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

DENVER–(BUSINESS WIRE)–Solitario Zinc Corp. ((“Solitario”) NYSE American: XPL; TSX: SLR)
is pleased to announce that Nexa Resources (“Nexa”) (NYSE: NEXA; TSX:
NEXA) has begun the 2019 phase of the most aggressive surface drilling
program in the history of the Florida Canyon zinc project. Three core
rigs with helicopter support will be utilized for the 2019 program. The
Florida Canyon Project in northern Peru is held in a joint venture
between Solitario (39%) and Nexa (61%), the world’s fourth largest zinc
miner.

The 2019 program consists of drilling about 35 core holes totaling
approximately 15,000 meters (49,000 feet). Proposed drilling is designed
to test highly prospective resource expansion opportunities and is
focused on near-vertical zinc-lead replacement bodies and significant
gaps and offsets within nearly horizontal manto-style mineralization.
All targets are within and around the currently defined high-grade
zinc-sulfide resource. In addition to drilling, Nexa is funding a
significant road building program that will upgrade 31 kilometers of
previously constructed road, add another 10 kilometers that will
complete access to mineralized areas, and construct first-ever road
access to important community centers within the project area. Nexa is
the manager of the project.

Significant progress in interpreting Florida Canyon mineralization was
made in 2018 with the relogging of all previously drilled core totaling
117,000 meters in 487 core holes. An informative video found here
describes the conceptual drilling program and the local and
property-wide exploration potential.

Chris Herald, President and CEO of Solitario, commented, “This
aggressive and highly prospective drilling program has the potential to
increase the size of the deposit as well as enhance the confidence level
of the resource. We look forward to a steady stream of positive results
throughout much of 2019. This program is the culmination of an intensive
18-month effort to better understand the geometry of existing
mineralization and expand the potential scale of the project, which we
believe is significantly larger than is currently defined. We are
excited about the impact this drilling could have on project economics.
We are very pleased with the cooperation and support that the local
communities have confirmed with the signing of a new long-term community
agreement.”

Mr. Walt Hunt, COO for Solitario Zinc Corp., who is a qualified person
as defined by National Instrument 43-101, has reviewed the technical
information contained within this release.

Terms of the Florida Canyon Joint Venture

The Florida Canyon Project is held in a joint venture between Solitario
(39%) and Nexa Resources (61%) ((“Nexa”) NYSE: NEXA; TSX: NEXA), the
world’s fourth largest zinc miner. 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. To accelerate the development of the
Florida Canyon project, Solitario and Nexa have agreed to jointly fund,
30%-70% respectively, the cost for the 2018/2019 drilling program.
Funding that Solitario contributes towards this drilling program will be
fully credited towards repayment of the construction loan facility that
Nexa provides to Solitario for project construction.
