Exploration Target of Adumbi Underground estimated to be in the range of 8.9 million tonnes to 9.6 million tonnes grading from 4.7 g/t Au to 4.9 g/t Au below USD1,600/oz pit shell
Toronto, Canada – January 25, 2024 – Loncor Gold Inc. ("Loncor" or the "Company") (TSX: "LN"; OTCQX: "LONCF”; FSE: "LO51") is pleased to announce that drilling tenders have been sent to a number of drilling companies to bid on a 11,000-metre-deep drilling program at its priority gold exploration target below the Adumbi USD1,600/oz pit shell. It is proposed that two core rigs will commence a deep drilling program at Adumbi by the beginning of April 2024. Adumbi is situated 220 kilometres from Africa’s largest gold mine, the Barrick Gold/ AngloGold Ashanti Kibali Gold Mine, a hub for many major mining related contractors in the DRC.
Fifteen intersections are proposed below the pit shell in order to outline an inferred underground mineral resource (see Figure 1 below showing intended 15 drill interceptions below the Adumbi pit shell). Of the fifteen proposed intersections, six interceptions will be wedged off nine deeper holes in order to save time and costs. This drilling program is estimated to be completed by year end at which time an underground inferred mineral resource estimate will be carried out.
Adumbi currently has an indicated mineral resource of 1.88 million ounces of gold (28.185 million tonnes grading 2.08 g/t Au), and an inferred mineral resource of 1.78 million ounces of gold (20.83 million tonnes grading 2.65 g/t Au) – all within the USD1,600/oz pit shell, with 84.68% of these mineral resources being attributable to Loncor.
Loncor’s Chief Executive Officer, John Barker, commented: “The recent non-dilutive sale of Makapela for CAD$13,500,000 has strengthened Loncor’s hand significantly. It allows us to drill for the potential ounces below the 3.66 million-ounce, high grade resource delineated within the Adumbi pit outline.
Additionally, confirmation of significant ounces at depth would allow Adumbi the flexibility to explore the economics of a combined open pit and underground project. A smaller pit would reduce strip ratios, and the underground ounces would increase the grades through the processing plant with the overall target being an enhanced economic profile for the combined open pit and underground scenario.
With the recent DRC general elections passing successfully, the country continues to draw growing interest from international companies seeking world class mineral and mining opportunities. We believe the developing Adumbi places Loncor at the forefront of such interest.”
The Adumbi resource remains open at depth below the USD1,600/oz pit shell (maximum depth of pit shell bottom 550 metres below surface) with the favourable Banded Ironstone Formation (BIF) host increasing in thickness. As stated in the Company’s press release of December 19, 2023, the Company estimates the potential Adumbi underground exploration target as between 8.9 million tonnes to 9.6 million tonnes grading 4.7 g/t Au to 4.9 g/t Au to a depth of 800 metres (reference is made to the said press release, which can be found at SEDAR+ at www.sedarplus.ca, for additional information with respect to this estimate). These potential quantities and grade are conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the Adumbi underground exploration target being delineated as a mineral resource.
