BEDROCK GOLD SUMMERY

Prospecting, mapping, rock/soil geochemistry and archive data compilation identified 5 targets for more detailed follow up.

The Laminaia/ Ranongo Ridge target was prioritised  and detailed work including detailed soil geochemistry, geophysics, mapping, trenching an pitting defined a target 7 km long 400 m wide.

This target was tested by an initial 1600 m scout drilling programme which identified a sequence of  auriferous magnetic schists/ pegmatites/quartz veins associated with a major shear zone developed along the western flank of the Ranongo ridge.

Given an estimated strike length of 7000 m and a width of  400 m ( based on the extensive exploration work) and grades of ~+3 g/t, the potential bedrock resource is +2 million oz Au.

BEDROCK GOLD

Considerable interest in mineralised saprolites which appear to be supergene enrichment of an underlying primary source.

Five targets have been prioritised for continuation of source rock exploration

The main shear zone believed to be hosting the gold mineralisation has been defined in Target 1 covered extensive eluvial gold mineralisation which can only form over a mineralised underlying primary gold bearing rock.

Magnetite schist which have been identified after extensive study in Ranongo North (priority 1) related to the main shear zone hosting auriferous quartz veins, pegmatite and late granitoids have also been exposed in Manahua (Priority 2) by artisanal miners chasing gold-rich quartz veins.

Priority 3 have a known elluvial deposit currently mined by artisanal miners and this is believed to be sitting over a primary source for the gold.

Priority 4 returned the highest gold value from stream sediment sampling in the entire Loko Hill Licenses. No further work done on gold.

TRENCHING

3262 meters.With increasing geological information and general understanding of the mineralisation in Ranongo North, the magnetite schist-gold association theory is very strong for which a geophysical method has been propose for delineating the host rock. To test the applicability of magnetic geophysical method on the target, a hand held magnetic susceptibility meter was use across a trench that intersects magnetite schist zone. The results show that the magnetite schist zone is clearly defined by the mag susc meter which justifies the use of cheap ground magnetometer survey to define the extent of the magnetic zone and shear zone in the Ranongo north. The high grade zone in TR1042800 also coincides with magnetite schist zone containing 5g/t @ 115-116m in TR1042800 and a coherent zone containing 4m interval with 1.35 g/t Au between 114-118m. Similar lithology in TR1043980 retuned 10g/t @ 81-82m but due to the narrow and isolated zone in this trench, no further work was conducted in the trench. TR1043980 – Magnetite schist zone contains 4m interval with 2.63g/t Au with maximum grade of 10g/t Au between 80-84m. This zone also corresponds with active surface elluvial/saprolite mining by the local artisanal miners targeting mainly the magnetite schist.

RANONGO SOUTH DRILLING

Mineralisation in Ranongo South is interpreted to be associated not only with the main north-south shear zone but also with later stage mafic dykes and quartz veins.

These dykes and quartz veins appear to “follow” faults that displace the main shear zone.

Both the dykes and quartz veins are mineralised with some samples taken of mineralised quartz veins returned >100 g/t Au.

Holes 8, one of the holes in the north consist of the highest grade intercepts with a 7g/t @ 59-60m and a 3.5g/t @ 62-63m coinciding with a magnetite schist zone.
