Geological mapping and rock chip sampling has identified several new multi-kilometre manganese-rich zones on the Ouangolodougou permit
Mapping delineated the location of these manganese-rich zones and identified others up to 400m wide on surface
Metallurgical testing and a complementary geophysical IP survey has kicked off
Special Report: A program of detailed geological mapping and rock chip sampling has turned up several multi-kilometre manganese-rich zones at Mako Gold’s Korhogo project in Côte d’Ivoire.
According to Mako Gold (ASX:MKG) managing director Peter Ledwidge, the results achieved from this low-cost mapping and rock chip sampling program add to the potentially significant discovery already made on the company’s Ouangolodougou permit at Korhogo.
In August 2023, eight shallow reconnaissance reverse circulation (RC) drill holes intersected wide zones of mineralisation up to 14.7% manganese, confirming the explorer had stumbled upon a “globally significant” manganese find.
What makes MKG’s discovery in Côte d’Ivoire especially fortuitous is the fact the country is one of the 10th largest producers of the metal, currently host to four producing manganese mines (national production of 36,000Mt in 2022), including Shiloh Mining’s Lagnonkaha operation, some 70km along strike from Korhogo.
Plenty more manganese to be found
A total of 122 rock chip samples were collected on outcropping manganese mineralisation over an area of 8km by 4 km, complementing the original 22 samples first reported in April 2023.
The purpose of the program was to identify the area of greatest potential by thoroughly mapping and sampling all outcrops along the twin 7km manganese-enriched zones originally discovered by preliminary mapping and subsequently confirmed by maiden drilling.
This mapping program delineated the location of the manganese-rich zones and identified new ones up to 400m wide on surface, while pXRF analysis on 143 samples returned average manganese values of 14.7% with values up to 25% manganese.
“These results confirm the continuity of manganese mineralisation over significant strike lengths as we prepare to further advance the project with metallurgical testing and a complementary geophysical IP survey that will greatly assist in future drill targeting,” Ledwidge says.
“Advancing the Korhogo project in this manner allows our experienced team to continue their successful exploration and discovery of new prospects on our flagship Napié Project.”

What else is happening at Mako?
Over at the Napié project, geological mapping and rock chip sampling continues at Tchaga North.
A new high-grade gold zone was discovered in late January 2024 with rock chip results up to 80g/t gold.
Ongoing detailed mapping at 100m spaced traverses is focusing on new prospective areas at Tchaga North, highlighted by the recent wide-spaced RC drill program.
MKG is particularly interested in the western contact between the greenstone and granite where limited drilling has returned values up to 1m @ 45g/t gold.
