New Mozambique Lithium Licenses
ASX: Li3 9 July 2019
-
Expansion of land position through the grant of three additional licenses, including the strategically significant 9166L license
-
Outcropping pegmatites have significant potential for extensions at shallow depths, which can be confirmed through modern lithium-focussed exploration
-
Mozambique is on the east coast of Africa, with multiple bulk-handling ports and well-developed road and rail infrastructure for mining
-
Mozambique is a pro-mining jurisdiction
-
Li3 remains the first and only ASX listed company to enter Mozambique for hard rock lithium
Further to the announcement dated 25[th] March 2019 Lithium Consolidated Ltd (“ Lithium Consolidated ”, “Li3” or the “ Company ”) is pleased to announce it has been granted three (3) new lithium exploration licenses in the Alto Ligonha Pegmatite Province in northern Mozambique (the “ Mozambique Licenses ” or “ Licenses ”) (see Figure 1).
The three (3) newly granted Licenses are in addition to the two (2) Licenses, which were granted and announced on 25 March 2019, such that the Company now holds a total of five (5) Licenses over an area of 31,481 ha (314.8 km[2] ) in the Alto Ligonha Pegmatite Province (“ ALPP ”) in Mozambique.
The ALPP contains a large concentration of pegmatites, including many examples of L ithium C aesium T antalum (“ LCT ”) family of pegmatites, which have been mined since the 1920’s.
Mozambique was the world’s second largest beryl producer in the 1960’s, but the lithium-bearing minerals were not exploited from the same pegmatites during the historical beryl and tantalite mining.
The ALPP’s current exploration maturity is analogous to that which existed in the Pilbara and Yilgarn Craton pegmatites of Western Australia, approximately 10 years or so ago,
prior to the modern lithium-focused exploration, which resulted in the definition of large lithium resources in the Pilgangoora, Wodgina, and Earl Grey pegmatites.
Northern Mozambique has well-developed infrastructure for mining. The Mozambique Licenses are in close proximity to the Mocuba – Nampula main road, a sealed, all weather road. The recently upgraded Nacala railway corridor connects Nampula to the natural deep-water port of Nacala, which is the principal port for the export of coal from mining operations at Moatize.

Note:
(a) Additional Licenses under application for new areas of interest.
License 9166 L
License 9166 L is located approximately 50km northeast of Alto Molocue and is situated on an interpreted pegmatite not recorded in prior maps of the region (Figure 2).
The area comprises undifferentiated rocks of the Nampula Complex, banded biotite gneisses and migmatitic biotite gneisses.
Satellite imagery interpretation and analysis has identified extensive artisanal workings which appear to be located on a potentially large pegmatite body. The extent of the artisanal workings and the spectral response within the satellite imagery indicates the possibility of a large pegmatite body within the license area that requires field checking.

License 9168L
License 9168L is located in the northeast of the ALPP within the Alto Ligonha pegmatite field (Figure 3a and b) in close proximity to License 9190L.
The host rocks to the pegmatites largely comprise of gneisses from the Mamala Gneiss, the Molócuè Group and the Culicui Suite of the Nampula Complex.
The Molócuè Group comprises metapelites and metapsammites with subordinate interlayered marble, calc-silicates, felsic and mafic rocks and host the majority of the known lithium mineralized pegmatites in the region. The younger granites of the Murrupula Suite are considered to be associated with the pegmatites, and outcrop to the east of the license area.
Tracts of artisanal workings have been interpreted from satellite imagery over four (4) distinct areas within the license boundaries. Three (3) of these are over pegmatites within the Ingela pegmatite occurrence.
Beryl and tantalite-columbite series minerals have been reported from the Ingela pegmatites.

License 9188 L
License 9188 L is located in the northern part of the ALPP within the Nauela Pegmatite Field (Figure 4a and b).
The license area is largely underlain by granitic gneisses from the Culicui Suite. Other rock types within the area include amphibolite, mafic gneisses, and various biotite gneisses from the Mocuba complex.
Three pegmatite clusters are known within the large license area: Guilherme, Malapa, and Muetia. Two of these have been identified as having workings over them through satellite imagery interpretation. Only a small number of features representing possible workings can be interpreted in the area of the Muetia cluster. The pegmatites are described as belonging to the sodalithic class (which corresponds to the LCT family of pegmatites).

Alto Ligonha Pegmatite Province Geology
The Alto Ligonha Pegmatite Province has:
-
Pegmatites famous for their gemstones, rare-element minerals such as beryl, columbo-tantalite, and for being a source of rare and unique mineral specimens. Certain of these pegmatites also contain lithium minerals that have not previously been exploited;
-
outcropping pegmatites, including a number of abandoned historical workings, which have significant potential for extensions at shallow depths, which can be realized through modern lithium-focused exploration; and
-
the potential for delineation of larger, pegmatite hosted lithium mineralisation through modern lithium-focused exploration.
The Alto Ligonha Pegmatite Province is largely located in the NNE - SSW trending Namama Thrust Belt/Shear Zone and extends from Mocuba in the southwest to approximately 100km northeast of Alto Molocue in the northeast in the Zambézia Province of northern Mozambique (Figure 5).
The geology is dominated by rocks of the Nampula Complex within the Mesoproterozoic Mozambique Belt, predominantly medium to high-grade gneisses. These rocks were reworked during the Pan-African Orogeny involving the amalgamation of east and west Gondwana. The orogeny involved the emplacement of several nappe sheets, which have been preserved, followed by deformation, metamorphism and granitic magmatism. The pegmatites were emplaced late to post-orogenic and are distributed in four main zones, of which three coincide with major structural features (see Figure 5).
Figure 5 – Geology of the ALPP (Source: Macey et al, 2010)
==> picture [529 x 390] intentionally omitted <==
Many of the pegmatites have characteristics of the LCT family, and some have characteristics of the NYF ( N iobium- Y ttrium- F luorine) family. The LCT family can be further subdivided into sodalithic and potassic beryl types, corresponding to the Complex and the Beryl types of Cerny (1991) respectively. Both of these types can be defined to belong to the Lithium subclass of the Rare-Element pegmatites. The sodalithic type pegmatites considered to be the most prospective for lithium mineralization. Other types of pegmatites present include potassic rare-earth amazonite and tourmaline bearing sub-types (which belong to a mixed NYF-LCT family of pegmatites) and do not contain lithium mineralization.
The ALPP is known to contain several large sodalithic-type pegmatites (LCT pegmatites) that are currently being mined on a small scale, and which were previously mined for tantalite and gemstones. A number of these are currently also being explored for their lithium potential.
The sodalithic pegmatites are preferentially hosted in the paragneisses of the Molócuè Group which comprises metapelites and metapsammites with subordinate interlayered marble, calc-silicates, felsic and mafic rocks.
The Company’s exploration focus will be on the definition and capture of large, previously unexplored or previously under-explored pegmatites of the sodalithic type, with an emphasis on definition of unmined, concealed, shallow extensions.
Potential targets have been identified through historical data, satellite imagery interpretation and exploration programmes will now be focused on systematic mapping, sampling, and if initial appraisal is encouraging, evaluation through drilling.
