Bacanora Minerals Ltd.: New Alkali Metal and Alkali Earth Metal Inferred Resources Declared for El Sauz and Fleur Concessions

CALGARY, ALBERTA--(Marketwired - Nov. 25, 2013) - BACANORA MINERALS LTD. (TSX VENTURE:BCN) ("Bacanora" or the "Company") is pleased to announce that it has received analytical results for alkali metals and alkali earth metals from drilling conducted on the El Sauz and Fleur concessions (the "Concessions") under joint venture with Rare Earth Minerals PLC ("REM"). The additional analytical data is being used by the Company to declare new inferred resources for potassium, rubidium, cesium, magnesium and strontium within the resource previously estimated for lithium.

The analytical results were obtained from pulps of core samples previously analysed in connection with the Company's lithium (Li) drilling programs, which were re-analysed by ALS Global, an internationally recognized and ISO accredited laboratory, using method ME-MS81(1), in order to achieve better definition of alkali values above detection limits of the previous analytical method that was used in connection with Li analyses (ME-MS41(2)).

The ranges of values across the clay units for selected elements, magnesium (Mg), potassium (K), rubidium (Rb), strontium (Sr) and cesium (Cs) are summarized in Table 1 below.

Table 1. Ranges of analyses for selected alkalis on the Concessions
Li ppm K % Rb ppm Cs ppm Mg % Sr ppm
Upper Clay 41 - 6,200 0.12 - 1.75 23 - 480 34 - 1,805 0.13 - 5.21 128 - 8,380
Lower Clay 38 - >10,000 0.12 - 4.45 14 - 880 68 - 3,000 0.16 - 5.52 31 - 6,820

The lower clay unit shows significant enrichment in alkali metals in comparison to the upper clay unit.

Based on the intervals used to estimate inferred lithium resources for the Concessions (which have been declared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") (for a discussion of such resources, please refer to the Company's news release dated August 28, 2013)) at varying Li cutoffs, new inferred resources for selected alkalis have been estimated for those same intervals based on the Li cut-offs. These new inferred resources for selected alkalis are tabulated below (Table 2). Further testing will be necessary to confirm economic feasibility of recovering these elements as either co-products or by-products in a potential future mining and processing operation. The Company plans to initiate further metallurgical testing to determine if these elements are recoverable. In accordance with NI 43-101, the Company will prepare a technical report in respect of this initial inferred resource estimate, which will be filed on SEDAR within 45 days from today.

2 It should be noted that figures expressed above are gross figures. The Concessions are the subject of a joint venture between the Company and REM, pursuant to which REM has an option to earn up to a 49.9% interest. To date, REM has earned a 30% interest.

Martin Vidal, President of Bacanora, commented: "We are very pleased to be able to report the elevated values in the other alkalis on the El Sauz and Fleur concessions as this implies further additional economic potential for the project if recoveries of these elements can be achieved. The Company looks forward to advancing efforts to recover additional alkali compounds along with lithium carbonate."

About the Sonora Lithium Project:

The Sonora Lithium Project consists of the La Ventana, La Ventana 1 and the San Gabriel concessions which are owned 100% by Bacanora along with the contiguous El Sauz, El Sauz 1, El Sauz 2, Fleur and Fleur 1 concessions owned 70% by Bacanora and 30% by REM. The Company has declared inferred resources on each of the La Ventana concessions and the Bacanora / REM Joint Venture Lands, in respect of which reports have been prepared in accordance with NI 43-101 (please refer to the Company's SEDAR filings for copies of these reports and related press releases). Inferred resources have been estimated for the La Ventana Lithium Deposit totaling 60 million tonnes averaging 3,000 ppm Li (equivalent to 1.6% lithium carbonate equivalent(3) assuming 100% recovery and no process losses). Inferred resources for the El Sauz and Fleur concessions total 88,271,000 tonnes averaging 3,163 ppm Li at a 2,000 ppm cut-off (1.68% lithium carbonate equivalent assuming 100% recovery and no process losses). The resource on the Bacanora/REM Joint Venture Lands is open down dip to the east and to the south. For further details concerning the Company's agreement with REM and details of the joint venture, please refer to the Company's press release dated May 22, 2013.
