Pure Gold Mining Inc. ("Pure Gold" or the "Company") is pleased to announce additional drill results from the ongoing 51,000 metre drill program at the Company's 100% owned Madsen Gold Project ("Madsen"). Results reported herein are from the four drill rig exploration program, designed to expand the high grade gold resource in close proximity to the existing permitted infrastructure.
Highlights from new drilling include:
- 61.0 g/t gold over 1.4 metres in hole PG16-151 (Austin)
- 32.5 g/t gold over 2.0 metres in hole PG16-152 (McVeigh)
- 50.2 g/t gold over 4.0 metres in hole PG16-154 (McVeigh)
- Including 185.0 g/t gold over 1.0 metre
- 67.5 g/t gold over 1.1 metres in hole PG16-167 (McVeigh)
"We are aggressively drilling to add to the existing resource of 928,000 ounces Indicated (3.24 million tonnes at 8.93 g/t gold) and 297,000 ounces Inferred (0.79 million tonnes at 11.74 g/t gold), which currently represents one of the highest grade undeveloped gold resources of scale in Canada," said Darin Labrenz, President and CEO of Pure Gold. "Importantly we are adding confidence and continuity to underground, ramp accessible gold which has the potential to expand on the mine plan outlined in our recently completed PEA1. The McVeigh horizon is open in all directions, with three drill rigs systematically stepping along strike and down dip to delineate the size potential. We now have intercepts into the McVeigh horizon from surface down to 370 vertical metres, with the zone demonstrating positive down plunge continuity. Drilling to date has outlined significant growth potential at Madsen, with the opportunity to add to an already well-endowed mine complex."
Building Continuity Below Mine Workings
Gold mineralization in the McVeigh horizon has been intersected over a one kilometre strike length, to a depth of 370 metres below surface, and remains open. Current drilling indicates that high grade shoots intersected at the McVeigh have similar geometry and style to the Austin horizon mineralization which occurs in the hanging wall, and from which over two million ounces was historically mined.
New drill holes anchor a gold zone that extends well beyond any shallow historical workings (see McVeigh West long section). This mineralization lies largely outside of proposed mining shapes defined in the PEA, thus showing potential to positively impact the mineral resources in this area, and in any future production scenarios1. Additionally, holes currently in progress have encountered strong alteration, silicification and mineralization in 100 metre and 200 metre step-outs from results reported herein, and are interpreted to be further extensions of the McVeigh horizon. Furthermore, drilling by previous operators has demonstrated the depth potential of the McVeigh mineralization to a vertical depth of one kilometer. These results include 61.9 g/t gold over 0.7 metres (MUG-11-17) at 980 metres depth and 17.7 g/t gold over 2.0 metres (MUG-12-29) at 1,060 metres depth1.
Drill Results Summary
New assay results from select drill holes are outlined below:
*Assay composites were calculated using uncut assays and are reported as drilled widths and interpreted to vary between 50% to 90% of true widths.
The results of Pure Gold's ongoing $9.1 million drill program continue to reinforce that the McVeigh horizon is a folded footwall continuation of the Austin horizon, is open in all directions, and remains largely untested. While the Austin horizon, which is situated 150 metres in the hanging wall of the McVeigh horizon, produced over two million ounces from surface to a depth of 1.2 kilometres, the McVeigh was only mined to a maximum depth of 230 metres. Pure Gold's work to date has identified significant endowment potential in the McVeigh horizon, with gold bearing intersections present from surface to over a kilometre vertical depth.

Pure Gold's 2016 exploration program is on-going with three drill rigs currently testing the McVeigh horizon and a fourth drill rig testing satellite targets, including Russet South. The program is expected to include 51,000 metres of core drilling, of which 32,532 metres have been completed and released to date. Further results will be released as available.
The Madsen Mine operated for over 36 years with historic production of 2.5 million ounces at an average grade of 9.9 g/t gold. The Madsen Gold Project hosts a permitted mill and tailings facility, and access to power, water and labour. The Madsen Gold Project has an Indicated Resource of 928,000 ounces gold at 8.93 g/t gold (in 3.24 million tonnes) and an Inferred Resource of 297,000 ounces gold at 11.74 g/t gold (in 0.79 million tonnes)1. The mineral resource is based on 13,624 drill holes, evenly dispersed throughout the mineral resource. A robust geologic model based on 27 levels of geological mapping and chip sampling provides a solid understanding of the geology and continuity of mineralization.
In addition to the mineral resource, the Madsen Gold Project hosts a number of prospective new discoveries including the Fork Zone and Russet South targets, as well as, two significant historic underground mines. Pure Gold believes the opportunity exists to advance these targets through the application of modern exploration science and a new understanding of the district.

QA/QC and Core Sampling Protocols
Drill core samples are submitted to ALS Minerals in Thunder Bay, Ontario for sample preparation by crushing to 70% less than 2mm, a rotary split of 1kg, and pulverization of the split to better than 85% passing 75 microns. Sample pulps are shipped to the ALS assay laboratory in North Vancouver, B.C. for gold analysis with a 30g fire assay and AAS finish (code Au-AA23). Samples returning >5 g/t Au are re-assayed with a gravimetric finish (code GRA21). Mineralized zones with visible gold are also analyzed by a 1kg screen fire assay with screening to 100 microns. A duplicate 30g fire assay is conducted on the screen undersize with assaying of the entire oversize fraction (code Au-SCR21). Control samples (accredited standards and non-accredited blanks) were inserted on a regular basis. Results are assessed for precision on an ongoing basis.
