Vancouver, BC, October 10, 2013.
Newport Exploration Ltd. ("Newport" or the "Company") is pleased to report a preliminary metallurgical testing program at the Chu Chua massive sulphide deposit, located near Barriere, British Columbia ("Chu Chua"). The program will be supervised by APEX Geoscience Ltd. ("APEX") of Edmonton, Alberta.
APEX will arrange for the transport of coarse reject sample material on hand from previous historic drill core re-sampling activities from APEX's Rock Creek warehouse facilities, where samples are currently being stored, to the ALS Metallurgy ("ALS") facilities in Kamloops, BC for further testing. Initial testing at ALS will include sample processing (crushing, grind calibration, head assays) and subsequent QEMSCAN PMA (particle mineral analysis) to determine the suitability of core from Chu Chua for further metallurgical (rougher and cleaner floatation) testing.
Initial QEMSCAN PMA testing has been planned to provide an indication as to whether further testing is likely to provide reliable information or alternatively if the sample material is too oxidized. Sample pH measured during grind calibration will also provide an indication of oxidation state of Chu Chua sulphide ores that may be sufficient to green-light additional testing. Initial rougher flotation tests include sample preparation, QEMSCAN PMA, 10 rougher flotation and 5 cleaner flotation tests.
This program should provide the metallurgical characteristics of the mineralization at Chu Chua, a massive sulphide deposit that with a base case cut-off threshold of 1.0% Cu, yields 2,506,000 tonnes at an average grade of 2.0% Cu, 0.3% Zn, 9.4 g/t Ag and 0.5 g/t Au (see News Release dated June 26, 2012). Chu Chua is considered to be prospective for development based on the project's favourable location for access, power, water, and labour.
Mr. Kristopher J. Raffle (P.Geo). and Steven J. Nicholls (M AIG) of APEX are the Independent Qualified Persons, as defined by NI 43-101, responsible for the mineral resource estimation. The resource is classified as an inferred mineral resource, consistent with the CIM definitions referred to in NI 43-101. The effective date of the mineral resource estimation is April 18, 2012. A total of 99 diamond drillholes, totaling 19,707 metres (m), ranging from AQ to NQ size core were completed between 1978 and 1991 to delineate the Chu Chua deposit. The mineral resource estimate is derived from a total of 50 of these drillholes; the spacing of which is between 10 and 40 m. A total of 251 composites of 5 m length, capped at 5.90% copper, 0.86% zinc, 32 g/t silver and 1.4 g/t gold, were used for the estimation.
Newport received TSX approval for the 100% acquisition interest Chu, subject to certain royalties, on October 3, 2013. (see News Release dated Oct. 3, 2013 filed on SEDAR).
