GoldMining Inc. Reports Final Drill Assay Results from the Previously Announced Diamond Drilling Program, and A Progress Update for the Ongoing Auger Drilling Program, at the Company's 100% Owned São Jorge Project in the Tapaj's Gold District
GoldMining Inc. reported final drill assay results from the previously announced diamond drilling program, and a progress update for the ongoing auger drilling program, at the Company's 100% owned São Jorge Project ("São Jorge" or the "Project") in the Tapajós gold district ("Tapajós"), Pará State, Brazil. The Company commenced drilling at São Jorge in May 2024. The objectives of the program included confirmatory drilling within and near the margins of the existing São Jorge gold deposit (the "Deposit"), as well as exploratory drilling of identified gold targets within 1-2 km of known mineralization in areas with no previous drilling. The diamond core drilling component of the program consisted of 1,077 m over five holes, and the ongoing 3,000 m auger drilling program is approximately two thirds complete, with assays received from approximately one third of the projected program. Assay results for the latest two diamond drill holes (SJD-123-24 and SJD-124-24) have been received, which combined with the previously released holes, SJD-120-24 to SJD-122-24, successfully concludes the current phase of diamond core drilling planned for São Jorge. The latest holes have identified new gold and copper mineralization approximately 1 km northwest of the existing deposit in an area that had not been previously drilled. Ongoing auger drilling, focused in an area located approximately 2 km north of the São Jorge deposit to follow up on the large high tenor 'William South' gold-in- soil anomaly, has returned very encouraging indications of primary gold mineralization in bedrock which highlights that the large, regional-scale property has potential to host additional corridors of mineralization that can be further tested by core drilling. São Jorge lies within the active and rapidly developing Tapajós Gold District, which is estimated to have produced over 20 million ounces of gold historically from artisanal mining of surface deposits, according to the Brazil National Mining Agency. The Tapajós is home to Serabi Gold Plc.'s producing high- grade underground Palito Mine and G Mining Ventures Corp.'s ("G Mining") brand new Tocantinzinho Gold Mine, which recently declared commercial production. São Jorge is located immediately adjacent to paved Hwy BR-163 and a new 138 kV powerline corridor, which ties into the district electrical grid recently constructed for the Tocantinzinho Gold Mine. Exploration activities at São Jorge are operated from a permanent camp near the existing Deposit and just 3 km from the highway. Highlights of the confirmatory component of the drilling program included drill holes SJD-120-24 with an interval of 163 m at 1.02 g/t Au, and SJD-121-24 and SJD-122-24 with intervals of 18 m at 0.70 g/t Au and 19 m at 1.24 g/t Au respectively. SJD-123-24 and SJD-124-24 - new drilling reported in this release - comprised step-out drilling located approximately 1 km to the northwest of the Deposit, testing coincident geochemical and geophysical anomalies interpreted to form an extension of the São Jorge high-strain corridor. SJD-123-24 and SJD-124-24 tested strong and broad gold- and copper-in-soil surface anomalies, respectively. Gold mineralization encountered in SJD-123-24 is similar in style to that in the São Jorge deposit, comprising fracture-controlled sulphide ± quartz veins, with the sulphides consisting of dominant pyrite with lesser chalcopyrite. This helps support geological model that gold mineralization may extend along a broad high- strain corridor co-incident locally with a contact between monzogranite and syenogranite The sheared contact between monzogranite and syenogranite, which at the Deposit forms the southern boundary of the São Jorge high-strain corridor, was not intersected in the shallow depth drilled in SJD-123-24, thus follow-up drilling is warranted both across and along strike. The elevated copper encountered in SJD-124-24 is interpreted as a possible hydromorphic dispersion layer in saprolite, formed from the in situ weathering of granitoid rock and the redistribution of mobile metals by ground water. It may form a horizontal blanket-shaped plume of elevated copper, concentrated between the base of complete oxidation ("BOCO") and top of fresh rock ("TOFR"), which is the typical location for hydromorphic mobilization of soluble metals in a lateritic weathering profile such as in the Tapajós district of the Brazilian Craton. The strongly anomalous Cu zone in SJD-124-24 contains approximately 20 times the typical background of copper levels normally found in granitoid rocks, and the location, continuity and tenor of the anomalous copper values may indicate an underlying bedrock source of copper mineralization in close proximity. Deeper sections of SJD-124-24 intersected thin discrete sulphide bearing veins with dominant pyrite and chalcopyrite, thus confirming a possible source of the elevated copper in bedrock. Hydromorphic dispersion halos may extend for 10s to 100s of meters from the source bedrock mineralization, therefore follow-up drilling is warranted to further explore and confirm the potential source, tenor and style of copper mineralization responsible for the broad halo of copper enrichment in the weathering profile. A power auger drilling program comprising an initial program of 3,000 meters for approximately 200 holes is underway at the Project. The auger program is initially targeting the high priority 'William South' area located approximately 2 km north of the São Jorge deposit. William South comprises a broad high-tenor zone of anomalous gold-in-soil, measuring approximately 2 km x 2 km with soil assays peaking at 2,163 ppb Au (2.163 g/t Au). To date assays have been received for 101 holes completed at the William South target. From the initial drill results, approximately 25% of all holes have returned assay results greater than 100 ppb (0.1 g/t) Au, confirming the presence of gold mineralization in weathered bedrock. Note that background gold values in both residual weathered bedrock and overlying transported soils, is expected to range from nil to 1-2 ppb Au, thus values of greater than 10 -25 ppb Au are considered to be 'elevated' and greater than 100 ppb Au to be 'highly anomalous'. The auger drilling comprises a powered 20 centimetre diameter rotary drill head capable of penetrating to 15-20 m depth. A geologist or technician supervises the drilling to log the drill cuttings and distinguish transported overburden from in situ weathered bedrock. Sampling is conducted on 1 m intervals with assaying to 5 ppb Au detection. The drill method is open-hole, therefore contamination and/or dilution of precious metal grades by material from higher in the hole is possible.
