AMN - CHAD: High-grade gold results from Dorothe

IronRidge Resources has received multiple high-grade gold results from extensional and infill trenching at the Dorothe prospect in Chad, Central Africa. The company has now defined five large, coherent gold targets over 500 metres to 1.2km in strike length and 100 to 200 metres in widths with targets still open along strike.

Best results for the 200 metre infill and extensional trenching program are 4 metres @ 18.77 g/t gold including 2 metres @ 36.2 g/t; 32 metres @ 2.02 g/t including 18 metres @ 3.22 g/t; 4 metres @ 4.25 g/t including 2 metres @ 6.24 g/t; and 12 metres @ 2.53 g/t including 6 metres @ 4.1 g/t and 2 metres @ 6.14 g/t.

There have been 6,608 metres of results received to date for an overall 9,360 metres of trenching completed, of which 8,984 metres have been sent to a laboratory for assay during the last field season.

Two dominant mineralisation settings have been interpreted from improved geological understanding - steeply east dipping 'Main Vein' and shallow west dipping 'Sheeted Vein' targets.

Additional results are pending for 2,376 metres of trenching completed to the west of the 'Main Vein Swarm' and the remainder of Trench 29.

The trenching program has confirmed the extension of mineralisation below cover and the continuity of anomalous intervals between previously reported wider spaced trenches. This provides confidence in the continuity and scale of the mineralising system at Dorothe.

IronRidge chief geologist Len Kolff said, "Results of the infill and extensional trenches received to date have defined multiple, high-priority gold targets at the Dorothe prospect.

"The results are highly encouraging, not only due to the widths and grades intersected in 'fresh rock' but also because they demonstrate continuity and scale of the target zones.

"Additionally, the Tekton team has discovered gold mineralisation and proven extensions from known mineralised zones that extend 'blind' undercover sediments, vindicating the infill trenching strategy and demonstrating further scale potential and exploration upside.

"Detailed trench logging has enhanced our understanding of structural, lithological and vein-type controls on mineralisation; providing further encouragement that we are dealing with a potentially large mineralised system."

Fieldwork will recommence in October 2018 with a ground geophysics Induced Polarisation survey planned over Dorothe to further define drilling targets at depth in conjunction with surface trenching results.

Len Kolff said, "The IP survey is designed to detect disseminated sulphides potentially associated with gold mineralisation at depth and highlight potential structural corridors along which mineralisation occurs.

"This will provide an additional control on target definition prior to drilling program design whilst testing for down-dip extensions of the surface mineralised footprints defined."

IronRidge acquired 100% of Tekton Minerals Pte Ltd of Singapore including its projects covering 900 square kilometres in Chad and its team to advance the Dorothe, Echbara, Am Ouchar, Nabagay and Kalaka licences.

The company also has properties in Gabon, Côte d'Ivoire and Queensland, Australia.
