GoldMining Updates Mineral Resource Estimate with Inclusion of Antimony

at its Crucero Gold Project, Peru

VANCOUVER, BC

Feb. 17, 2026

/CNW/ -

GoldMining Inc.

(TSX: GOLD) (NYSE American: GLDG) ("GoldMining" or the "Company") is pleased to report an

updated Mineral Resource Estimate (the "MRE") on its 100% owned Crucero Project ("Crucero" or the "Project") in Carabaya Province,

Peru

. The updated MRE

has been prepared under National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101").

Highlights:

Indicated Mineral Resource: 42.7 million tonnes ("Mt") at 1.26 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.

Notes:

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.

Open pit resources stated as contained within a conceptual open pit above a 0.30 g/t AuEq cut-off.

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.

Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.

Mineral resource tonnages and grades are reported as undiluted.

Contained metal grades are in-situ and do not include process recovery losses.

CIM (2014) definitions were followed for classification of Mineral Resources.

AuEq (g/t) = Au grade (g/t) + (2.87 * Sb grade (%) x 90% recovery)
