Aviva Corporation's High Grade Gold Discoveries Keep On Coming From Bushiangala

Aviva Corporation (ASX: AVA) is further reinforcing the continuity and high grade nature of known gold mineralisation at the Bushiangala Prospect in West Kenya.

The company has delivered additional high grade intercepts from follow up diamond drilling on prospects at the Kakamega Gold Camp, which continues to confirm the validity and predictive nature of the geological model.

Notable intercepts from Bushiangala include 2.58 metres at 6.8 grams per tonne (g/t) gold from 56.32 metres, 9 metres at 10.89g/t gold from 58.25 metres, 1.63 metres at 7.57g/t gold from 75.3 metres, 1.04 metres at 3.01g/t gold from 127.63 metres, and 3.2 metres at 19.85g/t gold from 2.66 metres.

Importantly, mineralisation is being intersected where predicted by the geological model constructed by in-house and independent consultants.

Assays from a further four holes are still awaited.


At the Kimingini Prospect drilling is continuing to test for strike repetitions and down plunge extensions of mineralised shoots.

The Kimingini shear-hosted model has been confirmed.

While intersecting a number of mineralised zones, the main lode has once again to a large extent been stoped out by a late, buck white quartz vein.

Drilling delivered a best intercept of 0.5 metres at 5.22g/t gold from 168.89 metres.

Kakamega Gold Camp

Follow up of geochemical anomalies along the Liranda Lineament continues with mapping, soil, rock chip and auger sampling confirming and further defining anomalies.

An orientation induced polarisation survey at Bushiangala, Kimingini and Makutchi has been completed.

Data suggests gradient array induced polarisation will be useful in mapping the important contact, in terms of mineralisation, between the volcanic and sediments along the Liranda Lineament.

Reprocessing and a detailed re-interpretation of magnetic data around the Kakamega Dome have resulted in a better understanding of the structural framework and kinematics.

Importantly, this has allowed better ranking of existing targets and identified a number of new structural/magnetic targets for follow up.

Drilling continues to test the southern margin of the Kakamega Dome and in particular the Liranda Lineament.

Drilling is currently underway at the Ibwali prospect, located around 1 kilometre to the east of Bushiangala.

Lake Zone

Drilling has also begun at the Ramula prospect around 25 kilometres southwest of Bushiangala.

The prospect is the site of previous colonial and artisanal activities and its prospectivity is supported by anomalous rock chip and gold-in-soil anomalies and open hole percussion drilling by previous explorers. Assay results are awaited.

Next exploration steps

Aviva continues drilling priority prospects at pace using two diamond drill rigs.

Work in the Kakamega Gold Camp will consist primarily of follow-up drilling of known prospects that have previously returned encouraging gold intercepts.

Aviva's focus remains on drilling targets located close to regionally significant reactivated syn-tectonic extensional structures with demonstrated gold endowment, such as the Liranda Lineament.

Detailed geological mapping and geochemical surveys will also continue to define drill targets in areas where previous work has demonstrated prospective geology, structure, alteration and gold mineralisation.

Work in the Lake Zone will comprise both drilling of prospects considered to have significant size potential, as well as geological mapping and geochemical sampling to define additional drill targets.

$20m sale of Kenyan assets

Aviva Corporation has struck a deal with Barrick Gold Corporation (NYSE: ABX, TSX: ABX) to sell its Kenyan gold and base metal assets, injecting $20 million into the company.

The company has entered into a binding sale and purchase agreement to sell Aviva Mining Kenya to Barrick subsidiary African Barrick Gold, one of the five largest gold producers in Africa. This acquisition represents African Barrick Gold's first move into Kenya.

The funding from the sale will add to the over $1 million in cash held by Aviva at the end of the June 2012 quarter, and allow the company to assess its strategic growth options for its coal-based projects in Botswana.
