Second Exploration Phase Completed on Persada Tenement
Perth, July 26, 2013 AEST (ABN Newswire) - The Board of Western Mining Network Ltd (
ASX:WMN) is pleased to announce that assay results have now been received from the second phase of exploration for the semi detailed geological mapping, float rock chips samples, outcrops via rock chip sampling and trenching within the Persada Tenement. The Persada Tenement is located northeast of Palu in Central Sulawesi, between Toli-toli and Buol. It is approximately 50km east of Toli-toli and covers 5,000ha.
There is an existing access road to the Tenement via Lakea village road, west of the Buol-Toli-toli highway. The second phase of exploration has been undertaken as a follow up to previous Stream Sediment (SS) Exploration conducted in May 2013 which revealed anomalies for Au. Two prospective blocks were identified for additional exploration follow up; Block A ~480ha & Block B ~450ha.
Several rock chip samples taken from either in situ outcrops or float were collected during geological mapping. A total of 16 selected samples were used for assay and 4 samples were used for petrographic analyses of the mineralisation and alteration.
All samples were analysed by PT Intertek Utama Services, a reputable mineral laboratory in Jakarta. Rock samples were analysed using Fire Assay (Method code: FA 51) for Au with detection limit at 0.01 ppm. Cold vapor AAS (Method Code: CV02) were used for Mercury (Hg) determination and ICP-OES method (Code: IC01) were used after aqua regia digest for Ag, As, Bi, Cu, Mo, Pb, Sb, Te & Zn.
The highest Au content is from float sample RF-009 (1.58g/t Au), followed by outcrop sample OC- 010 (0.32g/t Au).The gold coincides with high arsenic in RF-009 (8,870ppm As) and OC-010 (5,420ppm As).
RF-009 is a mineralised float sample of hydrothermal breccia with disseminated pyrite from the Salutu River(Fig 3). OC-010 is from an outcrop of silicified sandstone with disseminated pyrite and arsenopyrite(Fig 4 in link below).
Ongoing exploration at the Persada tenement will include:
- Topographic & Grid Mapping
- Grid Pattern Soil Sampling using the MMI method for analysis
- Detailed Geological Mapping & Sampling
- Petrography & Mineragraphy Analysis
- Assay
