The Sonora Lithium Project consists of ten contiguous concessions covering 97,389 hectares. Two of the concessions
(La Ventana, La Ventana 1) are owned 100% by Bacanora through its wholly-owned subsidiary Minera Sonora Borax
S.A de C.V. (“MSB”). El Sauz, El Sauz 1, El Sauz 2, Fleur and Fleur 1 concessions are owned by, Mexilit S.A. de
C.V. (“Mexilit”) (which is owned 70% by Bacanora and 30% by Cadence). These concessions are located
approximately 190 kilometres northeast of the city of Hermosillo, in Sonora State, Mexico. They are roughly 170
kilometres south of the border with Arizona, USA. The San Gabriel and Buenavista concessions are owned by Minera
Megalit S.A. de C.V. (“Megalit”) (which is owned 70% by Bacanora and 30% by Cadence). The asset has Measured
plus Indicated Mineral Resource estimate of over 5 million tonnes (‘Mt’) (comprising 1.9 Mt of Measured Resources
and 3.1Mt of Indicated Resources) of lithium carbonate equivalent (‘LCE’) and an additional Inferred Mineral
Resource of 3.7 Mt of LCE, Sonora is regarded as one of the world’s larger known clay lithium deposits.
Key Operational Highlights on the Sonora Project are as follows:
? Published its Feasibility Study (“FS”) on the project. The FS targeted a two-stage open-pit operation,
reaching 35,000 tonnes (t) of lithium carbonate (Li2CO3) per annum (“tpa”) in year four.
o The FS has a pre-tax NPV of US$1.25 billion and an IRR of 26%. The capital and working capital
costs of the first stage of production (17,500 t of Li2CO3 per annum) is estimated to be US$460
million.
o Under our estimation, The FS mine plan currently has some 12% of the plant feed being mined
from the 30% joint venture areas owned by Mexalit.
