(TSXV: BHT) (\"Braveheart\" or, the \"Company\") Mr. Ian Berzins, CEO, Braveheart Resources Inc. reports:Braveheart has released positive mineralized material sorting test results from quartz bearing vein material at the Alpine Mine gold project near Nelson, British Columbia. Testing was carried out by STEINERT US INC. (STEINERT) at their facilities in Walton, Kentucky using their multisensory sorting system (KSS). Aaron Matlock, Braveheart's Chief Operating Officer, was in attendance during the test. Samples tested included 72 kg of run of mine (ROM) material and 128 kg of a composite sample for a total of 200 kg. Samples were shipped to SGS Laboratories, an ISO 17025 accredited laboratory in Lakefield, Ontario for preparation and analysis.The purpose of the testing was to determine whether the STEINERT ore sorting system and methodology can be used to up-grade mineralized material originating from the Alpine Mine project prior to trucking and processing. The STEINERT machine incorporates a combination of X-ray transmission sensors (XRT) and laser sensor technology. The X-ray transmission targets the atomic density of the material and measures the X-ray attenuation of each particle which has a direct correlation on the mineral composition of the rock. This allows higher density material to be separated from lower density material. The former contains more of the mineralized rock and the latter is separated as low-grade or waste. The laser sensor targets the shape and brightness of a particle.In preparation for testing of the ROM and composite samples the -10mm fines were removed by screening. The ROM and composite test samples ranged in size from -50mm to +10mm in size. During testing the ROM material was up-graded from a feed grade of 14.7 g/t Au to 20.3 g/t Au with 92.8% gold recovery and 32.7% waste rejection. The composite material was up-graded from a feed grade of 25.4 g/t Au to 43.2 g/t Au with 81.3% recovery and 52.1% waste rejection.Ian Berzins, Braveheart's Chief Executive Officer, commented: \"The test results are very encouraging and indicative that STEINERT sorting of mineralized material at the Alpine Mine could be an important ...
