Bacanora Finalizes Lithium Farm-in Deal With Rare Earth Minerals Plc on El Sauz and Fleur Lithium Concessions and Commences Diamond Drilling

CALGARY, ALBERTA -- (Marketwired) -- 05/22/13 -- BACANORA MINERALS LTD. ("Bacanora" or the "Company") (TSX VENTURE: BCN) is pleased to announce that it has executed formal agreements with Rare Earth Minerals Plc ("REM"), a London Stock Exchange listed company (AIM: REM), pursuant to which it has granted REM certain rights to participate in drilling and project evaluation of the El Sauz and Fleur Lithium concessions (the "Concessions" or individually, a "Concession") in northern Mexico per the Company's February 14, 2013 news release. The Concessions are adjacent to and along strike from the Company's La Ventana Concession.

Highlights of the Agreement:

--  REM will earn an initial 10% interest in Bacanora's 100% owned
    subsidiary that will hold the Concessions by making an upfront cash
    payment of $250,000 (which has been received by Bacanora) and providing
    another $500,000 to the Company in two instalments, to be used for
    exploration and drilling on the Concessions and delivered in full no
    later than 4 weeks after drilling starts.

--  Following completion of the above, REM shall have an option to increase
    its interest in the Company's subsidiary to 30% by providing written
    notice of exercise, together with delivery of an additional cash payment
    of $500,000, on or before August 11, 2013, and thereafter depositing a
    further $1,000,000 within 6 months of exercise of this option, which
    funds shall be used for drilling and exploration expenditures on the
    Concessions.

--  Following completion of the prior two stages, REM will thereafter have
    an exclusive option to negotiate terms to increase interest in the
    subsidiary holding the Concessions from 30% to a maximum of 49.9%.

Drilling Update:

Bacanora is also pleased to announce that a diamond drill under contract from Godbe Drilling of Colorado, USA has arrived on the Concessions. The drill is set up and has commenced drilling the first of 10 holes on the Concessions.

The initial diamond drilling will consist of approximately 2,500 metres of NQ core in 10 holes, which will have the following objectives:

--  Test the thickness and extent of the clay units exposed on El Sauz
    Concession;
--  Provide an initial estimate of the lithium content of these units at
    depth;
--  Determine if the clay units on El Sauz continue to the north and onto
    the Fleur Concession; and
--  Determine if the clay units on the Concessions are the same units as
    those exposed on the adjoining La Ventana concession.

The drilling programme is estimated to take approximately 80 days, with final results of drill core analyses expected in roughly late August.

In conjunction with the drilling, mapping and rock sampling will resume on the Fleur Concession in order to provide the Company with a full assessment of the lithium potential of this Concession. Previous surface rock sampling, as announced April 10, 2013, demonstrated that exposures with lithium values range from 10 to 7,220 ppm Li (3.84% LCE(i)), with 10 samples greater than 2,168 ppm (0.95 percentile). The samples also have values in potassium which range from 0.04% to 3.07%, as well as other alkali metals. Results of geological mapping have delineated exposures of the sedimentary-volcanic succession that hosts the lithium-bearing clay units cover an area of 80 hectares in an arcuate belt approximately 2 km long in a northwesterly direction and 1 km in width. Sediments on the southwest side of the arc dip gently to the southwest, whereas those on the northeast dip to the northeast.

About the Sonora Lithium Project:

The Company's interests in El Sauz and Fleur Concessions cover 3,411 hectares out of a total of 5,786 contiguous hectares that make up the Sonora Lithium Project (the "Project") owned by Bacanora.

Initial rock sampling and mapping of the Project by Bacanora located the lithium-bearing clay units within a sedimentary-volcanic sequence. Drilling by Bacanora in 2010 and 2011 located two lithium-bearing clay units (upper and lower) that average 41 and 22 m in thickness, respectively, and that are separated by an ignimbrite unit varying from 1 to 45 m in thickness. The sedimentary-volcanic sequence dips at approximately 20 degrees to the east and crops out along 3.5 km of strike length. The exposures are in erosional windows looking through overlying basalt that covers much of the area. The lithium-bearing clay minerals have been identified as hectorite and polylithionite.

Within the Project area on the La Ventana concession that is 100% owned by Bacanora and adjoins the ground under option to REM, National Instrument 43-101 ("NI 43-101") compliant inferred resources have been estimated for two clay units (referred to as the "La Ventana Lithium Deposit"). The inferred resources for the two clay units total 60 million tonnes averaging 3,000 ppm Li (equivalent to 1.6% lithium carbonate assuming 100% recovery and no process losses). Bacanora has used the inferred resources on the La Ventana Lithium Deposit for a Preliminary Economic Assessment ("PEA") of the concession (refer to Bacanora news release dated January 25, 2013). Highlights of the PEA for a potential lithium mining and production operation with an output of 35,000 tonnes battery grade lithium carbonate per annum over a 20 year open pit mine life suggest annual revenue of $US210 million for an Internal Rate of Return of 138%, with a 1.9 year pay back. Capital costs are estimated at $US114 million and average operating costs at $US1,958/tonne. Net present value of the Project, discounted at 8%, is $US848 million, assuming an average lithium carbonate price of $US6,000/tonne.

Management is very pleased with the results to date which merit advancing the El Sauz project to the first drill testing of lithium bearing clay units on this property. Should the outcropping lithium clays on El Sauz be found to correlate with those on the Company's La Ventana Lithium Deposit, then a reasonable inference will be capable of being made based on available geological evidence that the sedimentary basin that hosts the lithium-rich clays extends, in a northwesterly direction, for at least 7 kilometres.

Lithium is the lightest of the alkali metals and has unique electrochemical properties that make it the element of choice for batteries of high energy storage capacity and other energy applications as well as a host of other industrial and health applications.

(i) LCE = lithium carbonate (Li2CO3) Equivalent: determined by multiplying
    Li value in percent by 5.324 to get an equivalent Li2CO3 value in
    percent. Use of LCE assumes 100% recovery and no process losses in
    conversion of Li to Li2CO3.
