GR Silver Mining Completes Sale of Non-Core Concessions
Vancouver, BC – GR Silver Mining Ltd. (“GR Silver Mining” or the “Company”) (TSXV|GRSL,
OTCQB|GRSLF, FRANKFURT|GPE) – announces the sale of two non-core concessions, El
Salto and El Salto Sur (the “Concessions”), which were acquired from Mako Mining Corp. on
March 31, 2021, to Grupo Minero Venturex S.A. DE C.V. (“Venturex”), a private Mexican
company.
The Concessions were sold to Venturex, in an ‘arm’s length’ transaction, with the following
terms and conditions:
• The Company received US$1,000;
• The Company was granted a 0.5% net smelter royalty (“NSR”);
• Venturex is responsible for complying with all obligations arising from ownership of the
Concessions in accordance with Mining Laws, Regulations, and the Federal Law of
Rights in Mexico; and
• Venturex is responsible for payment of all outstanding concession fees, fines,
surcharges and updates derived from the non-payment of mining fees of the
Concessions until the date on which the payments are made.
GR Silver Mining President and CEO, Marcio Fonseca, commented, “The sale of these two
Concessions is part of the Company’s strategy to divest non-core concessions acquired in
conjunction with the acquisition of the past producer La Trinidad mine. By selling these
Concessions, the Company will be eliminating the ongoing concession fee obligations and
current liability once approval of the sale is granted.”
El Salto and El Salto Sur represent extensive (combined area 569.1 sq. km) early-stage
exploration concessions to the southeast of the Plomosas Project, on the Sinaloa-Nayarit
border (Figure 1).
