GoldMining Reports New Drill Results Highlighting Exploration Potential at São Jorge Project, Pará State, Brazil

VANCOUVER, BC, Jan. 6, 2026 /CNW/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX: GOLD) (NYSE American: GLDG) is pleased to report additional assay results from the 2025 RC drilling program at its 100% owned São Jorge Project ("São Jorge" or the "Project") in the Tapajós gold district ("Tapajós"), Pará State, Brazil. New exploration results further support the initial drilling results that identified exploration discoveries at four new gold prospects, including at the William South prospect located approximately 1.5 kilometre ("km") north of the existing São Jorge deposit (the "Deposit") (see news release October 20, 2025). 

The reverse circulation ("RC") drilling results detailed in this release comprise the continuation of the William South drilling program ("the Program"), a high priority part of the broader 2025 São Jorge Project exploration program which the Company designed to test new targets outside of the known areas of mineralization.

Highlights:

• William South RC Drilling Results:
  • 12 metres ("m") at 2.38 grams per tonne ("g/t") gold ("Au") from 13 m depth, including 1 m at 22 g/t Au (SJRC-048-25)
  • 4 m at 1.11 g/t Au from 46 m depth (SJRC-049-25)
  • 1 m at 1.23 g/t Au from 16 m depth (SJRC-047-25)
• Preliminary processing of Induced Polarisation ("IP") data indicates drilling completed at William South to date has only tested the southern flank of a broad chargeability anomaly, which is similar in scale and intensity to the known IP signature of the São Jorge Deposit.
  • Drilling over the highest chargeability core of the William South IP anomaly is planned in 2026.
• A total of 9,533 metres of drilling was safely and successfully completed on-budget during 2025.
• Exploration results received to date support the broader potential for discovery and delineation of new zones of mineralization across the 46,000 hectare São Jorge Project.

Alastair Still, Chief Executive Officer of GoldMining, commented: "GoldMining is further encouraged by the additional positive drill results yielded from the 2025 RC drilling completed to date at the William South prospect, an emerging gold discovery located a short distance from the known São Jorge gold deposit. The geology and geophysical signature at William South resembles the São Jorge gold deposit itself based on exploration to date. This work has been encouraging of the potential for this area, highlighting that significant additional systematic exploration is required, especially over the core of the IP anomaly which has not yet been tested by drilling.

In conjunction with William South, we continue to explore additional targets across the broad 12 km x 7 km geochemical footprint overlying the São Jorge property-scale mineral system, where we have additional exploration results pending. The excellent infrastructure at the 100% owned 46,000 hectare São Jorge Project includes easy access to paved highway, grid power and an existing 50-person camp that has facilitated our exploration activities to date as we continue to systematically explore this highly prospective regional-scale property in the rapidly emerging Tapajós gold district."

Project Overview

The São Jorge Gold Project is located in the Tapajós gold district (see Figure 1) in the south-central portion of the Amazon Craton. The São Jorge gold deposit is a granite-hosted, intrusion-related gold deposit which is a similar deposit style to the Tocantinzinho gold mine located approximately 80 km northwest of São Jorge. Exploration activities at the Project carried out by the Company over the past two years have successfully delineated several new exploration targets comprising gold ± copper ± molybdenum ± silver soil geochemical anomalies, which cumulatively outlines a large mineral system (see news releases dated March 18 and April 14, 2025).

2025 São Jorge Mineral System Exploration Program

The São Jorge mineral system is defined by a comprehensive exploration data set which the Company has developed over previous campaigns. Surrounding the previously delineated São Jorge deposit, which has a defined 1.4 km strike length, the broader mineral system comprises a zone of contiguous surface geochemical anomalies over an area of 12 km x 7 km, which the Company interprets to be the surface expression of a broad intrusive related gold system.

The 2025 São Jorge exploration program successfully and safely completed a total of 9,533 m of drilling, which exceeded the total planned meterage of 9,000 m while remaining on–budget. The Project benefitted from the introduction of RC drilling which is cheaper and more rapid than diamond core, while providing greater depth penetration and assay reliability than auger drilling. The Program comprised 3,862 m diamond core, 3,528 m RC and 2,143 m auger drilling.

Of the 84 RC holes drilled to date across the Project for a total of 3,528 metres, assays have been returned for 78 holes, with the remaining 18 holes pending assays. To date, four target areas have returned >1 g/t Au intercepts from RC drilling: William South, William North, Ivonette and Dragon West (see Figure 2).

Previously announced initial intercepts at the William South prospect included 4 m at 1.78 g/t Au from 12 m depth (see news release October 20, 2025).

New assay results are presented herein for additional drilling at the William South Prospect, which is located 1.5 km north of the Deposit. The full drilling program at William South comprised 20 RC holes drilled on three fences to test beneath a broad zone of elevated gold-in-soil and auger drilling geochemistry. The western–most drill fence returned the best assay results from weathered monzogranite containing disseminated pyrite mineralization. The strongest mineralized intercept to date, comprising 12 m at 2.38 g/t Au (including 1 m at 22.08 g/t Au), occurs adjacent to a contact between monzogranite and syenogranite intrusive phases. A similar intrusive contact localizes strain, hydrothermal alteration and gold mineralization at the São Jorge deposit. Mineralization remains open along strike and to depth.  

Preliminary processing of the recently completed 40 line km of IP surveying indicates that a broad east-west oriented high tenor chargeability anomaly, with coincident high resistivity, occurs at the William South target. Overall, the William South geophysical signature is similar in nature, scale and intensity to the São Jorge deposit. Drilling completed to date primarily targeted the highest tenor gold-in-soil geochemical anomaly, which occurs south of the core geophysical anomaly. Future drilling will extend northwards to test the chargeability / resistivity high.

Further RC drilling was subsequently completed at the Ivonette and Dragon West targets, to follow up on previously returned +1 g/t Au drill intercepts, with the objective to expand the mineralization intersected to date and potentially define new mineral resources. Assays are pending. Also, additional results from other components of the Program, including diamond core drilling beneath the São Jorge deposit, expansion of the IP survey grid, and a garimpo (artisanal mine) mapping and sampling program, will be reported as results are available.

Data Verification

For drill core sampling, samples were taken from the NQ/HQ core by sawing the drill core in half, with one-half sent to SGS Geosol Laboratórios Ltda. ("SGS") in Brazil for assaying, and the other half of the core retained at the site for future reference. Sample lengths downhole were uniformly 1.0 m. For the auger drilling program, samples were collected at 1 m sample intervals, with the material being dried, homogenized and split in the field to obtain a 1 kg representative sample which was sent to SGS for analysis. The remaining auger sample material is stored until the lab results are received, and a 1 kg sample duplicate is maintained in the archive. For the RC drilling program, samples were collected at 1 m sample intervals, generating approximately 25 kg samples, with the material being dried, homogenized and split in the field to obtain a 1 kg representative sample which was sent to SGS for analysis. The remaining RC sample material is stored until the lab results are received, and approximately 20 kg of the original samples are maintained in the archive.

SGS is a certified commercial laboratory located in Vespasiano, Minas Gerais, Brazil, and is independent of GoldMining. GoldMining has implemented a quality assurance and quality control program for the sampling and analysis of drill core and auger samples, including duplicates, mineralized standards and blank samples for each batch of 100 samples. The gold analyses are completed by FAA505 method (fire-assay with an atomic absorption finish on 50 grams of material).
