AMN - GUINEA: Lola graphite drilling extended

After receiving strong graphite results from drilling at the Lola Graphite deposit in Guinea, SRG Graphite, which is 35.54%-owned by Sama Resources, has decided to extend the drill program. This decision will also take advantage of the cost-beneficial drill rig that SRG has on site.

Assay results have been reported for 162 new boreholes drilled since mineral resources were announced last June, bringing the total to 557 boreholes over 18,037 metres.

The third phase of the drill program is ongoing with 60 additional boreholes over 3,000 metres completed so far.

The additional drilling program includes 10 boreholes designed for testing graphitic carbon at depths within the non-weathered rock assemblage below the graphite-rich surface saprolite.

Highlights of the latest results:

- 55.5 metres at 8.92% graphitic carbon, including 48 metres at 10.07%;

- 38.05 metres at 8.67%, including 23.05 metres 13.12%;

- 49.10 metres at 8.62%, including 21.40 metres at 17.61%; and

- 14.85 metres at 11.38%, including 12.85 metres at 12.94%.

Current drill-hole results cover about 60% of the deposit’s surface footprint. To date, only the weathered portion of the deposit has been drilled, representing the first 30 metres from the surface on average.

The latest drill results should help further understand the reach and depth of the deposit and, provide additional basis for the mineral resource update to be included in the feasibility study expected for the first half of 2019.

Core logging and sampling were performed at the SRG’s facility in the town of Lola. Sample preparation was performed by Veritas Laboratory in Abidjan, Côte d’Ivoire while pulp samples were delivered to Activation Laboratories Ltd, Ancaster, Ontario, Canada.

The samples were treated through a multi-stage furnace process to remove organic carbon and carbonate carbon. The remaining graphitic carbon was measured as carbon dioxide in the infrared cell as gas flowed through the cell.

Carbon dioxide absorbs IR energy at a precise wavelength within the IR spectrum. All analyses were performed using Eltra instruments.

SRG also advises that EEM Sustainable Management, a Canadian-based independent environment consultancy company from Montreal with significant experience in Guinea, has been selected to revise and update the Lola project’s environmental and social impact assessment to ensure compliance with local and international standards.

Sama is a Canadian-based mineral exploration and development company with projects in West Africa.
