Vancouver, British Columbia--(Newsfile Corp. - November 10, 2016) - RT Minerals Corp. (TSXV: RTM) (the "Company") reports on core drilling and new staking at its 100% owned Ballard Lake property located approximately 50 kilometres northeast of Wawa, Ontario.

Drill hole BA-16-01 intersected the Ballard Lake Shear Zone ("BLSZ") at 89 metres depth and returned anomalous gold values. Petrology of alkali ultramafic dikes also cut by drilling, show exotic mineralogy with compositions that suggest a deep crustal or mantle magma source.

The BLSZ may tap into deep crustal and mantle structures that could act as conduits for hydrothermal fluids and gold. The BLSZ and adjacent granodiorite/volcanic contact is a large surface structure, with ample room for significant mineralization. The Company has 12 kilometres of the Ballard Lake granodiorite-volcanic contact on its claims.

With potential for deep crustal or mantle tapping conduits, indicated by alkali ultramafic dikes and kimberlites in the area, the Company has staked 64 claim blocks at Ballard Lake to cover the contact and other exploration targets, increasing the property's size to approximately 160 square kilometres (~15,970 hectares). The new claims are subject to a 2% net smelter royalty, with 1% buyback for $1,000,000, as staking is contiguous and surrounds the original property.

RT Minerals Corp.'s Ballard Lake property now includes two historical diamond-bearing kimberlite occurrences: GC1 (16 diamonds from 93.1 kg), and Fletch (6 diamonds from 51.48 kg). Diamond results were reported by Chalice Diamond Corp. ("Chalice") in February 2008.

Chalice completed an exploration program in the Ballard Lake area that included regional kimberlite indicator mineral sampling, prospecting, modern airborne geophysical surveys, and ground geophysical surveys. No drilling was reported. RT Minerals will continue to evaluate these targets and will commence drilling on at least several of these targets in the coming weeks.

The Ballard Lake property lies in the Wawa supracrustal belt of the Superior Craton, which is currently being explored by major and junior exploration companies for both gold and diamonds.

Kevin Kivi, P.Geo., QP for the Company's Ballard Lake property, has explored for diamonds and gold in Canada since 1983, and approves the technical content of this press release.
