As of 8 May 2024, following the execution of the memorandum of understanding between the Government, Leo, GFL International Co., Ltd(Ganfeng), Firefinch, Mali Lithium B.V (MLBV), and Lithium du Mali SA (LMSA), Firefinch is in the process of negotiating a sale agreement with Sorem SA in respect of the sale of Firefinch’s interest in Morila SA and its other mining titles.
The Morila permit is situated in the northern portion of the West African craton between the NNE trending Birimian volcano-sedimentary belts of Kalana-Yanfolila and Syama. The region is underlain predominantly by Lower Proterozoic meta-volcanic and metasedimentary sequences (Birimian) and large areas of granitoids. The whole package of rocks has been deformed by the Eburnean Orogeny. The permit area locates along a contact between Birimian metasediments and the Eburnean granitoids.The Morila orebody is developed within upper greenschist to amphibolite facies of pelitic and psammitic rocks. Their mineralogy is dominated by biotite (30%), plagioclase (30%) and quartz (30%). The package has been intruded to the southwest by a tonalite body similar in composition to the Morila sediments. The sediments have been locally metasomatised by the tonalite to produce a feldspar porphyroblastic texture.Arsenopyrite is generally associated with mineralisation and is by far the most dominant sulphide (80%) followed by lesser amounts of pyrrhotite (15%) and pyrite (5%) The pyrrhotite is ubiquitous throughout the metasediments and occurs as irregular grains which often contain inclusions of chalcopyrite. It is not uncommon for visible gold to be present.Gold mineralisation is predominantly associated with coarse arsenopyrite, occurring as individual grains on arsenopyrite grain boundaries or as intergrowths or as free gold in a silicate mineral matrix in the proximity of arsenopyrite grains. A small percentage of the gold occurs as inclusions within the sulphides and occasionally the gold is locked within silicate minerals (<5%).Mineralisation is hosted in a sequence of relatively flat lying stacked veins located 70 - 130m below surface. Mineralisation does steepen due to shearing and faulting in certain places.Various theories have been derived for the genesis of mineralisation at Morila and several internal and academic studies have been completed and published. Most agree that the key factors influencing the location of mineralisation are competency contrasts in the host sediments (fine grained vs coarse grained), fluid and heat from proximal granitoids, and proximity to regional structures.The N’Tiola, Viper and Koting deposits are shear vein hosted orogenic style gold deposits. This style of mineralisation typically forms as veins or disseminations in altered host rock. Deposits of this type often form in proximity to linear geological structures.Surficial geology within the project area typically consists of indurated gravels forming plateau, and broad depositional plains consisting of colluvium and alluvial to approximately 5m vertical depth. Lateritic weathering is common within the project area. The depth to fresh rock is typically 35m vertical.
