Eleckra Mines (ASX: EKM) owns 100% of the Yamarna Gold Project, a sizeable tenement package totalling approximately 3,600km2, covering the majority of the Yamarna greenstone belt. Eleckra's uranium prospective tenement portfolio around the Yamarna region covers an area of approximately 2,000km2.
Eleckra Mines (ASX: EKM) has reported further high grade results from Central Bore which support the first and second batches of assays from its current 10,000 metre RC drilling program at its 100% owned Yamarna Gold Project, with intersections extending gold mineralisation to the south, and it remains open along strike.
The Yamarna Project is located approximately 150km east of Laverton on the eastern edge of the Yilgarn Craton and within the Yamarna Greenstone Belt in in Western Australia.
The company said the third batch of assays indicate southern extensions of gold mineralisation at Central Bore and the drill rig has been relocated to Central Bore to follow up the southern extension.
Visible gold has been panned in the first holes of the follow up drilling at Central Bore and 24-hour bottle roll cyanide leach and gravity separation testwork has started.
Eleckra has completed eighteen holes for 3,594 metres in the current phase of RC drilling at Central Bore. Assay results from the third batch of six RC holes have been received returning "exciting" elevated gold values of up to 22.2 g/t Au over a one metre interval.
Significant results include: 1 metre at 21.7 g/t Au from 173 metres; 2 metres at 12.2 g/t Au from 136 metres including 1 metre at 22.2 g/t Au.
Eleckra said these results are particularly significant as "the mineralised intercept with 2 metres at 12.2 g/t Au comes from the most southern hole, 10EYRC16, indicating the mineralisation remains open to the south."
High grade gold mineralisation (>10g/t Au) has now been intersected over a strike length of over 500 metres.
Due to these high grade gold assay results, Eleckra has temporarily suspended the Hann drilling program and moved the drill rig back to Central Bore to test for extensions further to the south of the recent drilling.
Eleckra plans to test a further 200 metres to the south of holes drilled to date potentially significantly extending the strike of the mineralised zone.
Three out of six holes drilled in the next phase program at Central Bore have so far intersected mineralisation with abundant visible gold being panned as follows:
- Hole number 10EYRC0066 between 47 metres and 49 metres
- Hole number 10EYRC0067 between 201 metres and 204 metres
- Hole number 10EYRC0069 between 130 metres and 131 metres
Samples will be sent to the laboratory for assay and results will be released as they become available.
In addition, Eleckra has selected 47 drill samples from the mineralised intercepts at the Central Bore deposit for 24-hour bottle roll cyanide leach testwork.
Eleckra is also commencing gravity separation testwork on mineralised samples from Central Bore in order to determine gold recovery through a gravity circuit.
The Central Bore maiden resource is expected to be completed in second half of 2010. The third batch of assays also included 6 reconnaissance holes from Byzantium, and 19 holes from Hann.
The 3rd batch of results included 19 holes from the two southern-most lines at Hann prospect. Five holes returned grades above 0.5 g/t Au. The results from the remaining 20 holes are expected in late June 2010.
At Byzantium, three holes on one line tested the western base-metal anomaly and three holes. The best intercept of 1m @ 0.8 g/t Au associated with 0.3% Pb (assayed with Portable Niton XRF) in hole 10EYRC0019.
The company considers that the area around Byzantium and Central Bore has potential for hosting volcanogenic massive sulphide (VMS)-style of base metal deposits.
The nearest VMS deposits to Yamarna are Jaguar and Teutonic Bore located approximately 250km NNW of Kalgoorlie.
Three holes were drilled to test the eastern anomaly at Byzantium. Weak gold mineralisation was intersected in all three holes associated with a narrow 3m-wide basalt unit within an intermediate volcanoclastic unit. The best result was 4m at 0.58 g/t Au from 60m in hole 10EYRC0022.
Ian Murray, executive chairman, said to date three soil anomalies generated in 2009/2010 have yielded anomalous to ore grade gold mineralisation and "this represents an excellent success rate and supports the case for further detailed soil geochemistry to identify additional mineralised horizons."
