Second Exploration Phase Completed on Persada Tenement
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
