Lati Permit Geology

The 246 square kilometre Lati Permit, located in the Boromo greenstone belt, covers a major north-south shear zone and a number of known but under-explored prospects as well as two active artisanal mining areas.  The Lati permit is about 150 km by road, of which about 100 km is paved, west of Ouagadougou, and lies 50 kilometres north of the Poura Gold Mine.  Lati was previously explored by the United Nations Development Program (“UNDP”) and the Burkina Faso Office of Mines and Geology (“BUMIGEB”) for volcanic-hosted massive sulfides (“VHMS”) similar to the Perkoa zinc deposit, as well as by Carlin Resources, Semafo  and Incanore Resources for gold.

Prior exploration included airborne geophysics, soil geochemistry, trenching, and drilling.  Several anomalous areas that were not followed up include: Prospect 1 where a gold-in-soil anomaly (1000m by 200m) in the northern part of the permit yielded three samples over 1 gpt Au with a peak value of 6.5 gpt Au and a UNDP prospect that reported 12m of 2.45 gpt Au in a diamond drill hole; and the Kwademen artisanal mining area where reported gold mineralization over an area of 1250m x 250m with isolated values up to 65 gpt Au occurs in quartz veins and veinlets in a sheared granites and felsic volcanics.

The Prospect 1 area is the site of rapidly expanding artisanal workings on the east side of the permit. A previously known site has recently expanded from 500 metres by 50 - 200 metres to 1200 metres by 50 - 500 metres over the last 14 months. A second  new active artisanal site spans an area 500 metres long by 100 to 200 metres wide and lies 2.5 kilometres to the northwest of the previously known artisanal site. These sites lie along the sheared contacts of a north-northeast trending 1500 metre wide band of bimodal volcanics  surrounded by felsic intrusives. Mineralized quartz veins are common through this area, ranging from thin stockworks to metre-scale structures associated with regional scale shearing and fracturing mainly in mafic volcanic rocks. Artisanal  miners are working over and extracting particulate gold from the top  1 to 3 metres of surface material over the majority of this area. Recent Indigo grab sampling within the expanding artisanal site returned values to 11 gpt Au.

A small soil grid at Prospect 2 located a 1200 metre long by 50 to 600 metre wide gold-in-soil anomaly on the eastern side of the grid. Twenty of the 241 soil samples returned gold values greater than 50 ppb Au, highly anomalous in this region.

Indigo is currently completing a detailed sampling grid for soil and quartz float over the entire 5,000 metre long by 1,500 metre wide Prospect 1 area in advance of follow up trenching and reverse circulation drilling.
