Newport Gold Inc. has announced an upcoming drilling programme to test two airborne geophysical conductors at its wholly owned Manitou claim, located in the Burnt Basin property in the Greenwood Mining division in British Columbia, Canada.
The company is planning to test two flat-lying conductors, located at a depth of 50 and 300 ft below the surface on its Manitou claim. The latter conductors were a result of conducting an airborne survey over the company’s former property, and retaining the only claim hosting the conductors.
An interpretation by Condor Consulting stated that the flat-lying conductors were modelled at the depths stated above, but that neither the thickness of the conductors, nor their lateral extent, could be estimated. Condor also stated that the interpretation was based on what was energised by the survey and did not necessarily reflect the full potential of the conductors.
The two main targets are the horizontal anomalies which cover some, if not all, of the mineralisation, at a 60 ft depth, and another deeper zone at about 300 ft. The latter zone is presumed to be another mantos zone similar to what was found at the Gilman mine in Colorado, which hosts many mantos zones.
In 1927, the Halifax claims were worked on at a depth of 60 ft, and the mineralised area was said to occur entirely within limestone and to extend for a length of at least 500 ft. The upper zone is described as being galena, sphalerite and pyrite in a quartz gangue, while the lower zone is said to contain pyrite and chalcopyrite. Development work included open cuts and a tunnel located below the outcrop. A sample of the ore extracted assayed 20.5% zinc, 17.7% lead and 10.8 oz/t silver.
Dr Donald Kohls, a former director of the company and previously in charge of the Goldfields Mining exploration programme which resulted in the discovery of several multi-million oz gold mines, felt strongly that the airborne anomalies represented manto deposits. The latter conclusion was partly due to the presence in several areas on the surface of high-grade values of both copper and silver, which make up the pipe portion of these deposits. He had studied the multi-million t Gilman deposit in Colorado, a classic mantos deposit. This interpretation explains not only the host rocks, but the presence of the very high values of copper and silver in the immediate area.
Dr T. Hoy, an expert in base metal deposits, has visited the property and also considered it mantos-style mineralisation. He thought the presence of high-grade values of copper and silver in the area east of the Halifax mine was perhaps the keel zone of a mantos deposit.
In addition, the company is planning to follow up on the Gold Knoll property discovered in late 2007. It was discovered following up on a strong soil geochemical anomaly. Quartz veins in that area returned values of 43.07 g/t gold and 42.78 g/t gold. The former sample also carried 204 g/t silver and about 1% lead with minor zinc, while the latter sample carried 46 g/t silver and .38% copper. The showing is situated northeast of the airborne conductors and northwest of the Eva Bell mine, which is located on the east part of the company’s property. Of all the samples taken in the past by the company, this was the first time high gold values have been found with this amount of grade-wise base metals.
