Test mining in three areas recovers 46% more tonnes with average mining width of 5.3 metres

VANCOUVER, British Columbia, Nov. 28, 2018 (GLOBE NEWSWIRE) — Pure Gold Mining Inc. (PGM – TSX-V) (“Pure Gold” or the “Company”) is pleased to report that test mining at Madsen has now completed with a total of 7,096 tonnes of mineralized material extracted from three distinct stoping areas. Test mining has been extremely successful in highlighting the strong visual nature of the mineralization, demonstrating excellent ground conditions, and confirming the geologic model that underpins the mine plan for the ongoing definitive feasibility study. Results have exceeded expectations, with tonnes, grade and mining width greater than predicted from the resource model. Overall, an average grade of 10.2 g/t gold was returned from 1,555 muck samples collected during mining of the bulk sample. The average grade of 10.2 g/t gold is a capped, diluted mined grade, which comprises all muck samples from 70 rounds of freshly blasted rock, each of which averaged above a cut-off of 4.0 g/t gold. 

Key points

• At a 4.0 g/t gold cut-off, the bulk sample estimate includes 46% more tonnes, 8% higher gold grade and an estimated 56% more ounces of gold than predicted from the resource model blocks;
• Overall mining width of 5.3 metres, exceeding the predicted width of the mineralized structures by 53%.
• In the two planned stoping areas, mined tonnes were within 1% of the predicted tonnes from the resource model, with an estimate of 14% more ounces than expected due to a higher than predicted average diluted grade of 10.9 g/t gold at a 4.0 g/t gold cut-off;
• Underground drilling conducted during test mining defined a third stoping area, resulting in the mining of an estimated 440 additional ounces of gold from 1,575 tonnes at a grade of 8.7 g/t gold;
• Further underground drill results continue to identity opportunities for extensions to mining. New drilling highlights include:
  – 20.1 g/t gold over 6.0 metres from drill hole PGB-0131, including 38.6 g/t gold over 2.0 metres;
  – 47.6 g/t gold over 6.0 metres from drill hole PGB-0134;
  – 30.3 g/t gold over 2.0 metres and 133.0 g/t gold over 1.0 metre from drill hole PGB-0140;
  – 15.2 g/t gold over 2.9 metres from drill hole PGB-0152.

Darin Labrenz, President and CEO of Pure Gold commented, “Our test mining program has been a resounding success, checking each of the boxes we laid out when we initiated the program earlier this year. From the first round blasted in the ramp to the completion of the program in November, our team has demonstrated it can visually identify, and easily follow gold mineralization underground providing a strong validation of our geologic model. Overall, test mining returned an estimated 56% more gold than predicted, with limited dilution achieved through average widths that exceed five metres. With test mining now complete, delivering a strong validation of both geologic model and resource, we look forward to finalizing our definitive feasibility study as the next step to building a modern, scalable mining operation at Madsen.”

Pure Gold Completes 7,100 tonne Bulk Sample

In late May, the Company initiated a bulk sample program designed to partially test two proposed stopes from the McVeigh zone. Test mining was completed in excellent ground conditions with approximately 242 metres of new lateral drive development completed near the base of the two proposed stopes at a depth of approximately 160 metres below surface, and the completion of 24 metres of vertical development in two raises. An important outcome of the test mining program was the recognition of the strong visual nature of the mineralization, including abundant visible gold, distinctive veining and alteration typical of the Red Lake mining district, allowing the team to efficiently mine higher grade mineralization with limited dilution.

Grade reconciliation reported is defined by muck samples collected in a regular pattern with five individual muck samples, averaging 2 kg each, taken from every second scoop bucket, resulting in one muck sample for every three tonnes of mining. Typically, each blast had an average of about 25 muck samples collected, and all the samples from each round were averaged to confirm a particular rounds grade exceeded the 4.0 g/t gold cut-off. The average mining width over a total of 70 mining faces is 5.3 metres, with a maximum of twelve metres in true width, resulting in lower mining dilution and suggesting an opportunity locally for increased utilization of efficient bulk mining methods. 

Reconciliation between mined material and the mineral resource from the two proposed stopes was exceptionally strong, with actual tonnes equal to the predicted total at a 4.0 g/t gold cut-off, and actual grade exceeding predicted by 15%. When compared to initial, diluted stope designs for the two stoping areas, test mining achieved a 20% higher grade and 11% more ounces than predicted. Overall, test mining returned 56% more gold than predicted from the resource due to the mining of parallel structures in a third stoping area, discovered by close spaced drilling conducted from underground. The successful mining of these parallel structures highlights an opportunity for future growth and additional mining from delineation drilling from underground. A summary of the test mining is outlined in the Tables reported below.

Mineralized material from the bulk sample has been stockpiled in a secure underground location at Madsen and is expected to provide future feed for mill commissioning.

Phil Smerchanski, Vice President, Exploration of Pure Gold added, “The positive results of this mining highlight the disciplined and conservative approach that Pure Gold has applied to resource estimation. Our resource work is well supported by comparison to this test program and also the extensive previous mining records at Madsen. It has been invigorating to get to work mapping and mining this gold mineralized rock that we have focused so much study on over the last 4 years. Our whole team is very excited about the growth possibilities at Madsen.”

Underground Drilling

In concert with an extensive sampling program to characterize the mineralization during test mining, the drift walls were tested each round with a core drill to identify potential for additional mineralization. EW-sized (2.5cm) core drill holes were drilled with a Bazooka air drill with holes averaging 13 metres in length. This underground drill program has been highly successful, identifying additional mineralized structures outside of, but in close proximity to new mine development. Three of these tested structures have been partly mined along with the current bulk sample. Many of the structures remain open and demonstrate continuity providing opportunities to be incorporated into a future mine plan following a positive production decision. A summary of the new drill results is outlined in the table reported below.

QA/QC and Core Sampling Protocols
All underground samples and drill core samples are bagged and sealed and submitted to SGS in Red Lake, Ontario for sample preparation by crushing to 75% less than 2mm, a riffle split of 1kg, and pulverization of the split to better than 85% passing 75 microns. Gold analysis is completed in the SGS Red Lake lab with a 30g fire assay and AAS finish (code GO-FAA303). Samples returning >100 g/t Au are re-assayed with a gravimetric finish (code GO-FAG303). Control samples (accredited standards, duplicates, and non-accredited blanks) were inserted on a regular basis. Results are assessed for accuracy, precision and contamination on an ongoing basis.
