Solitario Announces Major Drilling Program on Its Florida Canyon Zinc Project, Peru

DENVER--(BUSINESS WIRE)--Solitario Zinc Corp. ((“Solitario”) NYSE American: XPL; TSX: SLR) is pleased to announce that a significant drilling program for the Florida Canyon zinc project is scheduled to begin in the third-quarter of 2018, pending drilling permit approvals. Forty-one core holes totaling approximately 17,000 meters (56,000 feet) are planned. Florida Canyon (formerly called the Bongará Project) is held in a joint venture between Solitario and Nexa Resources ((“Nexa”) NYSE: NEXA; TSX: NEXA), the world’s fourth largest zinc miner. Nexa is the manager of the project.

The drilling program has been designed to test highly prospective resource expansion opportunities identified by deposit modeling during preparation of the 2017 Florida Canyon PEA. Proposed drilling is focused on significant gaps and offsets in known high-grade zinc-sulfide mineralization within and contiguous with the presently defined resource.

An informative video found here describes in detail the drilling program and exploration potential within and surrounding the Florida Canyon deposit.

Drilling will test for extensions of high-grade zinc-sulfide mineralization in four different areas of the deposit. (Map link to North Areas) (Map link to San Jorge)

Area	Planned Holes	Total Meterage	Avg. Hole Depth (m)	Comments
North Central	6	2,695	449	connecting sulfide mantos* with good continuity
Northeast	17	7,805	459	east and northeast extensions of high-grade Karen-Milagros sulfide mantos
Northwest	7	1,700	244	northerly extension of sulfide mantos and delineation of a vertical feeder structure
San Jorge	11	5,060	458	southern extension of main feeder structure, adjacent sulfide mantos and parallel veins
Total	41	17,260	402
*Mantos are lenses of massive mineralization that replaces stratigraphic rock formations.

Chris Herald, President and CEO of Solitario, commented, “The second half of 2018 will be exciting times for Solitario and its shareholders. The objective of this drilling campaign is to add another 800 million pounds of zinc metal to the Florida Canyon resource base. Every drill hole is designed to intersect high probability extensions to known high-grade zinc mineralization. We are excited about the impact this drilling could have on project economics.” For comparison purposes, Table Two below provides highlights of the last Florida Canyon drilling program completed in 2013 and serves to illustrate the high grade and thickness of Florida Canyon mineralization.

* True thicknesses have not been estimated for each individual intercept, but are generally thought to average about 70-80% of the actual drilled thicknesses.

Mr. Walt Hunt, COO for Solitario Exploration & Royalty Corp., who is a qualified person as defined by National Instrument 43-101, has reviewed the drill hole information contained within this release. Samples are derived from 50% splits of HQ and NQ (2.5 and 1.9 inch) diameter core. Samples are then shipped via secured third-party land and air transportation companies and analyzed by ALS Chemex Inc., North Vancouver, Canada, an ISO9002 registered company.

Terms of the Florida Canyon Joint Venture and Funding of the 2018/2019 Drilling Program

Solitario and Nexa have agreed to jointly fund the estimated $5.3 million total cost for the 2018/2019 drilling program with Nexa contributing 70% and Solitario funding 30%. Funding that Solitario contributes towards the 2018 drilling program will be fully credited towards repayment to Nexa of the construction loan facility it provides to Solitario (see below).

Solitario owns a 39% interest and Nexa owns a 61% indirect interest in the Florida Canyon project. Nexa can earn a 70% interest in the Florida Canyon project by continuing to fund all project expenditures and committing to place the project into production based upon a positive feasibility study. After earning 70%, and at the request of Solitario, Nexa has further agreed to finance Solitario’s 30% participating interest for construction through a project loan. Solitario will repay the loan facility through 50% of its net cash flow distributions from production.
