VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 16, 2013) - International Northair Mines Ltd. (TSX VENTURE:INM) ("Northair" or the "Company") announces that Focus Ventures Ltd. (TSX VENTURE:FCV) ("Focus") has terminated its option to acquire an interest in the Company's El Reventon silver-gold property ("El Reventon" or the "Property"), located in the State of Durango, Mexico.
Work on the Property by Focus included a review and re-evaluation of all previous data, surface sampling and diamond drilling. Focus had originally planned to carry out a 2,000 metre diamond drill program on the Property to test several targets, however party due to mechanical problems with the contracted drill equipment only approximately 500 metres in two holes were completed at the Estrella and Chicle zones. However, Focus' drilling did successfully encounter high-grade silver mineralization at depth in both holes. The most significant intersections found within the two holes were 2 metres of 305 g/t silver, which included 0.3 g/t gold from 239.6 metres down-hole at the Chicle Zone and 2 metres of 115 g/t silver from 188 metres down-hole at the Estrella Zone.
Focus' drill program was unable to test the Reventon Breccia Zone, where previous drilling by Northair in 2007 and 2008 returned significant intercepts of silver, zinc and lead within the majority of the completed holes, which included 155.4 metres of 71.3 g/t silver, 0.46% lead and 0.61% zinc from hole RC-08-08 and 22.9 metres of 287 g/t silver, 1.39% lead and 3.48% zinc from hole RC-08-13.
Northair now holds a 100% interest in the El Reventon silver-gold property, which consists of 3,370 hectares. The Property includes a 100% interest in the 60 hectare internal concession covering the Reventon Breccia, which was previously covered by an option agreement prior to Focus completing payments to the property owner as per the agreement with Northair. The El Reventon Property was acquired by Northair in 2006 and subsequent exploration by the Company identified numerous precious metal occurrences throughout the Property including the Reventon Breccia.
Northair appreciates the professional work that Focus completed on its El Reventon Project and will assess the results of their exploration program before deciding how to move the Property forward.
Sampling Quality Analysis and Quality Control
Core was first split in half using a diamond core splitter and then logged, and each box photographed prior to sampling. Half-core samples were bagged, security-sealed and transported by Inspectorate to their laboratories in Durango for preparation and shipping of pulps to Reno for analysis. Silver was determined by multi-acid digestion and ICP-AES, with fire assay gravimetric finish. Gold was assayed by Atomic Adsorption Spectrometry with fire assay gravimetric finish. Quality control by Oro Pacific involved the insertion of blind certified standards and blanks into the sample stream at regular intervals in order to independently assess analytical precision and accuracy of each batch of samples as they are received from the laboratory.
