Ampella Mining has announced new assay results from its shallow infill drilling programs at its mine in Burkina Faso as the "highest and widest gold grades encountered to date."
In a statement to the Australia Securities Exchange Ampella said that infill drilling results at the Konkera included 17 metres at 17.2 grams per tonne of gold, including 8m at 35.3 g/t gold.
The drilling was part of an intensive $13 million exploration program.
See company statement below:
Ampella Mining Limited (ASX: AMX) is pleased to announce additional new assay results from shallow infill drill programs at the Konkera 1.2Moz JORC Code Compliant Inferred Gold Resource (18.5Mt at 2 g/t gold), as part of an intensive $13 million exploration program being undertaken in 2010 at the Batie West Project in Burkina Faso, West Africa (Fig. 1).
Additional shallow infill drill results have now been received from Konkera North, Konkera East and Kouglaga Prospect areas which form part of the now 5,000m long Konkera gold zone on the Tiopolo Permit (Figs. 2 and 3).
At Konkera North (Fig. 2), exciting gold assays were received for an additional 8 reverse circulation drill holes, some with diamond drill-core tails, for a total of 1,311m of drilling (Tables 1 and 2). Results confirm the continuity and high tenure of gold mineralisation at the Konkera North region of the resource with the best results received from KNRD337 which intersected 66m at 4.0 g/t gold, including 26m at 8.1 g/t gold. Assay results for 2 diamond core tails remain outstanding but will be released to the market when available.
At Konkera East and Konkera Main (Fig. 3), where a stacked lode system exists, gold assays have been received for 16 reverse circulation drill holes, for a total of 1,791m of drilling (Tables 1 and 2). Two drill holes ended in mineralisation and will require re-entry and diamond tail extensions. In drill hole KERC003 (Tables 1 and 2; Fig. 3) multiple economic stack lodes were intersected including the highest gram-metre intersection from all drilling to date at the Konkera Prospect which included 17m at 17.2 g/t gold.
In addition, at the Kouglaga Prospect, gold assays were received for three shallow reverse circulation drill holes, two with diamond tails, for a total of 618m of drilling (Tables 1 and 2) from adjacent to the high grade oxide zone. Results from these three drill holes were mixed but indicate that some lower-grade gold mineralisation exists to the south of this zone where previous drilling had intersected 18m at 10.3 g/t gold and 11m at 10.5 g/t gold. Mineralisation remains open to the north.
The best gold intercepts received in the current set of assays from shallow infill drilling at the Konkera Prospect are presented in Table 1 above. These new results further complement previous assays where best intersections included (ASX: 1 September 2010):
KNRC250: 29m at 7.6 g/t gold, including 20m at 10.6 g/t gold; and
KNRC251: 21m at 6.3 g/t gold, including 9m at 9.4 g/t gold.
Resource upgrade work at the Konkera Prospect is progressing well with 3 multi-purpose rigs currently on site. These rigs are undertaking shallow infill drilling (top 100m vertical) on the Resource to take it from a JORC Code Compliant Inferred Resource into the next categories of Measured and Indicated. Additional deeper drilling from 100m vertical down to 200m vertical will also be undertaken across the Konkera Prospect to add significant potential gold ounces to the current Resource, which remains open at depth and increases statistically by 0.5 g/t gold over the first 100m vertical depth. A new proposed resource upgrade is expected to be released to the market in early 2011 and will include drilling results across the entire 5km strike length of known mineralisation from Konkera, "The Gap" and Kouglaga Prospects.
These exploration programs form part of an aggressive $13 million exploration program
for the current calendar year 2010 at the Batie West Project. Proposed drill programs include upward of 80,000 metres of conventional drilling (reverse circulation and diamond drilling) and 35,000m of auger geochemistry drilling.
