Midlands picks targets

A soil geochemistry survey by Midlands Minerals (MEX-V) at the Itilima property in the Lake Victoria gold belt of Tanzania has pointed to a gold anomaly surrounding known mining workings.

The survey has defined an area measuring 4 km long and 2 km wide with gold values well above background concentrations. It follows a trend of surface mine workings made by small-scale craft miners in the area.

The survey combined cyanide-extraction tests on saprolite soils and termite mound material with mobile metal ion extractions on transported soils. Both methods showed similar distributions of anomalous gold concentrations in the materials that were sampled.

Previous mapping in drainage valleys showed that the gold occurrences at Itilima were mainly in quartz veins in felsic volcanic rocks interbedded with more ductile metamorphosed sediments. The veins were surrounded by carbonate and pyrite alteration.

Altogether a 2.8-km strike length of felsic volcanics is known, with gold mineralization concentrated on one limb of a vertical “Z” fold. Gold grades in grab samples ranged from a few grams to 41 grams per tonne.

Follow-up geochemical surveys are planned and a reverse-circulation drill will be brought on-site later in the year.
