Highlights:

• Indicated Mineral Resource: 42.7 million tonnes ("Mt") at 26 grams per tonne ("g/t") gold equivalent ("AuEq") for 1.74 million ounces ("Moz") AuEq.
• Inferred Mineral Resource: 34.9 Mt at 0.93 g/t AuEq for 1.04 Moz AuEq.
• For the first time, antimony ("Sb") is modeled in the MRE and contributes approximately 25% of the Indicated AuEq oz and 29% of the Inferred AuEq oz.
• Estimated gold equivalent ounces in the Indicated category have increased by approximately 75% compared to the prior MRE from 2017*.
• The MRE is reported within a conceptual pit shell for the Project using long-term average prices of US$3,110/oz for Au and US$28,700/t for Sb.

Alastair Still, Chief Executive Officer of GoldMining, commented: "We are excited to update the Mineral Resource Estimate at Crucero, which has for the first time incorporated antimony, a critical metal globally recognized for its strategic importance. On a gold equivalent basis we have expanded Indicated resources by approximately 75% using a long-term average gold price of US$3,110 per ounce, well below current spot prices which are currently trading near US$5,000 per ounce. While we have always been encouraged by the exploration potential at Crucero, we have now demonstrated the emerging opportunity to unlock further value at the Project through the identification and quantification of antimony mineralization that is co-occurring with gold.”

*For comparison, the previous MRE (Effective Date December 20, 2017) comprised 30.6 Mt at 1.0 g/t Au for 0.99 Moz Au Indicated resources, and 35.8 Mt at 1.0 g/t Au for 1.1 Moz Au Inferred resources, at a gold price of $1,500 per ounce and a 0.40 g/t Au cut-off grade.

Updated Crucero Project Mineral Resource Estimate

Global Mineral Resource Services (“GMRS”) was retained by the Company to prepare an updated MRE and an independent technical report on the Crucero Project (see Figure 1) based on information current as of February 4, 2026 (the “Effective Date”). The purpose of the report is to support the disclosure of the updated MRE for the Project. The Company plans to file the NI 43-101 technical report, which will include further detail on the estimation methods and procedures, within 45 days of the date hereof.

The Crucero Project is located in Carabaya Province, in southeastern Peru at approximately 14° 11’ south latitude and 69° 50’ west longitude. The Project contains orogenic gold-antimony mineralization contained within metasedimentary rocks belonging to the Ambo and Ananea Groups of Lower Paleozoic age.

Exploration programs from 1996 to 2012 conducted by previous operators included geological mapping, soil and rock geochemistry, trenching, surface geophysical surveys, diamond drilling (79 holes over 24,773 m) and metallurgical testwork. Drilling was concentrated on one of the geophysical anomalies referred to as the A1 Zone where a total of 72 core holes for 22,712 m was completed. The Project is comprised of eight mining concessions with an aggregate area of 4,600 ha and is held in the name of Blue Rock Mining S.A.C. ("Blue Rock"), a wholly-owned subsidiary of GoldMining. The Company owns a 100% interest in the Property through their ownership of Blue Rock.

To date, exploration of the Project has concentrated on the A1 Zone. The A1 Zone as currently defined by trenching and drilling dips vertically to steeply to the east, is approximately 750 m along strike by 100 m in width in the central portion of the deposit, and has been traced to a vertical depth of approximately 400.

The A1 Zone is primarily hosted within meta-sediments (mudstones and siltstones) of the Ambo Group. Gold is the primary mineral of economic interest and occurs together with pyrite, pyrrhotite, arsenopyrite and stibnite which is the principal Sb-bearing mineral present. Pyrite is the most abundant sulphide and typically occurs as blebs, the distribution of which commonly appears to be along foliation or bedding. Quartz veins are uncommon and are not necessarily gold-bearing, although the highest gold grades found to date are associated with quartz veins.

The following table is a summary of the Crucero 2026 MRE update:

Table 1: Mineral Resource Estimate for the Crucero Project at 0.3g/t AuEq cut-off (Effective Date: February 4, 2026)

Notes:

1. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves.
2. Open pit resources stated as contained within a conceptual open pit above a 0.30 g/t AuEq cut-off.
3. Pit constraints are based on an assumed gold price of US$3,110/oz, an antimony price of US$28,700/tonne, metallurgical recoveries of 90% for gold and antimony, mining cost of US$2.50/t and processing cost of US$20.00/t.
4. Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
5. Mineral resource tonnages and grades are reported as undiluted.
6. Contained metal grades are in-situ and do not include process recovery losses.
7. CIM (2014) definitions were followed for classification of Mineral Resources.
8. AuEq (g/t) = Au grade (g/t) + (2.87 * Sb grade (%) x 90% recovery)
