive the remaining analysis by the end of November.

At Eleonore, drilling continues to confirm the spatial continuity within the three zones tested - North, Central and South. Generally, drill spacing was at less than 40-metre centres, to allow conversion of current inferred resources to indicated.

The interpreted regional structures associated with the Eleonore mineralisation extend the entire length of Algold’s 300 sqkm mining licence and provide further targets for future exploration.

At SVS, results from Salma confirm the presence of a narrow, but high-grade, quartz vein hosted within a locally sheared granitoid and dipping shallowly to the west. Gold is visible in the core and variable results associated with the 50-gram fire assay analysis suggest that the gold distribution is highly erratic and nuggety.

Drilling confirms that 1250 metres of the northerly portion of Salma is consistently mineralised and remains open in all directions.

At Eleonore East, mineralisation is also associated with shearing in both the granitoids as well as the volcano-sedimentary rock package. Mineralogy is similar to Eleonore, but with the addition of arsenopyrite in the mineralised system.

At Sophie, a new zone, identified by trenching in 2017, is 900 metres south of the currently defined Sophie II mineralisation, where results include 1.43 g/t over 26 metres, and 800 meters from the Sophie III mineralisation, where results include 1.3 g/t over 10 metres.

Mineralisation is associated with a sub-vertically dipping banded iron formation (BIF). In trenching, the exposed BIF unit was mapped between six to 12 metres true width, with individual grades of up to 2.2 g/t.

This compares well with the BIF intersected in drilling, where mineralisation was intersected 90 metres down dip. Currently, the structure has been identified over 200 meters and remains open to the north and at depth.

The area remains highly prospective for the discovery of further gold mineralisation with multiple soil anomalies and BIF units identified that have yet to be tested, both on this and parallel structures.

Algold has also discovered a new zone of outcropping high-grade gold mineralisation about 4.5km south of Eleonore, along the same trend, where rock-chip sampling returned results up to 96.5 g/t.
