HIGH GRADE GOLD SOIL SAMPLE RESULTS FROM SABOUSSIRE
HIGHLIGHTS
- Large +50ppb gold anomaly identified at Saboussire extending 2km North/South by 1km East/Wests
- Total of 271 anomalous samples assayed >20 ppb Au, including:
- 17 samples @ > 100 ppb Au with peak value of 9610 ppb Au (9.6 g/t Au)
- 34 samples @ 50 - 100 ppb Au
- 220 samples @ 20 - 50 ppb Au
- Two new zones of interest identified with expanded works program to shortly commence
Indiana Resources Limited (ASX: IDA) ('Indiana' or the 'Company') is pleased to report excellent high grade soil samples from the Saboussire and Kenieko licenses in West Mali (Figure 1).
At Saboussire, a large +50 ppb gold anomaly extending over 2 kilometres in a north-south direction and 1 kilometre in an east-west direction was identified in the south west area of the licence. In the central portion of the licence, a 9610 ppb Au (9.6 g/t Au) result was returned with this area now earmarked for immediate follow up.
The soil geochemistry programme had been designed to test and extend existing Government soil sample anomalies on the licence and test the strike extent of the strong mineralised trend identified at Kossanto and further south at Koussikoto. Soil sampling totalling 1,253 samples was completed over 3 individual areas of the Saboussire licence on a nominal 200m x 100m grid pattern.
Assay data has now also been reviewed in relation to the magnetics and interpreted geology. As a result, two additional areas have been highlighted at Saboussire that require additional sampling to follow up on the anomalous trends and the high-grade result (see Figures 2 and 4). An additional programme has been designed for immediate implementation that includes approximately 1,200 samples on a 200m x 100m grid to infill and cover the new areas identified.
The Saboussire licence covers an area of 100 km2 and is located on the Main Transcurrent Zone. The Main Transcurrent Zone is interpreted to be one of the major structures which controls mineralisation in Western Mali and Eastern Senegal.
Soil sampling completed at Kenieko Nord totalled 606 samples over areas not previously sampled and were completed on a 400m x 100m grid pattern. The soil sample results returned have identified narrow spot highs and review of both the magnetics and interpreted geology have largely shown the underlying geology covers magnetic lows, commensurate with the interpreted sedimentary underlying geology.

The Company is now reviewing existing data for this license and considering the potential to conduct some basic mapping in the areas of the highest values. See Figures 5 and 7.
Kenieko Nord is considered to be an excellent geological and structural location, within the highly prospective Kenieba Inlier of Western Mali, which hosts a number of multi-million ounce gold deposits, including the Loulou 12.5Moz deposit (Barrick Gold) and the Sabodala 6Moz deposit (Teranga Gold).
Indiana, through its wholly owned subsidiary Mukuyu Resources Limited ('Mukuyu'), has an earn-in agreement with FIMOCO SARL, ('FIMOCO') and the option to acquire up to an 85% stake in Saboussire.
Indiana Chairman, Bronwyn Barnes commented:
"These are very encouraging results and further exploration work is certainly warranted. There is strong potential for the prospective trends to extend over considerable strike lengths and this work can be done quickly and with minimal expenditure. We have now assembled a highly strategic landholding in Mali located on two highly prospective mineral corridors that host several multi-million ounce gold deposits. We are now focused on kicking off the next phase of exploration on a number of priority targets as soon as possible."
This ASX release was reviewed and authorised for release to the market by the Board of Indiana.
