GoldMining Inc. (the "Company" or "GoldMining") (TSX:GOLD) (NYSE:GLDG) is pleased to announce initial assay results from the first two holes of a six hole 3,600 metre (m) drilling program on the La Garrucha target, located less than one kilometre to the east and immediately adjacent to existing mineral resources on the Company's 100% owned La Mina project ("La Mina"), located in Antioquia, Colombia.  Highlights The assays presented herein are for the first step-out drill section located 100 metres along strike of previously identified porphyry-style mineralization at La Garrucha.  LME1107        207.95 m at 0.48 g/t Au and 0.10% Cu (0.62 g/t AuEq) from 261.60 m depth Including           57.17 m at 0.60 g/t Au and 0.13% Cu (0.79 g/t AuEq) from 282.75m depth And                  70.89 m at 0.60 g/t Au and 0.10% Cu (0.74 g/t AuEq) from 387.21 m depth LME1108        345.54 m at 0.57 g/t Au and 0.12% Cu (0.74 g/t AuEq) from 254.95 m depth* Including          59.45 m at 0.76 g/t Au and 0.19% Cu (1.04 g/t AuEq) from 328.92 m depth And                  61.8 m at 0.81 g/t Au and 0.11% Cu (0.97 g/t AuEq) from 538.69 m depth* *LME1108 ended in mineralization Alastair Still, CEO of GoldMining, commented, "This is a great start for our 2022 La Garrucha drilling program at the La Mina Project in Colombia and our broader strategy to unlock value from our portfolio of gold and gold-copper projects located throughout the Americas. This also builds upon the La Mina Preliminary Economic Assessment* announced earlier this year that focused on the La Cantera and Middle Zone deposits of the project which are located 1 kilometre to the west of La Garrucha. Our team believes that the La Garrucha target remains open for expansion and is shaping up as a third possible porphyry deposit which could contribute potential additional resources to lead the growth of the La Mina Project." Tim Smith, VP Exploration of GoldMining, commented, "These results from the first two holes of our 3,600 metre drilling program (announced April 12, 2022) confirm that the La Garrucha porphyry mineralization extends to the southeast along strike as modelled from our geophysical dataset and interpreted by our technical team. Drilling is continuing on the next two drill fences located on 100 metre step outs southeast along strike. We expect that those assay results will be released in the coming months as they become available. With the association between bedrock magnetic highs and porphyry-style mineralization now confirmed, we are further encouraged by the presence of additional magnetic targets located within the broader La Mina property which will be systematically explored for additional Au-Cu porphyry mineralization."  *The Preliminary Economic Assessment referenced above, announced January 12, 2022, is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Drill Program Details and Geological Description The ongoing La Garrucha drilling program is targeting a large (1km x 1km) magnetic high associated with a granodiorite porphyry intrusive complex that hosts gold and copper mineralization at La Garrucha (see Figure 1). A smaller discrete magnetic high is also coincident with the nearby La Cantera Au-Cu porphyry deposit. Previous La Garrucha drilling completed in 2011 by Bellhaven Copper & Gold Inc. ('Bellhaven'; prior to acquisition by GoldMining) returned gold-copper porphyry intercepts of 216.80 metres at 1.31 g/t Au and 0.15% Cu from 143.0 to 359.80 metres depth in LME1100;  158.12 metres at 1.01 g/t Au and 0.17% Cu from 66.50 to 224.62 metres depth in LME1102;  and 71.0 metres at 1.02 g/t Au and 0.14% Cu from 355.0 to 426.0 metres depth and 106.60 metres at 0.56 g/t Au and 0.11% Cu from 485.65 to 592.25 metres depth in LME1104.  Drill holes LME1107 & 1108 were drilled on a NE-SW oriented section located 100 metres southeast of the previous Bellhaven drilling at an azimuth of 220⁰ and at hole inclination of -50⁰ and -70⁰ hole respectively (see Figure 2). Drilling has confirmed the continuation of porphyry mineralization southeast along strike. Gold and copper mineralization is coincident, and higher grades are associated with a core potassic alteration zone within the porphyry intrusive complex, quartz stockwork veining and both vein-hosted and disseminated sulphides including pyrite, chalcopyrite and lesser bornite. Detailed core logging is ongoing, including re-logging of the previous Bellhaven core, to place copper and gold mineralization in spatial and temporal context with the hosting porphyry intrusive complex. Geological 3D modelling and subsequent resource modelling will take place in the latter part of the year following conclusion of the drilling program. The La Garrucha porphyry mineral system now extends over at least 300 metres strike, where it is open to the southeast, and over at least 200 metres width. Drilling has tested to a maximum vertical depth of 450 metres below surface where the porphyry mineral system remains open to depth.  Step-out drilling is currently ongoing on a second drill fence located 100 metres along strike to the southeast of LME1107 & 1108. A third fence is planned an additional 100 metres southeast along strike pending visual observations of the drill cores. In addition, the drill will return to the LME1107 & 1108 drill pad to re-enter and deepen LME 1108 given that core assays indicate that the hole ended in mineralization.
