Drilling Fantastic, Stream Sediments SensationalHello Mates,
Teck mining 0.26% copper and HPY drilling 120 metres of 0.26% copper with a section close to 0.7% copper over 27.5 metres, with 4.8 gram silver. Fantastic.
The stream sediments caught my fancy. Undoubtly impressive. Cheers.
Stream Sediment Sampling Surveys
Stream sediment surveys are very useful for mineral exploration because of greater dispersion in the stream environment. Greater dispersion means greater ability to detect an ore body from a greater distance. A drainage basin is an area with a network of streams like the branches of a tree: smaller streams join together leading into larger and larger streams. Geochemical values of sediments located downstream are an indication of rock geochemistry, or potential ore deposits, located upstream.
Unfortunately, an anomaly discovered downstream in a large drainage basin gives only a general idea of location of the source. The source of the anomaly could be anywhere within the drainage basin. This is why it is a good idea to sample all the streams in a drainage area. Typically a stream sediment survey will attempt to sample both sides of every stream fork. In this manner, if an anomaly occurs on one side and not on the other, only the fork with the anomaly needs to be considered in locating the source. The trail of anomalies forms a path upstream towards the source. Generally the values will increase towards the source, and then drop to zero or background values upstream from the source.
1. Approximately 1.5 kilometres to the southwest of Zone 1, samples of quartz vein material have returned values of 3.34%, 1.74% and 1.04% copper and up to 0.021% molybdenum, and 5.78 g/t silver. Eight stream sediment samples in this area have confirmed previous positive results of 887 ppm (parts per million) to 1625 ppm copper and expanded the area of interest. New sampling has returned 190 ppm to 776 ppm copper including 414ppm and 592 ppm copper and 1.74 to 29.4 ppm molybdenum from several stream tributaries. This area is underlain by favorable Bethsaida phase intrusive rock and an induced polarization geophysical anomaly approximately 800 by 600 metres in dimension that is thought to represent a very prospective untested target.
2. In the southern portion of the Rateria property, the Sho claim covers an area approximately two by three kilometers in dimension and is within an important regional magnetic low believed to map out the younger and more productive phases of the Guichon batholith. This prospective area also occurs near the intersection of the east-west trending Skuhun Creek and north-south trending "Corridor" fault. The regional magnetic and structural setting is similar to that occurring near the major mines in production to the north. The Company has not conducted a significant amount of work in this area to date.
The main Sho prospect is part of a larger mineralized structure that has been previously trenched by the Company. Here, systematic chip sampling covering approximately 15 metres by 4 metres in dimension averaged 1.49% copper and 8.4 g/t silver. In 2010, the Company continued prospecting approximately 400 metres to the south of the trench. Rock sampling has outlined a northwest trending mineralized zone for over 250 metres in length and 50 to100 metres in width that remains open in length and width. Twelve grab samples of mineralization within this zone returned from 0.20 to 2.84% copper and up to 12.8 g/t silver. Seven samples contain from 0.05 to 0.11 g/t gold. Seventeen (17) widely spaced stream sediment samples on this claim have returned values from 33.7 to 427 ppm copper, with nine sample greater than 250 ppm copper and four samples greater than 400 ppm copper. One silt sample located 200 metres downstream of the Sho trench returned 33,900 ppm (3.4%) copper, 68.9 ppm molybdenum and 4.09 g/t silver. Historical silt sampling results include values of 452ppm, 496ppm, 524ppm, 575ppm and 951ppm copper. Together, these stream sediment and rock sample results are thought to be very positive for porphyry copper exploration, and this large area has not had systematic modern induced polarization (IP) geophysical surveys completed. The Company is very encouraged with the results from this under explored portion of the Rateria property and further exploration is planned.
