Anooraq Reports Results Of Lebowa Technical Review
April 14, 2008, Vancouver, BC ― Anooraq Resources Corporation (“Anooraq” or the “Company”) (TSXV: ARQ; AMEX: ANO; JSE: ARQ) is pleased to announce the completion and results of the technical review of Lebowa Platinum Mines (“Lebowa”) which was undertaken as part of the due diligence associated with a transaction with Anglo Platinum Limited (“Anglo Platinum”) (see September 4, 2007 news release).
Pursuant to the preliminary transaction agreements announced in September 2007, Anglo Platinum will sell to Anooraq an effective 51% of Lebowa (currently 100% owned by Anglo Platinum), and an additional 1% interest in each of the advanced exploration stage Ga-Phasha Platinum Group Metals (“PGM”) Project (“Ga-Phasha”), Boikgantsho PGM Project (“Boikgantsho”) and the early stage Kwanda PGM Project (“Kwanda”). Anooraq currently holds interests in Ga-Phasha, Boikgantsho, and Kwanda, by way of 50/50 joint ventures with Anglo Platinum and so would increase its interests in each of these projects from 50% to 51%. All of these projects are located in the Bushveld Complex of South Africa. Upon completion of the Lebowa transaction, it is expected that Anooraq will control the 3rd largest PGM resource base in South Africa.
Lebowa Operations & Growth Plan
-
Lebowa is an operating mine located on the North-Eastern limb of the Bushveld Complex, to the north of and adjacent to Ga-Phasha.
-
Lebowa consists of a vertical shaft and a decline shaft system to access the underground development on the Merensky (~85,000 tonnes per month [“tpm”]) and UG2 Reefs (~45,000 tpm), as well as two concentrator plants.
-
Production at Lebowa in 20071 was approximately 187,700 refined ounces of platinum, palladium, rhodium and gold (“4E”) from 1.33 million tonnes (“Mt”) of ore milled.
- Anglo Platinum has approved a long term growth plan for Lebowa, which includes various replacement and expansion projects. Anooraq, as a controlling shareholder, supports this growth plan which will result in existing mining operations at Lebowa increasing in two stages. Technical studies conducted by Anglo Platinum indicate that Lebowa’s value is maximized at a mining rate of 375,000 tpm, comprising steady state Merensky production at 120,000 tpm and steady state UG2 production of 255,000 tpm.
- o Stage 1 (2008-2013) comprises an expansion of Merensky and UG2 ore production to 245,000 tpm, with Merensky production being increased to 120,000 tpm, initially from the Brakfontein Merensky decline shaft system and UG2 production being increased to 125,000 tpm, initially from the Middelpunt Hill UG2 decline shaft system.
- o Stage 2 (2016 onwards) sees the further expansion of UG2 production to 255,000 tpm with Merensky production remaining at 120,000 tpm.
Anooraq engaged international mining industry consultants to conduct a technical review of the Lebowa mine. The Mineral Resources and Mineral Reserves have been reviewed by Snowden Mining Industry Consultants (“Snowden”). A technical report by independent qualified persons D.B. Gray, Pr.Sci.Nat., and B.C. Rip, Pr.Eng., FSAIMM, has been filed on www.sedar.com. The aforementioned qualified persons have reviewed and approved the technical disclosure in this news release.
This technical review indicates 11.2 million ounces (Moz) of platinum, palladium, rhodium and gold (4E) in estimated Mineral Reserves at December 2007, which represents a 7.7% increase in the overall estimated Mineral Reserves within approved project areas, compared to the estimated Mineral Reserves of 10.4 Moz disclosed in the September 4, 2007 news release. The increase in Mineral Reserves is attributable to Lebowa’s ongoing drilling and development program.
The technical review confirmed the following Mineral Reserves and Resources.

Notes: The Mineral Reserves stated are for 100% of Lebowa. Anooraq’s interest would be 51% of the above Mineral Reserves once the transaction is completed.
Mineral Reserves are exclusive of Mineral Resources.
Tonnes and ounces have been rounded and this may have resulted in minor discrepancies.
The 4E elements are the sum of platinum (Pt) + palladium (Pd) + rhodium (Rh) + gold (Au).
Only Measured and Indicated Resources have been converted to Mineral Reserves.
Mineral Reserves have been determined by applying modifying factors to the Mineral Resource.
Mineral Reserves are as at December 31 2007 and will have been depleted by current mining since December 2007.
The Merensky pay limit (break even) varies between 1.3 and 4.8 g/t 4E across all operations of Anglo Platinum.
The UG2 pay limit (break even) varies between 1.3 and 4.4 g/t 4E across all operations of Anglo Platinum.
Contained metal in reserve table has recoveries applied.

Notes: The Mineral Resources stated are for 100% of Lebowa. Anooraq’s interest would be 51% of the above Mineral Resources once the transaction is completed.
Mineral Resources are exclusive of Mineral Reserves.
Tonnes and ounces have been rounded and this may have resulted in minor discrepancies.
The 4E elements are platinum (Pt) + palladium (Pd) + rhodium (Rh) + gold (Au).
Oxidised zones and all geological losses have been excluded from the resources.
Mineral Resources that are not Mineral Reserves have potential economic viability but have not yet been demonstrated by an approved mining plan. Measured and Indicated Mineral Resources are generally located within 650 m depth from surface.
Inferred Mineral Resources are generally located beyond 650 m depth from surface.
Cut-off grades of 2.4 to 3.5 g/t 4E depending on reef characteristics are applied to Merensky Mineral Resource statements.
A cut-off grade of 1.8 g/t 4E is applied to UG2 Mineral Resource statements.
No recoveries are applied for contained metal in the resource table.
Approach of the technical review
Relevant geological information, the interpretation thereof and the estimation methodology have been reviewed by Snowden.
The reserve estimate takes into consideration all geologic, mining, milling, and economic factors. Mineral Reserves and Resources are stated according to SAMREC 2007 (South African Code for Reporting of Mineral Resources and Mineral Reserves) and also comply with Canadian standards (NI 43-101). The capital and operating costs stated are estimated to a 90% level of accuracy for approved projects.
The economic analysis undertaken for the technical review used South African Rand (“ZAR”) as the base currency and takes into consideration relevant taxes and royalties. Royalties are based on the rates prescribed in the third draft of the proposed Royalty Bill. The resultant effective royalty is 5.4% of revenue.
The technical review used projected metal prices based on analyst consensus estimates to 2012 resulting in the following average price forecast over the next five years:

The nominal exchange rates for the first five years are based upon consensus analyst forecasts. Thereafter the ZAR is estimated to depreciate by 1.07% per annum, which is the difference between estimated South African Consumer Price Index (SA CPI) of 3.8% and estimated US CPI of 2.7%. The real assumptions have been derived from the inflation assumptions presented below.

Certain Indicated and Measured Mineral Resources have been demonstrated to have economic viability, albeit at a lower level of confidence through pre-feasibility studies by Anglo Platinum and have been used in the economic evaluation of Lebowa, in proposed (not approved) projects. An additional 51.9 Mt grading at 4.49 4E g/t have been converted from the Mineral Resources to Proven and Probable Mineral Reserves in the proposed project evaluations.

Sensitivity analysis
Sensitivity analyses were done as part of the technical review. Results in ZAR and Canadian dollars (“CAD”) are summarized in the tables below. The analyses show that the project is most sensitive to revenue followed by operating cost and the totals show changes in real LOM operating cost, real LOM basket price and NPV for the Lebowa mine.
