ROUYN-NORANDA, QUÉBEC--(Marketwired - Oct. 2, 2017) - Chibougamau Independent Mines Inc. (TSX VENTURE:CBG)(STUT:CLL)(OTC PINK:CMAUF) is pleased to provide shareholders with a short summary of results from detailed structural mapping and channel sampling undertaken on Chibougamau Independent's 100% owned Berrigan property located 4 km northwest of the Town of Chibougamau, Quebec.
Extensive drilling over many years cut numerous intersections of gold, zinc, silver and lead. Due to the complex structural controls of the mineralization, it has been difficult to connect the intersections into individual mineralized bodies. It was decided to undertake detailed structural mapping in the area of the Berrigan adit to try to get a handle on the various directional controls of mineralization.
Mapping and channel sampling of select mineralized exposures were undertaken first in 2016 (the 71300 sample series) and then in 2017 (the 25000 sample series) perpendicular to the mineralization. The detailed mapping of the 150 m x 100 m area shows that the bedrock consists principally of Cummings Sill Complex peridotite. Mineralization consists of pyrrhotite, sphalerite, galena, lesser pyrite and occasionally minor chalcopyrite in deformed sills which create a series of large peridotite blocks (up to 22 m wide) with minimal displacement.
The three principal directions of mineralization were mapped as: 1) north-south (N-S) to north-northeast (NNE) - south-southwest (SSW), 2) east-northeast (ENE) - west-southwest (WSW) and 3) north-northwest (NNW)-south-southeast (SSE).
In addition, a mineralized area where the NNW-SSE and NNE-SSW structures intersect was noted, mapped and channel sampled.
The following is a listing of some of the more significant assay values listed by structural control direction. Only exposed mineralized areas were samples. No trenching to define the total mineralized widths was done.
Results of mapping and channel sampling on Berrigan adit area (Main zone)
|Structure||Sample #||Length (m)||Au (g/t)||Ag (g/t)||Cu (ppm)||Zn (%)||Pb (%)|
|NNW-SSE and NNE-SSW junction||E25051||0.6||1.37||6.20||1737||5.95||0.2|
|N-S to NNE-SSW||E25060||1.3||5.25||107.80||893||6.84||10.05|
|Note: 31.1 g/t = 1 Troy Ounce|
Now that we have a better understanding of some of the directional controls of the mineralization in the Berrigan adit area, we hope to be able to recompile the historical and recent drilling in order to define the mineralization in three dimensions along the principal structural controls.
Laboratory and Assay Methods
Chibougamau Independent Mines' channel sampling including the quality assurance/quality control program is performed internally by Chibougamau Independent Mines personnel under the immediate supervision of Chibougamau Independent Mines project geologist. The samples are prepared in the field, they are tagged and sealed in plastic bags and are delivered directly by Chibougamau Independent Mines personnel to Expert Laboratories Inc, located at 127 Boulevard Industriel, Rouyn-Noranda. The laboratory conducts all aspects of the sample preparation including drying and crushing to a minus 100 mesh screen size and the processing of a 300 gram sub sample for pulverization to a nominal minus 200 mesh size with the remaining crushed reject material being retained for storage. For gold assaying, a 29.16 gram sub-sample of the pulp (1 assay-ton) is taken, fused following the standard procedures used in a fire assay method. The gold content of all samples is determined using atomic Absorption Spectroscopy. Samples containing greater than 1gpt gold are subjected to a re-assay whereby the gold content is determined using a gravimetric fire assay method. For base metal assaying (copper, lead, zinc including silver) a 0.5g sample is initially treated by aqua regia digestion with nitric and hydrochloric acid and subsequently analyzed by a spectrometer of atomic absorption finish.
Analytical accuracy and precision are monitored by the routine insertion of blanks, duplicates and reference accredited low/high grade standards at 20 sample intervals in Chibougamau Independent Mines' sample stream. This is in addition to the routine blanks, duplicates (gold, silver, copper, lead and zinc) and accredited standards insertion by Expert Laboratories during the course of the assaying process.
Field work was conducted by Mostafa Amrhar, Phd., Geo. and Luc Rioux, Geo. and this press release was written by Jack Stoch, Geo., President and CEO, for Chibougamau Independent Mines Inc. in his capacity as Qualified Person (Q.P.) under NI 43-101.
