GB Minerals Ltd. Announces Proposed C$3,732,000 Private Placement

VANCOUVER, BC / ACCESSWIRE / March 7, 2016 / GB Minerals Ltd. (TSXV: GBL) (the "Company") is pleased to announce a non-brokered private placement of 67,854,547 new common shares (the "Placement Shares") in the share capital of the Company (the "Share Capital"), at a price of C$0.055 per Placement Share for gross proceeds of C$3,732,000 (the "Placement").

A.B. Aterra Resources Ltd. which taken together with its related companies (together, "Aterra") is an existing significant shareholder of the Company and an insider within the meaning of the rules of the TSX Venture Exchange (the "TSXV"), is proposing to subscribe for 12,285,455 Placement Shares and will, upon completion of the Placement, own an aggregate of 225,749,097 common shares of the Company representing 46.47% of the Share Capital.

The Placement Shares will represent an increase of approximately 14% in the enlarged Share Capital and approximately 13.2% of the fully diluted enlarged Share Capital. The Placement Shares will be subject to a four-month hold period from the date of issuance. Application will be made for the listing of the Placement Shares on the TSXV. Closing of the Placement is subject to due diligence by investors and the receipt of applicable regulatory approvals, including the approval of the TSXV.

The Company intends to use the net proceeds from the Placement for expenses and development of the Company's Farim phosphate mineral property, to meet the Company's financial obligations and operational commitments and to fund litigation involving GBM Minerals Engineering Consultants Limited.

Aterra is a "related party" to the Company under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101") by virtue of its existing shareholding being in excess of 10% of the Share Capital. Accordingly, the Placement is a "related party transaction" under MI 61-101. The Placement is exempt from (i) the formal valuation requirements under Section 5.4 of MI 61-101 pursuant to Subsections 5.5(g) of MI 61-101 and (ii) the minority approval requirements under Section 5.6 of MI 61-101 pursuant to Subsection 5.7(1)(e) of MI 61-101because the board of directors of the Company, acting in good faith, has determined, and at least two-thirds of the Company's independent directors, acting in good faith, have determined, that the Company is in serious financial difficulty, that the Placement is designed to improve the Company's financial position and that the terms of the Placement are reasonable in the Company's circumstances.

The Company anticipates it will file a material change report less than 21 days before the closing of the Placement. This shorter period is reasonable and necessary in the circumstances as the Company required the proceeds of the Placement immediately.

Luis da Silva, President and Chief Executive Officer of the Company, comments:

"Following the recent capital restructuring, this latest private placement is a demonstration of our continuous efforts to raise financing and we are extremely pleased to have a new institutional investor such as JP Morgan Asset Management UK Limited. This diversification of the shareholder register along with further support from existing shareholders should strengthen the Company's position as we prepare to raise the development finance that is sought for Farim."

ABOUT GB MINERALS LTD.

On September 14, 2015, the Company announced the results of, and filing on SEDAR, of a new feasibility study on its Farim phosphate project entitled "NI 43-101 Technical Report On the Farim Phosphate Project" (the "2015 Feasibility Study").

The Farim phosphate project is located in the northern part of central Guinea-Bissau, West Africa, approximately 25 kilometres south of the Senegal border, approximately 5 kilometres west of the town of Farim and some 120 kilometres northeast of Bissau, the capital of Guinea-Bissau, on a 30.6 km2 mining lease license granted by the Government of Guinea-Bissau to the Company's wholly owned subsidiary, GB Minerals AG, in May 2009. The Company also holds a production license in relation to the Farim phosphate project.

The Farim phosphate project consists of a high grade sedimentary phosphate deposit of one continuous phosphate bed which extends over a known surface area of approximately 40 km2. It is estimated to contain measured and indicated resources of 105.6 million dry tonnes at a grade of 28.4% P2O5 and additional inferred resources of 37.6 million dry tonnes at 27.7% P2O5. The measured and indicated resources include 44.0 million dry tonnes of reserves based on a 25 year mine plan at 1.75 million tonnes per annum ("mtpa") of mine production at the following run of mine grades: 30.0% P2O5, 2.6% Al2O3, 41.0% CaO, 4.7% Fe2O3, and 10.6% SiO2. The phosphate ore will be beneficiated for a final phosphate rock concentrate production of 1.32 mtpa at a 34.0% P2O5 grade at 3% moisture.

The 25 year mine plan also assumes a beneficiation process that involves scrubbing (both drum and attrition) followed by particle sizing to remove the fraction under 20 µm. This new beneficiation process will result in a 34.0% P2O5 product grade, mass recovery of 75.5% and 78.4% P2O5 recovery confirmed by a pilot scale test on a one tonne sample that took place in May 2015. After passing through the process plant, the final production of phosphate concentrate, based on 1.75 mtpa of run of mine feed, will be 1.32 mtpa. The life of mine operating costs are approximately US$52.13 per tonne of final concentrate. The initial capital cost for the project is estimated at US$193.8 million and does not include owner's costs which amount to US$11 million and include items such as project insurance, resettlement and owner's team costs. Owner's costs have been included in the financial analysis.

FORWARD LOOKING STATEMENTS

Certain information in this news release relating to the Company is forward-looking and related to anticipated events and strategies. When used in this context, words such as "will", "anticipate", "believe", "plan", "intend", "target" and "expect" or similar words suggest future outcomes. Forward-looking information contained in this press release includes, but may not be limited to the amount of proceeds raised by the Placement, the Placement and the closing of the Placement, the use of proceeds and the business plans, statements or information relating to the anticipated development activities of the Company, the Farim Project (including the quantity and quality of mineral resource and mineral reserve estimates), the potential to upgrade inferred mineral resources, the ability of the Company to develop the Farim Project into a commercially viable mine and the proposed new plans relating thereto regarding operations and mine design, estimates relating to tonnage, grades, recovery rates, future phosphate production, future cash flows, life of mine estimates, expectations regarding production and estimates of capital and operating costs. By their nature, such statements are subject to significant risks and uncertainties that may cause actual results or events to differ materially from current expectations. Readers are cautioned not to place undue reliance on forward-looking information as actual results could differ materially from the plans, expectations, estimates or intentions expressed in the forward-looking information. Forward-looking information speaks only as of the date on which it is made and, except as may be required by applicable law, the Company disclaims any obligation to update or modify such forward-looking information, either as a result of new information, future events or for any other reason.

Disclosure herein of exploration information and of mineral resources and mineral reserves is derived from the 2015 Feasibility Study. Information relating to "mineral resources" and "mineral reserves" is deemed to be forward-looking information as it involves the implied assessment based on certain estimates and assumptions that the mineral resources and mineral reserves can be profitable in the future. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. By their nature, mineral resource and mineral reserve estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. If such estimates are inaccurate or are reduced in the future, this could have a material adverse impact on the Company. Accordingly, readers should not place undue reliance on forward-looking information. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Due to the uncertainty that may be attached to inferred mineral resources, it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration.

NEITHER THE TSX VENTURE EXCHANGE NOR ITS REGULATION SERVICES PROVIDER (AS THAT TERM IS DEFINED IN THE POLICIES OF THE TSX VENTURE EXCHANGE) ACCEPTS RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS RELEASE
