The Phase 1 exploration program comprises; geological mapping, hand auger soil sampling, manportable percussion drill soil sampling, rock chip sampling, portable XRF analysis, and laboratory analysis for gold over the OPQ gold target.
The program will comprise orientation geochemical surveys over the area of outcropping gold-bearing quartz mineralization, including both soil and rock chip sampling. Soil sampling will be initially conducted on a 50m x 25m spaced grid over the entire property; locally, samples will be collected on 12.5m spacing in the area of the known mineralized quartz vein.
Planned work includes re-establishing the access road, locating the prospects and rock chip sampling. Drilling of selected sites is an option for later in the season if field results are positive.
(Alliance News) - Bezant Resources PLC on Thursday said assay results from rock chip sampling at its Buffalo project in Zambia found high grade values of copper.
These soil results follow up earlier rock chip sampling results from April 2019 which revealed grades of up to 29 g/t gold.
High-grade rock chip sampling results of up to 46.4g/t gold; hard-rock artisanal workings defined over 1.2km strike length within the newly acquired license, occurring within a broader 12km strike target corridor of anomalous gold rock chips and artisanal workings
Savannah noted that rock chip sampling results from the Gaddamah prospect have shown grades of up to 5.7 per cent copper and 3.7 grammes of gold per tonne.
Perth, Australia, July 26, 2013 - (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 first phase exploration field programme covers trenching, rock chip sampling, mapping and clay alteration studies within the known mineralised trend, in addition to systematic soil sampling to define extensions to the trend to the east, south and north.
In the late 1970s, chip sampling on the property yielded up to 0.10 pounds per ton uranium over widths up to 15 metres.
They include: emergency repairs, owner occupied co-ops and condos, areas where lead based paint was removed and certified lead free by a licensed inspector and areas certified lead free via XRF analysis or paint chip sampling by a certified lead testing firm.
Reconnaissance chip sampling at "La Patriota" returned a best result of 81.4 g/t Au and 86 g/t Ag over a 1m chip sample, with 7 of the first 18 samples collected on the prospect returning greater than 20 g/t Au.
