IronRidge Resources Ltd, an African focused minerals exploration company, has reported additional high-grade drilling results from the second phase drilling programme at the Ebilassokro and Ehuasso targets, both within the Zaranou Gold Project area. The license borders with Ghana and is along strike from significant operating gold mines including Chirano (5 million oz), Bibiani (5.5 million oz) and Ahafo (17 million oz).
- New high-grade 4 m composite reverse circulation (RC) drilling results received for the final second phase drill holes completed over the Ehuasso target, including at the Ehuasso Main target, reported at a 0.1g/t cut-off and maximum 4 m of internal dilution.
- Mineralisation continuity now confirmed over a 1.7 km strike at the Ehuasso Main target, with mineralisation open to the south-west and at depth; follow-up phase 3 infill RC drilling now underway.
- Additional high-grade air-core (AC) results (from the previously reported 4 m composites on 30 July 2020) received for 1 m primary samples over the Ehuasso target, reported at a 0.1g/t cut-off and maxi-mum 4m of internal dilution.
- Further new AC drill intersections reported at the Ebilassokro exploration target in 4 m composite samples along the second reconnaissance drill traverse, reported at a 0.1g/t cut-off and maximum 4 m of internal dilution.
- Third phase 50 000 m RC and AC drilling programme now under-way with two drill rigs active on site and a third rig planned to arrive within four weeks.
Commenting on the company's latest progress, Vincent Mascolo, CEO of IronRidge, said: "As expected, Zaranou continues to deliver outstanding drilling results and the Board's confidence in a significant project grows on each drill hole and gold mineralised intersection.
"With only 12 km of 47 km of potential strike having been drill tested to date, we have already uncovered three exciting target zones - Ehuasso, Yakasse and Ebilassokro with additional targets M'Basso and Coffee Bean/Super Pit – complementing an additional untested 8 km strike of hard-rock artisanal workings to deliver a pipeline of further discoveries.
"Ehuasso is the most advanced target area with mineralisation continuity now defined in 160 m spaced AC drill traverses over 1.7 km strike and up to 70 m of apparent thickness, drilled to a maximum vertical depth of 100 m and remaining open along strike and at depth.
"Our early ounces strategy is to target weathered oxide mineralisation, with initial observations suggesting it continues to average depths of 50 m and up to 90 m, suggesting simple mining and processing at low operational and capital costs.
"Our longer-term strategy is to extend a resource at depth within fresh material where initial RC results have intersected high-grade mineralisation.
"The third phase 50 000 m combined AC and RC programme is now well underway with two drill rigs active on site and a third rig planned to arrive shortly."
High-grade gold intersections
All 4 m composite drill assay results have now been received for the remaining RC and AC drill holes completed at the Ehuasso and Ebilassokro targets within the Zaranou license.
All sampling was completed at the drill site and consisted of initial 4 m composites submitted for analysis, of which all composites greater than 0.1 g/t gold are re-submitted for analysis at 1 m intervals from retained primary samples at the project site. ALS laboratory completed sample preparation in Côte d'Ivoire and sample analysis in Burkina Fa-so, with results passing internal and laboratory QA/QC protocols, providing confidence in reported results. All AC and RC drilling to date has been completed at -55 to -60° dip.
The new 4 m composite results in remaining RC holes over the Ehuasso target provide further significant intersections within the Ehuasso Main target including 40 m at 1.29 g/t from 80 m (including 4 m at 9.9g/t) in hole ZARC0019 and new high-grade intersections at the Ehuasso target, including 16 m at 10 g/t from 44 m (including 4 m at 25.1 g/t) in hole ZARC0022. The broad and high-grade results provide further confidence in strike and depth continuity at the Ehuasso Main target and also define new high-grade targets.
The newly reported 4 m composite RC intervals provide confidence in continuity of mineralisation within the Ehuasso Main target zone and confirm mineralisation over 1.7 km of strike and up to 70 m apparent width, which remains open along strike to the south-west and at depth.
Primary 1 m samples from previously reported 4 m composites over the Ehuasso target have returned broad and high-grade gold inter-sections within the Ehuasso Main target including highlights of 6 m at 9.08 g/t from 53 m in hole ZAAC0436, 2 m at 20.43 g/t from 58 m in hole ZAAC0432 and 24 m at 1.14 g/t from 12 m in hole ZAAC0427.
The newly reported 1 m primary sample results reaffirm previously reported 4 m composite results within the Ehuasso target and provide greater resolution to 1 m sample intervals within mineralised intervals, whilst managing assay costs.
The new 4 m composite results in remaining reconnaissance AC holes over the Ebilassokro target provide further encouraging results including 4 m at 6.13 g/t from 52 m in hole ZAAC0460 and 24 m at 0.32 g/t from 16 m in hole ZAAC054.
The newly reported results at Ebilassokro complement previously reported results (with highlights of 5 m at 270.5 g/t; and justify further step out exploration AC drill traverses along the target.
The third phase 50 000 m combined AC and RC drilling pro-gramme is progressing well with two drill rigs currently on site and drilling at the Ehuasso Main and Ebilassokro targets, with a third rig due to arrive on site within the coming weeks.
Drilling is planned to continue over the Ehuasso, Ebilassokro, Coffee Bean, M'Basso and Yakassé targets up to the end of 4Q20 with re-sults reported as they become available.
