Gross profit ($’m)2	5.6	4.0	11.7	8.6	Lower gross profit due to fewer ounces sold, lower gold price and higher on-mine costs
Net profit attributable to shareholders ($’m)	1.8	0.3	4.3	1.9	Net profit in Q2 of 2015 is after losses on discontinued operations in Zambia
Adjusted basic earnings per share3 (cents)	3.7	2.3	7.8	5.2	Adjusted eps excludes foreign exchange profits and losses, deferred tax and the expenses of the Zambian office which has now been closed

Commenting on these results, Steve Curtis, Caledonia’s President and Chief Executive Officer said:

“2015 is a very important year for Caledonia as we continue to implement the Revised Investment Plan, which we presented to investors in November last year. We are currently sinking, deepening or equipping four shafts at the Blanket mine in Zimbabwe and I expect this activity will translate into increased production from the first quarter of 2016.

“Caledonia’s board and management believe that the implementation of the Revised Investment Plan remains in the best interests of shareholders: the successful implementation of the plan will result in a significant increase in Blanket’s production and operating efficiency; the lower gold price increases the importance of delivering the Revised Investment Plan as scheduled. I am pleased to report that we have met all of our key milestones and we remain on target for achieving all of the future milestones.

“We have sharpened our focus on our core operation and we are streamlining our corporate structure by terminating dormant companies and non-core assets. Operationally, the management team is focused on implementing the Revised Investment Plan; accordingly, we have strengthened the technical team in Johannesburg, to ensure that we have the capacity to deliver all aspects of the Revised Investment Plan. The increased costs of the enlarged technical team have been met by cost reductions in other areas.

“On-mine cost control remains good but the average cost per ounce continues to be adversely affected by the lower achieved grades at the current production level. The achieved grade and tonnage production in the Quarter and in the Half Year were as planned.

“Subsequent to the end of the second quarter of 2015, the price of gold fell significantly. Blanket continues to operate profitably at the lower gold price and production and costs remain as planned. If the current gold price is sustained, however, investors should revise their expectations for Caledonia’s future financial performance to reflect the prevailing environment. As production begins to increase from the first quarter of 2016, I expect that average costs per ounce will start to fall. I look forward to updating the market of our progress in due course.”

Safety

Regrettably, an accident occurred on April 30, 2015 at the GG exploration project, as a result of which a contractor died. The Directors and Management of Caledonia and Blanket express their sincere condolences to the family and colleagues of the deceased.

Exploration

Exploration continues at Blanket Mine and at its satellite properties. On 19 May 2015, Caledonia announced a resource upgrade at Blanket Mine in which 491,000 tonnes of Inferred Resources were added to the Indicated Resource category, thereby enabling this material to be included in the life of mine plan. A further 47,000 tonnes of new inventory was added to Indicated Resource. Depending on actual production rates achieved, these resources may add 12 to 15 months life to the mine plan.

Dividend Policy

Since January 2014, Caledonia has paid a quarterly dividend of 1.5 Canadian cents per share per quarter, which amounts to a total dividend of 6 Canadian cents per annum. The first quarterly dividend was paid on January 31, 2014 and subsequent quarterly dividends were paid thereafter.

It is currently envisaged that the existing dividend policy will be maintained however, the Board remains attentive to further changes in market conditions.

Strategy

Caledonia’s strategic focus is the implementation of the Revised Investment Plan at Blanket. Caledonia’s board and management believe the successful implementation of the Revised Investment Plan is in the best interests of all stakeholders because it is expected to result in increased production, reduced operating costs and greater flexibility to undertake further exploration and development, thereby safeguarding Blanket’s long term future.

Blanket will continue to explore and develop it satellite properties. Subject to the availability of funding, Blanket intends to construct a pilot plant to test material from the satellite properties so as not to compromise the existing high recovery rates which are achieved at Blanket’s metallurgical plant.

The lower gold price may create further investment opportunities in Zimbabwe and elsewhere in Anglophone sub-Saharan Africa. Caledonia will continue to evaluate such opportunities as they arise.

Effect of the Lower Gold Price

In recent months the price of gold has fallen from over US$1,200 per ounce to below US$1,100 per ounce. The lower price of gold will, if sustained, reduce Blanket’s cash generation. The implementation of the Revised Investment Plan at Blanket remains the prime focus for Caledonia and is expected to increase gold production, reduce the average cost of production and extend the life of mine by providing access to deeper levels for production and further exploration.

Caledonia has already implemented measures to reduce administrative expenses; the effects of which will be seen in coming quarters. Excluding the costs of the Zambian office, which was closed in the Quarter, the general and administrative expense in the Quarter was approximately US$1.4 million – 13% lower on an annualised basis than the expense for 2014. Caledonia’s board and management remains closely attentive to any further weakening in the gold price.

Production and costs for the Quarter and the Half Year have been as planned. However, in light of the weaker gold price, investors should revise their expectations for Caledonia’s future financial performance to reflect the prevailing environment.

Information and statements contained in this news release that are not historical facts are “forward-looking information” within the meaning of applicable securities legislation that involve risks and uncertainties relating, but not limited to Caledonia’s current expectations, intentions, plans, and beliefs. Forward-looking information can often be identified by forward-looking words such as “anticipate”, “believe”, “expect”, “goal”, “plan”, “target”, “intend”, “estimate”, “could”, “should”, “may” and “will” or the negative of these terms or similar words suggesting future outcomes, or other expectations, beliefs, plans, objectives, assumptions, intentions or statements about future events or performance. Examples of forward-looking information in this news release include: production guidance, estimates of future/targeted production rates, and our plans and timing regarding further exploration and drilling and development. This forward-looking information is based, in part, on assumptions and factors that may change or prove to be incorrect, thus causing actual results, performance or achievements to be materially different from those expressed or implied by forward-looking information. Such factors and assumptions include, but are not limited to: failure to establish estimated resources and reserves, the grade and recovery of ore which is mined varying from estimates, success of future exploration and drilling programs, reliability of drilling, sampling and assay data, assumptions regarding the representativeness of mineralization being inaccurate, success of planned metallurgical test-work, capital and operating costs varying significantly from estimates, delays in obtaining or failures to obtain required governmental, environmental or other project approvals, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects and other factors.

Potential shareholders and prospective investors should be aware that these statements are subject to known and unknown risks, uncertainties and other factors that could cause actual results to differ materially from those suggested by the forward-looking statements. Such factors include, but are not limited to: risks relating to estimates of mineral reserves and mineral resources proving to be inaccurate, fluctuations in gold price, risks and hazards associated with the business of mineral exploration, development and mining, risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom the Company does business; inadequate insurance, or inability to obtain insurance, to cover these risks and hazards, employee relations; relationships with and claims by local communities and indigenous populations; political risk; availability and increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development, including the risks of obtaining or maintaining necessary licenses and permits, diminishing quantities or grades of mineral reserves as mining occurs; global financial condition, the actual results of current exploration activities, changes to conclusions of economic evaluations, and changes in project parameters to deal with unanticipated economic or other factors, risks of increased capital and operating costs, environmental, safety or regulatory risks, expropriation, the Company’s title to properties including ownership thereof, increased competition in the mining industry for properties, equipment, qualified personnel and their costs, risks relating to the uncertainty of timing of events including targeted production rate increase and currency fluctuations.
