GoldMining Inc. Begins 2026 Exploration Drilling at Yarumalito

GoldMining Inc., listed on both the TSX under the ticker GOLD and on NYSE American as GLDG, has officially launched its 2026 exploration drilling program at its fully owned Yarumalito Gold-Copper Project in Colombia. This initiative marks an important phase in advancing the understanding of the region's geological potential and aims to build upon previously identified targets.

Overview of the Yarumalito Project

Located in the Mid Cauca gold-copper belt of Antioquia, Colombia, the Yarumalito project is situated approximately 105 kilometers south-southwest of Medellín, which is Colombia's second-largest city and a key economic hub. The project is in close proximity to significant mining operations, such as Collective Mining's Guayabales project and Aris Mining's Marmato mine. The rich mineralization in the area is attributed to porphyry intrusive bodies of potassic altered diorite, which host disseminated and fracture-controlled pyrite, chalcopyrite, and other minerals.

Previously, GoldMining conducted extensive research on the property based on 50 historical drill holes drilled between 2005 and 2013, providing a solid foundation for their current exploration efforts. The existing mineral resource estimate indicates approximately 66.3 million tonnes of resources at 0.58 grams per tonne of gold and 0.09% copper.

The Current Drilling Campaign

The new drilling program is fully funded and is expected to include a systematic approach to drilling over approximately 1,200 meters. This strategy focuses on testing high-priority exploration targets identified from thorough relogging of historical core samples. The drilling will delve into previously underexplored zones of the P-1 porphyry unit, the primary host for gold-copper mineralization in the region.

Historically, drilling intercepts have yielded promising results, including:

• - 257 meters at 0.50 grams of gold per tonne and 0.1% copper from the surface (YAR-06)
• - 250 meters at 0.51 grams of gold per tonne and 0.13% copper from the surface (YAR-08)
• - 141.4 meters at 0.77 grams of gold per tonne and 0.09% copper from the surface (YAR-11)

These promising past results set the stage for continued investigation into the potential of the Yarumalito project.

Strategic Significance

Alastair Still, CEO of GoldMining, expressed enthusiasm regarding the exploration efforts, emphasizing that Yarumalito is strategically located within the prolific Mid Cauca belt. With diamond core drilling now underway, GoldMining is looking to unlock significant growth potential from the P-1 host unit, further validating the project's prospective value.

As part of this drilling campaign, additional holes will target epithermal veins that have been mapped from historical underground workings. This step will help assess the width, geometry, and grade characteristics of the mineralization that exists within these veins, enhancing knowledge about Yarumalito's comprehensive mineral profile.

Future Outlook

GoldMining Inc. continues to identify and develop gold assets throughout the Americas. This latest initiative at Yarumalito reflects the company's disciplined acquisition strategy and commitment to unlocking the vast potential of its exploration properties.

As drilling progresses, stakeholders and potential investors will be closely monitoring developments to assess how the outcomes may impact GoldMining’s position in the market and the future of mineral exploration in Colombia.

In conclusion, the initiation of the drilling program at Yarumalito is a significant milestone for GoldMining Inc. and serves to reinforce its commitment to exploring and developing key mineral resources in Central and South America.
