Comstock Metals Ltd. (TSX-V:CSL) and Select Sands Corp. (TSX-V:SNS) are pleased to announce that they have entered into a definitive agreement setting forth the terms under which Comstock will purchase Select Sands’ Preview SW gold project located in the La Ronge district of Saskatchewan and Select Sands’ early-stage Old Cabin property in Ontario each as previously disclosed in the press release dated May 16, 2016. Under the terms of the Agreement Comstock will acquire the Assets for 20 million common shares in the capital of Comstock and the assumption of certain liabilities associated with the Assets.

Preview SW Gold Project

The Preview SW gold project is located 40 km north of La Ronge, Saskatchewan and 80 km southwest of Silver Standard Resources Inc.’s Seabee gold mine. The Preview SW project database contains results from 162 core holes, totaling 26,250 m, drilled between 1985 and 2013. Of these, 136 were drilled on the main Preview SW deposit and form the basis for a NI 43-101 Resource Estimate¹ (see Select Sands’ October 1, 2013 News Release) that included:

• Indicated resources containing 158,300 ounces of gold (2.61 million tonnes grading 1.89 g/t Au) based on a 0.50 g/t Au cut-off grade.
• Inferred resources containing 270,800 ounces of gold (5.70 million tonnes grading 1.48 g/t Au) based on a 0.50 g/t Au cut-off grade.

The main Preview SW deposit is comprised of several sub-parallel northeast-trending gold-bearing quartz-sulphide mineralized structural zones, 500 m in strike length and totalling 150 m in width. Preliminary metallurgical test work indicates total gold recovery in concentrates ranged from 90% to 93%

In addition, there are six additional known gold zones on the 853 ha property with only limited drilling. At the Preview North zone, located 2.6 km northeast of the Preview SW deposit, drill hole PR13-163 intersected:

• 17.98 g/t Au over 5.71 m starting at 10 m below surface;
• 5.96 g/t Au over 5.66 m starting at 19 m below surface; and,
• 1.88 g/t Au over 21.26 m starting at 29 m below surface

There has been insufficient drilling at the Preview North zone to determine the attitude of the reported mineralized intervals and, therefore, the above mineralized intersections may not represent true widths. No drilling has been carried out for over 600 m to the south of this hole.

The Company confirms that it will file a technical report on the Preview SW Gold Property within 180 days of this press release to support the above disclosed SW deposit mineral resource estimate.

Old Cabin Project

The 1,118 ha Old Cabin project is located 80 km northeast of Wawa, Ontario and 10 km east of Richmont Mines’ Island Gold Mine, which is forecast to produce 62-67,000 oz of gold in 2016². It should be noted that the mineralization hosted on the Richmont Property is not necessarily similar to the mineralization hosted on the Old Cabin Property. The property has had surface sampling and geological mapping carried out, resulting in the discovery of 13 discrete gold zones, all associated with shear zones and strong iron carbonate alteration. Highlights of results reported by Select Sands include a channel sample of 40.5 g/t Au over 1.68 m.

The completion of the transaction is subject to a number of conditions including receipt of all necessary regulatory approvals (including the approval of the TSX Venture Exchange).

Given that Comstock and Select Sands have certain directors that serve as directors of both Comstock and Select Sands, each board appointed independent committees to review the proposed transaction. Furthermore each committee received independent fairness opinions confirming that the transaction is fair from a financial perspective to the shareholders of each of Comstock and Select Sands.

As noted above this transaction remains subject to a number of conditions and there can be no assurances that the proposed transaction will be completed as proposed or at all.

Further details regarding the Preview SW gold project can be found in Select Sands’ press releases dated May 16, 2016 and March 17, 2016.

About Comstock Metals Ltd.

Comstock Metals Ltd. is a mineral exploration company. Its flagship 16,335 hectare QV Property is located in the White Gold district of the Yukon Territory, approximately 70 kilometres south of Dawson City and 44 kilometres northeast of the Coffee project of Goldcorp Inc., which it recently acquired through an acquisition of Kaminak Gold Corporation through a court approved plan of arrangement in a deal valued at C$520 million at the time it was announced. To date, the Company has completed 3,400 metres of drilling in 17 drill holes which formed the basis for a maiden Inferred mineral resource totalling 4.4 million tonnes grading 1.65 g/t gold containing 230,000 ounces of gold at a 0.5 g/t gold cut-off (See Comstock July 8, 2014 News Release). The VG Deposit remains open in all directions and is proximal to other untested sub-parallel structures. The VG Zone has similar geology and style of mineralization to Kinross’s Golden Saddle deposit, located 11 kilometres to the south. Additional promising targets exist on the QV Project, with potential for the discovery of significant intrusion related and/or orogenic gold mineralization. The infrastructure associated with the development of the Coffee project, including upgrading and completion of the mine access road, will benefit all projects in the district, including the QV Property.

Comstock also owns early stage uranium claims in the Patterson Lake area of Saskatchewan and has optioned out its Corona property in Mexico

About Select Sands Corp.

Select Sands’ Sandtown property, located in northeast Arkansas, USA, is underlain by the Ordovician St. Peter sandstone formation, which is a major source of ‘Ottawa White’ Tier-1 frac sand/industrial sand selling into major US oil and gas basins as well as industrial and speciality end markets. The Sandtown property is located 3.1 miles from Highway 167 near a natural gas pipeline. The property has an active power line on the property and is located approximately 14.7 miles from the nearest rail system (see Select Sands December 4, 2014 News Release). Compared to competitive sand mines located in Wisconsin owned by the largest US frac sand producers, Sandtown has a competitive location advantage as it is approximately 650 rail miles closer to the Texas/Louisiana oil/gas plays as well as the Houston port and industrial hub.

As per the June 2015 Preliminary Economic Assessment report by Tetra Tech of Golden, Colorado, USA and Vancouver, BC, Canada, the Sandtown property has a pre-tax NPV valued at US $160 million and a post-tax NPV valued at US $92 million. The PEA was completed on a portion of the current silica sand mineral resources (see the Select Sands’ June 10, 2015 news release). Select Sands would like to remind investors that mineral resources for the Sandtown Property are not mineral reserves and do not have demonstrated economic viability and there is no certainty that this PEA will be realized. Subsequent to the completion of the 2015 PEA, Select Sands announced an updated mineral resource estimate for the Sandtown property totaling 41.98 Million Tons of Indicated Silica Sand Resources.
