Interim Management Statement and Q3 FY 2014 Production and Sales Report

Petra Diamonds Limited announces its Interim Management Statement ("IMS") for the period from 1 January 2014 to 22 April 2014, covering production and sales from 1 January 2014 to 31 March 2014 ("Q3", "Q3 FY 2014" or the "Period").

HIGHLIGHTS

· Production for Q3 FY 2014 up 15% to 743,424 carats (Q3 FY 2013: 647,248 carats).

· Production for nine months to 31 March 2014 up 26% to 2,379,140 carats (nine months to 31 March 2013: 1,894,767 carats).

· Petra firmly on track to meet FY 2014 production target of ca 3.0 million carats.

· Revenue for Q3 FY 2014 up 55% to US$163.9 million (Q3 FY 2013: US$105.7 million), including the 29.6 carat blue diamond which sold for US$25.6 million.

· Revenue is weighted towards the second half of the financial year ("H2") due to the usual seasonal timing of Petra's diamond sales; two more tenders are to take place between the date of this IMS and financial year-end.

· A strong start to the calendar year for the rough diamond market, with prices achieved by Petra up around 10%; Petra expects the market to consolidate around current price levels for the remainder of FY 2014.

COMMENTARY

Production

· Q3 production was up 15% to 743,424 carats (Q3 FY 2013: 647,248), primarily due to the strong run rate and increased contribution from Finsch. This Group result was achieved despite the higher than average rainfall during the Period in South Africa, which particularly impacted on ore treatment at both Finsch and Cullinan, and in Tanzania, which impacted on production at Williamson.

· Finsch recorded another strong quarter, with diamond production increasing 34% to 460,144 carats (Q3 FY 2013: 343,988). ROM tonnes were up 15% on Q3 FY 2013 despite the fact that underground production was impacted by wet ground conditions due to the aforementioned unseasonably high rainfall. The estimated ROM grade (see comment below) was in line with expectations, following the changes to the plant bottom cut as previously announced.

· Finsch's tailings grade is estimated to have increased to 33.5 cpht (Q3 FY 2013: 20.9 cpht). It should be noted that the Company is not able to exactly measure the ROM / tailings grade split, as ore from both sources is processed through the same plant.

· Cullinan's ROM grade of 24.9 cpht (Q3 FY 2013: 29.5 cpht) was below management expectations, although year to date ("YTD") the ROM grade of 29.0 cpht remained in line with the comparative nine month period in FY 2013. The ROM grade achieved for April so far has recorded an improvement on the Q3 grade to ca. 29 cpht.

· As previously communicated, Petra is currently operating in highly diluted production areas at Cullinan, which will result in ROM grade volatility until the expansion programme opens up undiluted ore from the new C-Cut block cave. Plant efficiency is also affected by the C-Cut development work, as increased tonnages of development waste are included in the same treatment circuit as ore from the production areas.

· Petra has a number of initiatives in place to mitigate the diluted ROM grade at Cullinan, which have recently included the identification of high-waste draw points in the higher grade BB1 East, with the draw plan therefore modified accordingly to target draw points with a higher kimberlite content. ROM grades are expected to remain variable until FY 2016, when the C-Cut expansion programme provides access to the new block of undiluted ore, and management remains highly focused on managing this issue.

· Cullinan's tailings production increased by 52% to 28,728 carats (Q3 FY 2013: 18,955 carats). Tailing tonnes treated for FY 2014 will fall short of original guidance of ca. 2.7 Mt, with plant operations being affected by Eskom power interruptions.

· At Koffiefontein, the positive trend on carat production continued. Q4 FY 2014 ROM production is expected to increase to ca. 90,000 ROM tonnes treated, with ca. 40,000 ROM tonnes mined and stockpiled during Q3 to be processed. The treatment of recovery tailings, supplemented by ore from the Ebenhaezar satellite pit, delivered 8,479 carats (Q3 FY 2013: 4,337 carats) at a grade of 11.3 cpht (Q3 FY 2013: 1.5 cpht).

· At Kimberley Underground, ROM tonnes further increased to 237,323 tonnes (Q3 FY 2013: 182,211). Although the rate of ramp-up is less than originally planned, a further improvement in throughput is expected in Q4 FY 2014. Recovered grades were marginally below management's earlier expectations with the depletion of the Joint Shaft stockpile during the Period. The remaining Wesselton stockpile contains ca. 300,000 tonnes for future processing.

· At Williamson, ROM tonnes increased by 18% over the comparative period, continuing the upward trend. ROM grades reduced by 7%, due to the excessive rainfall during Q3 which led to higher grade production areas being made inaccessible, while power interruptions and plant modifications in process impacted plant performance. Q4 FY 2014 throughput is expected to reach ca 900,000 tonnes, giving an annualised equivalent production level of 3.6 Mtpa.

· At Helam, a business review process has commenced and further information will follow when Petra publishes its FY 2015 guidance update in August 2014.

Diamond market and sales

· The rough diamond market had a strong start to the calendar year and remained firm throughout the Period, with prices achieved by Petra up around 10%; Petra expects the market to consolidate around these price levels for the remainder of the financial year.

· Revenue for Q3 was up 55% to US$163.9 million (Q3 FY 2013: US$105.7 million).

· Carats sold were up 36% to 905,781 carats (Q3 FY 2013: 668,193).

· Petra sold seven 'special' stones exceeding US$1 million each during Q3 (five from Cullinan and two from Koffiefontein) for total revenue of US$39.9 million, including the 29.6ct blue for Cullinan which, as previously reported, sold for US$25.6 million.

· Two tenders took place during the Period and, as usual, revenue is weighted towards the full H2 period, with two more tenders to take place between the date of this IMS and financial year-end.

· The table below sets out the average diamond prices achieved for Q3 by mine against comparative periods and original FY 2013 guidance. Prices achieved year to date are in line with or, in some instances, above guidance.

Notes:

1. All sales (both ROM and tailings) including 'specials' (stones above US$1 million in value) were used to calculate the above average values.

2. Cullinan's Q3 average value included the 29.6 carat blue diamond that sold for US$25.6 million; excluding this stone, the average value was US$164/ct.

3. Cullinan's H1 average value included the 126.4 carat diamond that sold for US$8.5 million; excluding this stone, the average value was US$129/ct.

4. Cullinan's nine months to 31 March 2014 average value included the two 'special' stones mentioned in Notes 2 and 3 above; excluding these stones, the average value was US$143 per carat.

Financial

· As at 31 March 2014, Petra had cash at bank of US$29.7 million (31 March 2013: US$35.3 million), diamond debtors of US$64.9 million (31 March 2013: US$5.5 million) (increase in debtors due to timing of March 2014 tender) and diamond inventories of circa US$35 million (404,210 carats) (31 March 2013: US$40 million, 380,294 carats) (lower value mainly attributable to weakening of the ZAR against the US$).

· Loans and borrowings as at 31 March 2014 were US$155.0 million (31 March 2013: US$122.9 million), comprising bank loans and borrowings of US$147.7 million (31 March 2013: US$122.4 million) and utilisation of US$7.3 million (31 March 2013: US$0.5 million) of foreign exchange settlement lines.

· Net debt as at 31 March 2014 of US$118.0 million (31 March 2013: US$87.1 million), (excluding foreign exchange settlement lines) is in line with expectations, and capital expansion plans remain fully funded; debt facilities (including the foreign exchange settlement lines) undrawn and available to the Group as at 31 March 2014 of US$57.0 million (31 March 2013: US$110.8 million).

Health and safety

· Group lost time injury rate ("LTIFR") for Q3 improved to 0.39 (Q3 FY 2013: 0.43).

· Health and safety remains the number one priority for Petra and all of the Company's efforts and initiatives in this regard strive for a zero harm workplace.

Notes:

1. Exchange rates of R10.5225/US$1 as at 31 March 2014 and R9.2251/US$1 as at 31 March 2013 have been used for the purposes of this announcement.
