Operational performance at the Karowe Mine was better than forecast for H1 2016.
Safety performance was excellent with zero LTIs reported, and all other SHECR indices within target.
Both ore and waste tonnage mined was ahead of forecast for both for second quarter and year to date. Ore mining remains concentrated in the South lobe. The process plant has performed well during the second quarter and year to date with tonnes processed ahead of forecast and carats recovered in line with expectation. For the first six months of 2016, Karowe has recovered 340 special stones (+10.8 carats) including 12 stones over 100 carats.
The project to increase the top size of diamonds recoverable by the existing Large Diamond Recovery circuit is well advanced with specialized equipment in fabrication and commissioning on track for end of Q3 2016. The Mega Diamond Recovery project is on schedule and currently in detailed design stage with procurement of long lead items complete.
EXPLORATION AND MOTHAE
Botswana Prospecting Licenses
In 2014, the Company was awarded two precious stone prospecting licenses (PL367/2014 and PL371/2014), which are known to host kimberlites, BK02, AK11 and AK12, AK13 and AK14. The prospecting licenses are located within a distance of 15 km and 30 km from the Karowe Diamond mine. Ground geophysical surveys were conducted over the known kimberlite occurrences within the prospecting licenses during Q4 2014, Q1 2015 and Q2 2016. The geophysical results confirmed the kimberlite localities and have provided information that has been used to plan our core drilling and surface sampling programs. A drill programme will be initiated during Q3 2016 at BK02, AK11, AK13, and AK14.
In Q2 2016, the Company completed processing of the BK02 sample (see announcement dated June 13, 2016). The results of the BK02 bulk sample were press released on June 13, 2016. A total of 274.33 carats were recovered from the processing of 5,916 tonnes of BK02 material, for a sample grade of 4.6 cpht (carats per hundred tonne). The largest diamond recovered was a 5.48 carat brownish octahedron, in addition a total of 24 stones were recovered greater than 1 carat in weight, including 3 diamonds in excess of 2 carats in weight. Additional sampling will take place at BK02 and processing of the additional material from BK02 will start in mid Q3 2016.
Surface sampling of AK12 was completed and processing was initiated during Q2. Subsequent to the end of Q2 2016, processing of 2,550 tonnes of the AK12 sample had been completed with diamond recoveries of less than 0.5 cpht recovered. The AK12 sample showed no possibility of economic return and the sample processing was terminated after 43% of stockpiled sample had been processed. Environmental approvals for drilling campaigns on the Prospecting Licenses were received from Republic of Botswana Department of Environment Affairs ("DEA").
Karowe Resource Upgrade Drilling
Drilling commenced on a planned 10,000 metre deep drill programme designed to test the AK06 kimberlite at depths below 400m with the a target to bring inferred mineral resources into the indicated category in support of underground mining studies. Drilling commenced in the latter stages of Q2 2016 and is ongoing with three core drilling rigs active.
Mothae Diamond Project, Lesotho
On March 31, 2016, the Company completed the transfer of its shares of Mothae Diamonds Pty Ltd and the Mothae site bulk sample plant to the Government of Lesotho. As consideration, the Government of Lesotho has released the Company from all liabilities relating to the rehabilitation of the Mothae Diamond Project. Lucara has no remaining ownership in this project.
2016 OUTLOOK
These are "forward-looking statements" and subject to the cautionary note regarding the risks associated with forward-looking statements.
Karowe Mine, Botswana
Operating guidance:
The Company continues to forecast revenue between $200 million and $220 million for the year ending December 31, 2016, excluding the sale of the Constellation, which sold for $63.1 million. The Company continues to hold the Lesedi La Rona in inventory as at June 30, 2016 and is currently considering options for its sale.
Karowe's operating cash costs guidance has been decreased for the year from between $33.50 to $36.50 per tonne of ore processed to $29.0 to $31.0 per tonne ore processed. The reduction in cost guidance is due to the depreciation of the Pula compared to the US dollar, power and general cost savings. The mine continues to forecast between 2.2 to 2.4 million tonnes of ore processed, producing over 350,000 carats of diamonds in 2016.
Ore mined for the quarter is in line with previous guidance of between 3.0 and 3.5 million tonnes and waste mined is expected to be between 13.0 and 14.0 million tonnes.
Capital and exploration guidance:
The Company continues to be forecast between $15 million and $18 million for the modifications to the existing Large Diamond Recovery ("LDR") circuit and the installation of a Mega Diamond recovery ("MDR") circuit. The Company's $11 million guidance for 2016's sustaining capital expenditure, which includes a mill re-liner at a cost of $1.5 million and an investment of $1.5 million for a combined sales and administrative office in Gaborone, remains unchanged.
The Company maintains its forecast to spend approximately $3.7 million for deep drilling in the south lobe of the AK6 kimberlite, with the goal of converting inferred resources below 400 metres depth to an indicated resource. An exploration budget of up to $7.0 million is maintained for advanced bulk sampling and drilling work at the Company's two Botswana prospecting licenses.
The USD/Pula guidance foreign exchange rate is 10. The USD/Pula foreign exchange rate for H1 was 11.1.
