HALIFAX, NS, July 29, 2020 /CNW/ - GoGold Resources Inc. (TSX: GGD) (OTCQX: GLGDF) ("GoGold", "the Company") is pleased to announce their Initial Mineral Resource Estimate for their Los Ricos South Project located in Jalisco State, Mexico. In addition, the Company has updated the Mineral Reserve at the Parral Tailings operation, and the Mineral Resource Estimate at its Esmerelda Tailings Project located near Parral.

Highlights of the Mineral Resource Estimate and Mineral Reserve:

Measured & Indicated Mineral Resource at Los Ricos South of 63.7 million ounces silver equivalent ("AgEq") grading 199 g/t AgEq contained in 10.0 million tonnes ("Mt")
Inferred Resource at Los Ricos South of 19.9 million ounces AgEq grading 190 g/t AgEq contained in 3.3 Mt
Total Company Measured & Indicated Mineral Resources of 108.6 million ounces AgEq
Proven & Probable Mineral Reserve at Parral of 31.6 million ounces AgEq grading 64 g/t AgEq contained in 15.4 Mt
Measured & Indicated Mineral Resource at Esmerelda of 13.3 million ounces AgEq grading 72 g/t AgEq contained in 5.7 Mt
Los Ricos South Mineral Resource is amenable to both open pit and bulk underground mining methods
Los Ricos South Mineral Resource Estimate will form the basis of a Preliminary Economic Assessment ("PEA") expected to be completed by the end of 2020
Inferred out of pit grades range from 355 g/t AgEq to 512 at higher cut-off rates, as per Table 3.

"This initial Mineral Resource Estimate demonstrates Los Ricos South is a premium asset, in grade and quantity of ounces. Our Mineral Reserve at Parral is generating cash flows that are being reinvested into the Los Ricos district. Over the past 16 months, we have aggressively explored and developed the Los Ricos South Mineral Resource, which we will base our PEA study upon. Concurrently, we are accelerating our exploration effort on the Los Ricos North project where we are drilling the first of multiple targets which we believe will highlight the potential of the entire Los Ricos district," said Brad Langille, President and CEO. "Drilling is still underway at Los Ricos South targeting the northern extensions and extensions at depth."

The effective date of these Mineral Resource and Mineral Reserve Estimates is July 28, 2020 and a Technical Report on Los Ricos will be filed on the Company's website and SEDAR within 45 days of this news release. The pit constrained and out-of-pit Mineral Resources for Los Ricos South are summarized below in Table 1, and cut-off sensitivities are provided in Tables 2 and 3. The Updated Parral Mineral Reserve is summarized below in Table 4. The Updated Esmerelda Mineral Resource is summarized below in Table 5. Table 6 summarizes the Company's total Mineral Resources.

1.	Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
2.	The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
3.	The Mineral Resources in this news release were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
4.	Historically mined areas were depleted from the Mineral Resource model.
5.	The pit constrained AuEq cut-off grade of 0.43 g/t Au was derived from US$1,400/oz Au price, US$16/oz Ag price, 93% process recovery, US$18/tonne process and G&A cost. The constraining pit optimization parameters were $2.00/t mineralized mining cost, 1.50/t waste mining cost and 50-degree pit slopes.
6.	The out-of-pit AuEq cut-off grade of 1.4 g/t Au was derived from US$1,400/oz Au price, US$16/oz Ag price, 93% process recovery, $40/t mining cost, US$18/tonne process and G&A cost. The out-of-pit Mineral Resource grade blocks were quantified above the 1.4 g/t AuEq cut-off, below the constraining pit shell and within the constraining mineralized wireframes. Out–of-Pit Mineral Resources are restricted to the Los Ricos and Rascadero Veins, which exhibit historical continuity and reasonable potential for extraction by cut and fill and longhole mining methods.
7.	No out-of-pit Mineral Resources are categorized as Measured.
8.	AgEq and AuEq calculated at an Ag/Au ratio of 87.5:1.

Mineral Resource Estimate Methodology – Los Ricos South
A total of 286 drill holes totalling 39,409 metres were used in the Mineral Resource Estimate. The nearest neighbour mean distance between drill hole collars is 24 m.

P&E Mining Consultants Inc. ("P&E") collaborated with GoGold personnel to develop the mineralization models, estimates, and reporting criteria for the Mineral Resources at Los Ricos. Mineralization models were initially developed by GoGold and were reviewed and modified by P&E. A total of five individual mineralized domains have been identified through drilling and surface sampling. The modeled mineralization domains are constrained by individual wireframes based on a 0.40 g/t AuEq cut-off. The average true thickness of the modeled Los Ricos Domain is 15.3 m. The average true thickness of the modeled Rascadero Domain is 11.5 m.

Mineralization wireframes were used as hard boundaries for the purposes of estimation.

A 5m x 5m x 5m three-dimensional block model was used for the Mineral Resource Estimate. The block model consists of estimated Au and Ag grades, estimated bulk density, classification criteria, and a block volume inclusion percent factor. Au equivalent block grades were subsequently calculated from the estimated Au and Ag grades.

Sample assays were composited to 1m standard length composites. Au and Ag grades were estimated using Inverse Distance Cubed weighting of between 4 and 12 composites, with a maximum of 3 composites per drill hole. Composites were capped prior to estimation by mineralization domain. Composite samples were selected within an anisotropic search ellipse oriented down the plunge of identified high grade trends.

A bulk density model was estimated from 592 measurements taken from drill hole core using Inverse Distance Squared weighting.

Classification criteria were determined from observed grade and geological continuity as well as variography. Measured Mineral Resources are informed by 4 or more drill holes within 30 m; Indicated Mineral Resources are informed by 3 or more drill holes within 60 m.

P&E is of the opinion that the Mineral Resource Estimates are suitable for public reporting and are a reasonable representation of the mineralization and metal content of the Los Ricos Deposits.

Parral & Esmerelda
In addition to announcing the Initial Mineral Resource Estimate at Los Ricos South, the Proven & Probable Mineral Reserve at Parral was updated to reflect the mining of material since the Project's inception, as well as for updated gold and silver pricing consistent with that of Los Ricos South's. The Updated Mineral Reserve at Parral resulted in a positive reconciliation of 14% on tonnage and 27% on AgEq ounces.

The Mineral Resource Estimate for the Esmerelda Project was updated as well based on the updated metal pricing, which resulted in an increase of 6% on AgEq ounces.
