GMV Engages Tetra Tech to Complete Updated Resource Estimate
Vancouver, British Columbia--(Newsfile Corp. - November 22, 2017) - GMV Minerals Inc. (TSXV: GMV) (the "Company" or
"GMV") is pleased to announce that the Winter 2016 and the Summer 2017 step out drill programs conducted on the Mexican Hat gold
property have concluded with 23 of 28 drill holes encountering gold mineralization above the previously established 0.2 gpt cut-off
that had been used for inclusion into a Mineral Resource.
This year's exploration has discovered new zones to the north and to the east of the previous reported NI 43-101 Mineral
Resource, adding 18.6 Hectares to the surface extent of the mineralization. Please see the attached link: https://www.gmvminerals.com/site/assets/files/1393/2017-gmv-mexican-hat-mineralization-expansion.jpg
Tetra Tech Inc. Completes Audit of 2015 Resource Estimate & Is Engaged
to Co-Author New Resource
At the recommendation of Dr. D.R. Webb, Ph.D., P.Geo., P.Eng., the Company's Acting Project Manager, GMV has engaged Tetra Tech
Inc. to co-author GMV's new resource estimate calculation and updated NI 43-101. Tetra Tech provides a full range of mining
services to the natural resource extraction industry, with 16,000 employees and a global presence. GMV is confident that the
investing community will recognize the Company's commitment to the highest standards of engineering and science through this
engagement.
The Company looks forward with positive anticipation as these drill intercepts and assays are incorporated into its upcoming
revised NI 43-101 resource. In keeping with GMV's management policy to double check data wherever financially prudent, earlier this
year Dr. Webb (QP) engaged Tetra Tech to audit methods, procedures and findings in conjunction with GMV's 2015 NI 43-101 filing on
its Mexican Hat Resource. The audit has now been completed, the methodology was reaffirmed, and a number of minor recommendations
to improve the resource outcomes were proposed.
Metallurgy
Metallurgical testing since 2016 has shown materially better gold recoveries than had been used in the previous resource
calculation. The introduction of the potential for run of mine (ROM) processing could mean a significant reduction in processing
costs. "Mr. John Fox, P. Eng., the Company's metallurgist previously reported in reference to testing completed in 2017, "these
results together with more comprehensive bottle roll testing have confirmed that no significant differences or issues exist from
all known mineralized rock-types from the property. This demonstrates substantial potential for a low-cost ROM or ROM plus
screening and single stage crush operation for the property. The results are materially better than average results for ROM
testing, when compared to currently operating open pit heap leach operations in the world, thus confirming that this low-cost
recovery method presents a viable option for the gold recovery of the deposit's lower-grade material."
Ian Klassen, GMV's President commented, "Even with an exceptionally aggressive drill step-out pattern the Mexican Hat deposit
remains open to the North, South and East, as well as to depth. Management believes that the previously calculated strip ratio of
1.5 to 1, used to establish cut-off grades for resource purposes could be improved with the inclusion of work completed over the
past year. The next few months will provide the data and guidance for the 2018 exploration plan. 2017 has been a very productive
year for the Mexican Hat Resource. We certainly look forward to the updated NI 43-101".
Shortly, the Company expects to receive results on three holes completed on a new gold zone, first identified by Placer Dome
(USA), located 2 km north of the Mexican Hat Mineral Resource. Once received, the Company will announce the results.
Dr. D.R. Webb, Ph.D., P.Geo., P.Eng. is the Q.P. for this release within the meaning of NI 43-101 and has reviewed the technical
content of this release and has approved its content.
