A 30 t excavator was mobilised to site on 14 November and is expected to arrive on site this week with trenching expected to continue until Q1, 2018.
The aim of the Dorothe trenching programme is to define grade, width and strike continuity of surface mineralised zones intersected to date within the Dorothe project over a 1.8 km x 1 km area at 200 m trench spacing. Results from the trenching programmes will assist in designing a maiden drill programme.
Commenting on the company's latest progress, Vincent Mascolo, CEO of IronRidge, says, "Regional soils and mapping programmes over the portfolio, as well as detailed structural mapping at Dorothe and Am Ouchar, will help us to prioritise prospects as we move towards maiden drill programmes."
"Dorothe represents an exciting, high-grade gold target with significant scale potential. It is one of multiple gold targets within the company's Chad portfolio."
Field teams have mobilised to site to commence regional soils and mapping programmes across the Dorothe and Echbara licenses to dovetail into the previous season's soil traverses. This will provide full coverage across both licenses at 800 m x 50 m spaced sampling and identify any new artisanal workings.
An excavator has been mobilised from N'Djamena to the Dorothe camp and an 8 km in-fill and extension trenching programme planned over the Dorothe prospect.
The trenching is designed to test for extensions and strike continuity from previous season's trench intersections within the Dorothe Artisanal Pitting Zone (DAPZ) as well as testing below a large area of sediment cover potentially concealing mineralisation below.
Trenching will also test for strike extensions of the Dorothe Main Vein zone (DMV) southwards, where artisanal workings occur approximately 1 km south of the Dorothe prospect.
During the intervening wet season shut down, artisanal miners have identified new mineralised zones within the Dorothe prospect, and opened new workings over 25 m strike and up to 10 m vertical depth.
The new workings coincide with reported intersections in previous trenching. Surface mineralised samples are rich in galena and secondary copper minerals.
