PCP GB Minerals Ltd.

VANCOUVER, July 30, 2012 /CNW/ - Plains Creek Phosphate Corporation ("Plains Creek", the "Company") (TSX‐V: PCP) is pleased to announce the results of a Preliminary Economic Assessment ("PEA") for the Direct Shipping Option ("DSO") Project, the first step in the development of the GB Minerals AG Farim Phosphate Project located in Guinea Bissau, West Africa. The PEA was prepared by GBM Minerals Engineering Consultants Limited ("GBMMEC") in conjunction with Golder Associates Limited ("Golder"), GEEEM Consultants and Tropica Environmental, all of whom are independent of the Company. Summary of the DSO Project PEA The Farim Phosphate Project consists of a high grade sedimentary phosphate deposit of one continuous phosphate bed, known as the FPA layer, which extends over a known surface area of approximately 40 km². A Measured and Indicated Resource of 32.60 million tonnes ("Mt") of DSO phosphate has been identified within the Farim Phosphate Project for the DSO Project with a P(2)O(5) grade in excess of 30.7 % and an average R(2)O(3) content of 6.01%. A 25 year mine life is planned for a total of 12.5 Mt of DSO phosphate (500,000 tonnes per annum), at an average grade of 30.7% P(2)O(5) and less than 6% R(2)O(3). Based on the current Measured and Indicated Resources the potential mine life for the DSO Project can be extended to in excess of 50 years at this production rate, based on the model and assumptions contained in the PEA. The average strip ratio over the 25 year mine plan is 7.4:1 (bank cubic meters waste: tonne phosphate).  The average thickness of phosphate deposit is approximately 4 meters over the life of the DSO Project. Average annual waste production is 3.6 Mm(3).  The mine plan grade has been optimized to remain above 30% P(2)O(5) for each of the 25 years of mine life. The current financial model assumes the mining of 12.5 million tonnes which is less than 38% of the recently announced Indicated and Measured DSO Resources. There is also potential to improve the Project economics by increasing the production rate and the life of mine, capital and working costs. The Farim Phosphate Project has been granted a Mining Lease and a Production License by the Guinea-Bissau Government. This is valuable to optimizing the timetable for development and production. The DSO Project encompasses the following general process flow: -- Contractor mining; -- Removal of overburden by a combination of excavators and trucks; -- Run of Mine("ROM") phosphate removed by excavators and trucks and stockpiled for loading and blending close to a barge loading system located some 1.5 km from the open pit mine; -- A number of barges moored to a floating pontoon will be loaded and taken to a bulk carrier vessel (of 25,000 tonnes capacity) moored to a floating ship loading facility off the Rio Casheu estuary for dispatch to customers and off takers; -- The river transport distance from the planned barge loading site at the mine site to the Rio Cacheu estuary ship loading facility on the Atlantic Ocean is approximately 150 kilometres; and -- ROM phosphate will also be available for supply to the in-country market as a direct application fertilizer.

Key Assumptions and Methods Golder prepared the Resource Estimate by modeling the Farim resource based on a two dimensional (2D) block model with 125 m x 125 m cells and 25 internal discrete nodes covering the extents of the FPA layer. The extents of the FPA layer were estimated based on the presence or absence of the FPA layer in the drill holes. Exploratory data analysis and variography were carried out and variables were estimated using a three pass strategy, whereby each successive pass had an increased search radius and less restrictive sample selection criteria. This approach ensures all blocks received a value for each variable. Values were assigned using a combination of Ordinary Kriging and Inverse Distance Weighted methods for the following variables: P(2)O(5); Al(2)O(3); CaO; Fe(2)O(3); SiO(2); FPA Thickness; and Overburden Thickness. The stripping ratio was derived from the estimated overburden and FPA thicknesses. Classification was assigned to each block in the model based on a drilling spacing as follows: -- Measured Resource: Areas with drilling coverage of up to 500 m by 500 m and a P₂O₅ slope of regression greater or equal 0.65; -- Indicated Resource: Areas with drilling coverage of up to 1000 m by 1000 m and a P₂O₅ slope of regression greater or equal 0.4; and -- Inferred Resource: Areas within the extents of the FPA and not classified as Measured or Indicated. A corridor following the Rio Cacheu was excluded and set to "unclassified" due to the uncertainty related to the extraction of material in this area. In addition, the resource estimate was divided into blocks corresponding to the location relative to the Rio Cacheu; "north" or "south". After applying the above criteria and the for the purpose of public reporting the resources where restricted to a minimum FPA thickness of 1.5 m and a stripping ratio no greater than 20:1. By applying these mining restrictions it is considered that the disclosed mineral resource estimates fulfill the requirement of "reasonable prospects for economic extraction". Due to the consistent grade continuity, with grades above 27% P₂O₅ , a phosphate cut-off grade was not applied to report the Mineral Resource estimates. Data Verification Data verification was carried out by Golder and included independent sampling, a core logging check, drill hole collar survey checks and database integrity checks. No material issues were noted. Golder reviewed the quality assurance and quality control (QAQC) procedures reported from previous exploration campaigns.  QAQC procedures and data from GB Minerals AG (which is the subsidiary of the Company that holds the title to Farim Phosphate Project) were reviewed by Golder. GB Minerals AG submitted a total of eight field duplicates and six standards samples in a total of 156 samples. No blanks were submitted. There is no process design involved in the direct shipping of phosphate by sea transportation.  During a site visit in May 2011, Golder reviewed the drilling, logging and sampling procedures employed by GB Minerals AG. A laboratory audit of both the sample preparation and assaying facilities was also carried out by Golder. Data verification for resources was also extensively covered in the previously filed Technical Report of the Company dated February 10, 2011 filed on SEDAR under the Company's profile at www.sedar.com. Mining The majority of the annual rainfall over the DSO Project area is concentrated in the period from July through September, and the DSO Project mine plan will carry out mining activities for 10 months out of the year to avoid the inefficiencies of mining during the higher rainfall months.  Installed mining equipment capacity has been designed to produce the annual plan phosphate requirements and associated waste stripping within the 10 drier months of the year. Key design elements of the DSO mining plan are water management and haul road maintenance.  All mining areas must be fully dewatered in advance of mining activities. The proximity of the mine to the Rio Cacheu will require the construction of a protection dyke to prevent in-pit flooding. Contractor mining has been selected, for the excavator / truck mining method for the DSO mining plan based on flexibility, lower initial capital, lower investment risk, grade control, and the ability to blend quality for required product specifications. Contractor mining has been proposed to minimize capital investment and to shorten the period to production which could arise from the availability of mining capital equipment and the shortage of in country manpower skills. The remote nature of the Project, with limited power supply, precludes the use of electric mining equipment and all mining equipment selected for the DSO Project is diesel mobile equipment. This mining method uses excavators and trucks to handle 100% of the overburden and DSO phosphate. Waste will be stripped and removed with 11 m(3 )to 12 m(3) bucket front-end loaders or small hydraulic excavators matched with 50 ton haul trucks.  The DSO phosphate will be mined with 3 m(3 )to 4 m(3 )bucket class backhoes matched with 35 t trucks. ROM phosphate will be removed by excavators and trucks to a 20,000 tonne ROM pad for storage and blending. The ROM pad is located some 1.5km from the open pit and adjacent to the barge loading facility. The DSO operation will mine 0.5 Mtpa of phosphate and will require a waste storage facility capable of holding 34 Mm(3).  The facility will be approximately 25 m high with a footprint of 1000 meters by 1500 meters. Beneficiation The ROM phosphate will be mined, blended if necessary and will be directly shipped with limited treatment or processing (if any). Project Infrastructure and Product The infrastructure requirements associated with the DSO project include the mine infrastructure, mine camp, offices, workshops, water treatment facilities, power generation and water supply. River Transport and Loading Transfer of phosphate from the ROM pad to the feed hopper of the barge loading facility will be by front end loader. The hopper will feed a conveyor system to load 2,700 t non-propelled barges. Sets of barges will then transport with the aid of a pusher tug down the Rio Cacheu to a seagoing vessel. The barges will be unloaded by the seagoing vessel anchored to a floating ship loading facility beyond the shallow waters (+ 12 meter deep) using clam shell unloaders.  Possible mooring points accessible to vessels of capacity up to 25,000t have been identified in the estuary of the Rio Cacheu. Recommendations The results of the Preliminary Economic Assessment show that the DSO Project is robust from a technical and economic standpoint at the selected long term phosphate prices, and GBMMEC has recommended that the DSO Project continues to be advanced to the Feasibility Stage and that a production rate of 1 Mt per annum be investigated.
