GoldMining Announces NI 43-101 Gold Resource for the Crucero Gold Project, Peru
January 16, 2018
- The Crucero NI 43-101 resource estimate includes an indicated resource of 1.0 Moz gold (30,653,000 tonnes at an average grade of 1.0 g/t gold) and an inferred resource of 1.1 Moz gold (35,779,000 tonnes at an average grade of 1.0 g/t gold) at a 0.4 g/t gold cut-off (See Tables 1 and 2 for details); and
- This resource estimate increases GoldMining's global measured and indicated resource to 9.5 Moz gold (12.4 Moz gold equivalent) and inferred resource to 11.7 Moz gold (14.2 Moz gold equivalent) across all of its projects resulting in a 13% increase in the indicated category and an 11% increase in the inferred category (see Table 4 for details).
Vancouver, British Columbia – January 16, 2018 – GoldMining Inc. (the "Company" or "GoldMining") (TSX-V: GOLD; OTCQX: GLDLF) is pleased to announce the results of a National Instrument 43-101 ("NI 43-101") mineral resource estimate for its Crucero Gold Project (the "Crucero Project" or the "Project") located in the Department of Puno, southeastern Peru. The estimate includes an indicated resource of 30,653,000 tonnes grading 1.0 g/t gold (1.0 Moz) and an inferred resource of 35,779,000 tonnes grading 1.0 g/t gold (1.1 Moz) at a 0.4 g/t gold cut-off.
Amir Adnani, Chairman of GoldMining, commented: "We are pleased to announce the resource estimate for our Crucero Project, which represents another milestone in the execution of our long-term growth strategy. In 2017, we worked towards furthering this strategy by successfully completing three acquisitions – the Crucero, La Mina and Yellowknife Gold Projects. Our plan in 2018 is to continue this strategy and build upon our vision of maximizing gold leverage for our shareholders."
Garnet Dawson, CEO of GoldMining, commented: "We are pleased to report this conceptual pit constrained resource estimate for the A1 deposit, one of several targets identified by geochemistry and geophysics on the Crucero Project by previous owners. Future exploration programs will look to expand the existing resource at the A1 deposit, test several of the nearby targets and complete additional metallurgical testwork."
The Crucero Project occurs within the Puno Orogenic Belt, which is host to orogenic gold deposits and associated extensive alluvial deposits in eastern Peru and Bolivia. The Project is road accessible by paved road from Juliaca to the town of Crucero, approximately 150 km to the northeast, with the remaining 50 km to the site by gravel road. High-power electrical lines pass within 8 km of the property.
The Project is comprised of three mining and five exploration concessions with an aggregate area of 4,600 hectares. The three mining concessions are held indirectly by a subsidiary of GoldMining through a 30-year assignment from a third party running until 2038 and are subject to certain net smelter return royalties of 1 to 5%, based on monthly gold prices.
The A1 deposit, as currently defined by trenching and drilling, strikes northwest and dips vertically to steeply to the northeast. The deposit is approximately 750 m long by 100 m in width and has been traced to a vertical depth of 400 m, but most of the drilling is confined to within 250 m of surface. The deposit is open at depth and along strike to the northwest and southeast. The structurally controlled gold mineralization is associated with sulphide veins hosted within strongly deformed metasedimentary rocks.
Historic exploration programs have focused on the A1 deposit, however geophysical and geochemical surveys have identified additional targets for follow-up exploration.
Crucero Resource Estimate
GoldMining engaged Global Mineral Resource Services to prepare an independent NI 43-101 technical report for the Crucero Project, including an updated pit constrained resource estimate for the A1 deposit. The indicated and inferred resource estimates, which have an effective date of December 20, 2017, are shown in Tables 1 and 2, respectively. Assumptions used for the pit modelling are shown in Table 3. A gold cut-off grade of 0.40 g/t was utilized based on similar types of mineralization found at other near surface deposits in the world and is highlighted in the tables below.

|Overall Pit Slope||47||Degrees|
The A1 deposit was modelled on a series of cross-sections and level plans from which a three-dimensional wireframe model was constructed for the mineralized zone at an approximate grade boundary of 0.1 g/t gold. Diamond drill holes (72) totaling approximately 23,000 metres and eleven trenches totaling approximately 3,285 metres were used to define the model (Figs. 1 and 2). High-grade gold values were capped at 17 g/t gold with 19 assays falling above this value. Assay sample lengths were composited at 2.5 metres within the domain. Variography was used to model the grade continuity and to determine the search ellipse orientations and dimensions for interpolation. Ordinary kriging was used to estimate gold into blocks measuring 10 x 10 x 10 metres in dimension. Average bulk density of 2.85 g/cm3 was used to convert block model volumes to tonnages.
Validation of the model was completed by comparison of the block model and drill hole grades by visual inspections in section and plan across the deposit.

Quality Control – Quality Assurance Program
The above resource estimate was based on drilling and trenching programs completed by previous operators. The drill programs incorporated control samples including blanks, duplicates and standards as part of their Quality Control – Quality Assurance Program. The control samples from the drill programs have been reviewed and verified by the Qualified Persons (as defined herein) and the assay results were deemed suitable for resource estimation. No information is available regarding the Quality Assurance – Quality Control Program from the trench sampling carried out between 1996 and 2003, however these samples represent only a small percentage (approx. 4%) of the overall assay database used in the resource estimate. The Qualified Persons (as defined herein) are of the opinion that the inclusion of these samples would not have a material effect on the reliability of the overall estimate.
The resource estimate disclosed herein on the Crucero Project was prepared for GoldMining by Mr. Greg Z. Mosher, B.Sc., M.Sc., P.Geo., of Global Mineral Resource Services (the "Qualified Person"). Mr. Mosher is recognized as a qualified person as defined in NI 43-101, is independent of the Company and has reviewed and approved the disclosure regarding the resource estimate for the Crucero Project disclosed herein.
A technical report respecting the above resource estimate will be filed under the Company's profile on SEDAR in due course. There is no new material scientific or technical information respecting the Crucero Project since the effective date of the resource estimate.
Paulo Pereira, President of GoldMining Inc. has reviewed and approved the technical information contained in this news release. Mr. Pereira holds a Bachelors degree in Geology from Universidade do Amazonas in Brazil, is a Qualified Person as defined in National Instrument 43-101 and is a member of the Association of Professional Geoscientists of Ontario.
Investors are cautioned not to assume that any part or all of the mineral deposits in the "measured", "indicated" and "inferred" categories will ever be converted into mineral reserves with demonstrated economic viability or that inferred mineral resources will be converted to the measured and/or indicated categories through further drilling. In addition, the estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of pre-feasibility or feasibility studies.
