IronRidge Resources' high-grade rock-chip assay results with grades of up to 39 g/t gold have been received from new artisanal workings within the Dorothe prospect, as well as anomalous 1 g/t gold from outcrops to the south of the Dorothe prospect.
Central Africa - Additional anomalous copper grades of up to 1.05% have been received from rock-chip samples over a pXRF soil anomaly to the south-west of the Dorothe prospect.
Two new licenses have been granted to the wholly owned Tekton Minerals with extensive artisanal workings and visible gold mapped.
"High-grade rock chip results up to 39.1 g/t gold from new workings occurring within the Dorothe prospect continue to reinforce Dorothe as a high-priority target; we eagerly await assay results for the 9,270 m of trenching completed," comments IronRidge Resources CEO Vincent Mascolo.
"New targets to the west and south of the Dorothe prospect have delivered encouraging results, ranging from 1.05% copper and up to 1.1 g/t gold in rock chips, further highlighting the exploration potential within the portfolio.
"Securing the Kalaka license has been a key focus; we are very pleased to consolidate the IronRidge Resources' position along this highly prospective and under-explored gold corridor.
"Field programmes for the 2017-2018 season are approaching completion prior to the commencement of the wet season, and with the reporting of initial assay results, we are anticipating regular news-flow as trenching and soil sampling results are received," he continues.
High-grade assay results
Assay results have been received for the initial mapping and rock-chip sampling programmes completed within the Dorothe license, prior to the commencement of trenching and concurrent with regional soil sampling programmes.
High-grade results of up to 39.1 g/t gold, 789 g/t Ag, >20% Pb and 0.48% Cu were returned from rock-chip samples collected within new artisanal workings at the Dorothe prospect, as first announced on 23 November 2017.
In addition to the vein material reported, rock-chip samples of the host rock with moderate to intense alteration, indicating mineralised fluid flow outside the vein, reported up to 1.27 g/t Au, 8.1 g/t Ag, 1840 ppm Pb, 274 ppm Cu.
Approximately 1.5 km south of the Dorothe prospect, rock-chip samples over the 'Camp One Vein' prospect returned anomalous gold results including 1.1 g/t Au with 12 g/t Ag and 1 g/t Au with 6 g/t Ag over a 1 km strike and representing potential southern extensions of the Dorothe prospect.
In addition to the high-grade gold results at Dorothe, the company has received encouraging copper assay results including grades of 1.05% copper from two reconnaissance rock-chip samples collected over pXRF identified copper in soil anomaly found during routine regional soil sampling.
Although at an early stage, the results highlight the potential for a possible bulk tonnage copper target where the pXRF soil anomalism is coincident with a biotite gneiss intrusive body and highlights the exploration potential for additional minerals and metals within the Chad portfolio.
In line with IronRidge's strategy to secure, and in a timely and proficient manner, explore highly prospective large scale scale projects, IronRidge Resources has successfully secured the Kalaka license whilst concurrently transferring the Nabagay reconnaissance permit to an exploration license; thus consolidating the company's position along this highly prospective gold corridor.
The newly granted licenses have been ratified into IronRidge Resources' exploration and mining convention, whilst the Ade license has been relinquished in favour of the Kalaka license consolidation.
The company's exploration portfolio now covers a combined surface area of 900 km2 along highly prospective structures and lithological contacts with extensive artisanal workings.
Recent mapping and aerial drone surveys have highlighted two extensive artisanal mining centres, now largely abandoned at Kalaka and Guerere; approximately 15 km and 6 km north of the Dorothe prospect respectively .
The Guerere workings, first announced on 12 June 2017, extend into the southern tip of the newly granted Kalaka license and was an important observation in the consolidation of the area between the Dorothe and Nabagay licenses.
All largely abandoned artisanal mining centres occur within favourable structural settings within large scale fold closures in the interpreted hanging-wall block of a major north-south trending fault structure.
At Kalaka, artisanal workings occur over a large 1 km x 1 km area, indicating the potential large scale of a mineralised system below.
