TORONTO, ONTARIO--(Marketwired - Jun 21, 2017) - Red Pine Exploration Inc. (TSX VENTURE:RPX) ("Red Pine" or the "Company") has received partial results for holes SD-17-75 to SD-17-78 (additional results pending) that were drilled between 150-200m south of the former Minto Mine (23,000 oz gold at 12.56/g/t)¹. Drilling results continue to demonstrate that the high-grade mineralization of the historic Minto Mine extends to the south. Furthermore, the mineralization of the Minto Mine South Zone appears to be hosted in stacked gold-bearing structures similar to the ones at the Surluga Deposit (>1M oz inferred gold resource at 1.71 g/t)².

Drilling highlights for the Minto Mine drilling program include (see Table 1 and Figures 1 and 2 below):

• Extension of the high-grade core of the Minto Mine South Zone intersected in SD-17-73;
  • SD-17-78 contains 11.82 g/t gold over 3.49m and 1.39 g/t gold over 0.91m in the Minto Mine South Zone;
    
    
• Indications that the Minto Mine South Zone remains open at depth and laterally;
  
  
• Confirmation of the continuity of the new discovery over its >1km length.

Quentin Yarie, President and Chief Executive Officer of Red Pine stated, "Our models of our Minto Mine South Zone discovery have been very robust. The structure is proving to be predictable and with drilling, we are able to trace this near-surface high-grade gold zone along strike and at depth. Our drilling results have also discovered additional mineralized structures in both the hanging wall and footwall of the Minto Mine South Zone, suggesting that not unlike the Surluga Deposit, we are looking at multiple stacked gold-bearing structures".

On-going Drill Program - Continued Expansion of the Minto Mine South Zone

Holes SD-17-82, SD-17-85, SD-17-86, SD-17-90 and SD-17-94 were drilled in the down-plunge continuity of the Minto Mine South Zone. They indicate that the gold-bearing quartz veins of the Minto Mine Structure thicken at depth with a considerable visible increase in sulphide content. Higher sulphide content has been associated with higher gold content (Assays pending).

Results for 13 boreholes covering an area of 250m x 120m drilled in the Minto Mine South Zone are still pending. The zone remains open at depth and along strike (>1km) to the south. Ten (10) additional drill holes are currently planned to further define its strike length and depth.

Wawa Gold Project

The Wawa Gold property package consists of over 5,500 hectares and hosts several former mines with a combined historic production of 120,000 oz gold¹. To date, the largest gold deposit on the property is the Surluga Deposit, which hosts a NI 43-101 Inferred Resource of 1,088,000 oz gold at an average grade of 1.71 g/t using a 0.5 g/t cut-off contained within 19.82 million tonnes².

Exploration work by Red Pine during the past 16 months has involved the ongoing sampling of 42,000 metres of historic core that was never sampled by previous operators of the project (initiated in February 2016) and aggressive drilling campaigns.

In March 2017, the Company completed a 6,000 metres of drilling and immediately initiated a new 10,000 metres drilling program. This was quickly expanded to 20,000 metres as a second drill was added to the campaign. The aggregate 20,000 metres drill program is designed to potentially expand the size of the existing inferred gold resource and connect other zones of gold mineralization (the Wawa Gold Corridor) recently discovered through drilling and other exploration techniques on the large Wawa Gold Project property.

The Company is well positioned to fund its share of the Wawa Gold exploration program. As such, the sampling and drill programs are expected to continue throughout 2017.

On-site Quality Assurance/Quality Control ("QA/QC") Measures

Drill core samples were transported in security-sealed bags for analyses to SGS in Lakefield, Ontario. Individual samples are labeled, placed in plastic sample bags and sealed. Groups of samples are then placed into durable rice bags and then shipped. The remaining coarse reject portions of the samples remain in storage if further work or verification is needed.

Red Pine has implemented a quality-control program to comply with best practices in the sampling and analysis of drill core. As part of its QA/QC program, Red Pine inserts external gold standards (low to high grade) and blanks every 20 samples in addition to random standards, blanks, and duplicates.
