Endeavour Mining plc Announces Tanda-Iguela Drill Results
Endeavour Mining plc announced that drill results obtained thus far from the extensive 180,000 metre drill programme currently underway at its Tanda-Iguela property, in Côte d’Ivoire, continue to demonstrate its potential to become Endeavour’s next cornerstone asset. A total of 123,514 metres have been drilled on the Tanda-Iguela property since the start of the year, which represents a significant increase over the 70,000 metres initially planned, with the programme expected to reach 180,000 metres by year-end as seven drill rigs are currently operating on site. The Company remains on track to publish an updated resource by late-2023, which is expected to incorporate the conversion of Inferred to Indicated resources, while the overall resource base is expected to materially increase. ASSAFOU DEPOSIT EXPLORATION PROGRAMME: Since its discovery in late 2021, more than 166,370 metres have been drilled on the Assafou deposit. Following the completion of the first drilling campaign, a maiden mineral resource comprising of an Indicated resource of 14.9Mt at 2.33g/t containing 1.1Moz and an Inferred resource of 32.9Mt at 1.80g/t containing 1.9Moz was published on 21 November 2022. Subsequently, an additional 108,370 metres have been drilled on the Assafou deposit, as part of the second drilling campaign through year-to-date 2023. An updated mineral resource estimate is expected to be published in late-2023, incorporating at least 165,000 metres of additional drill results, compared with 58,000 metres of drill results used to build the maiden resource. The 2023 Assafou drill programme is expected to convert Inferred resources to Indicated status whilst delineating new resources outside of the existing resource envelope. Drilling has proved the mineralised continuity within the Inferred resource boundary and the mineralised trend has now been defined over a length of 3.3 kilometres, extending from surface to depths exceeding 300 metres. As such, the maiden Indicated resources previously outlined over a strike length of 600 metres now. Cross Section 3200: Located outside the current Inferred resource boundary to the northwest: Further drilling 500 metres northwest of the Assafou Indicated resource boundary has confirmed the continuation of the Assafou mineralisation along the structural contact between the Tarkwaian Sediments and the Birimian Basement. Cross Section 3000: Located northwest of the current Indicated resource boundary: Northwest of the current Indicated resource boundary, further drilling has identified high-grade mineralisation below the current $1,500/oz pit shell, indicating that mineralisation remains open at depth and that there is potential to further extend resources. Cross Section 1933: Infill drilling within the existing resource boundary: Infill drilling within the existing resource boundary confirmed the high grade and thickness of the main mineralised lenses in close proximity to the structural contact with the Birimian basement rocks. In addition, further drilling highlighted the presence of deeper underlying lenses below the pit shell. Cross Section 1766: Infill drilling identifies additional mineralisation at depth below the current pit shell: Additional infill drilling returned high-grade intercepts within the Inferred resource boundary, confirming that thick lenses of high-grade mineralisation are continuous towards the southeast of the Indicated resource, with mineralisation extending to over 100 metres below the current pit shell depth. Cross Section 0866: Located at the southeast extent of the current Indicated resource boundary: Additional drilling has identified significant mineralisation towards the southwest at shallow depths, within 100 metres of the surface, and extending over 300 metres southwest away from the contact with the Birimian basement rocks. Cross Section 0433: Located southeast of the current Inferred resource boundary: Additional drilling has identified high-grade, thick continuous mineralisation approximately 2 kilometres southeast of the current maiden Indicated resource boundary and over 400 metres southeast of the current Inferred resource boundary. Mineralisation at the Assafou deposit is both disseminated and hosted in quartz veins, within the Tarkwaian sandstones. The deposit appears to be monometallic containing no potentially penalising elements associated with the gold. Mineralisation starts at surface and is continuous along strike, along the prominent northwest trending structure that separates the Tarkwaian sandstones from the Birimian mafic basement rocks. The deposit comprises a thick main (up to 60 metres) continuous lens, appearing to be generally dipping at a low angle to the southwest, overlaid by a series of stacked lenses, that extend down to over 200 metres depth. EXPLORATION ON TARGETS LOCATED NEAR ASSAFOU: In addition to further drilling on the Assafou deposit, a total of 20,000 metres was planned for Fiscal year 2023 to test high priority targets identified within a 5 kilometre radius of the Assafou deposit, with 15,143 metres of drilling completed year to date. Drilling has focused on identifying potential satellite deposits to Assafou, located within a similar geological setting, hosted along similar structural contacts between the Tarkwaian sediments and the Birimian basement. Along the Assafou structure, drilling has returned encouraging results on the Broukro, Kongodjan and Gbabango targets, highlighting that the Assafou mineralised trend potentially extends over 12 kilometres, from Kongojdan in the southeast to Gbabango in the northwest. At the Broukro target, located 1 kilometre to the southeast of Assafou, along the Assafou structural contact, additional reconnaissance drilling has identified a continuity of the Assafou mineralisation. At the Gbabango target, located to the northwest of Assafou along the Assafou structural contact, additional reconnaissance drilling has identified shallow mineralisation with further infill drilling required to test the continuity of mineralisation. At the Kongodjan target, located 4 kilometres to the southeast of Assafou along the Assafou structural contact, reconnaissance drilling has intercepted high-grade mineralisation. The presence of high-grade mineralisation at Kongodjan, suggests potential for a 3 kilometre-long untested corridor between the Broukro and Kongodjan targets as a new prospective target area. In addition, to the southwest of the Assafou structure, similar structural contacts have been identified through further drilling at the Pala Trend targets. At the Pala trend 2, located 4 kilometres west of Assafou, reconnaissance drilling has identified high-grade mineralisation over a 600-metre strike length. At Pala trend 3, located 1 kilometre west of Assafou, reconnaissance drilling has identified high-grade mineralisation over a 300-metre strike length.
