Nigel Robinson, Chief Executive Officer, commented:

"2018 has been transformational for us, as we have operated both of our assets for a full year, meeting our production targets for the three base metals - copper, zinc and lead.

"We are also encouraged by the results of the exploration drilling at Sasa and look forward to demonstrating the overall outcome of this work in an updated JORC compliant mineral resource estimate during the current quarter. 

"While we encountered copper mineralisation at Shuak, we believe that this is unlikely to be sufficiently material in terms of scale for us to develop. However, our business development activities gathered momentum during the second half of 2018 and we have been encouraged by some of the opportunities that we have reviewed.

"Our 2018 annual results are scheduled to be released on 10 April 2019, when our final dividend for 2018 will also be announced."

Kounrad

Kounrad Q4 2018 copper production of 3,363 tonnes brings output for 2018 to 14,049 tonnes. Total Kounrad copper production since operations commenced in 2012 is now 82,474 tonnes.  

Total copper recovered from the Western Dumps in 2018 is 8,980 tonnes, equating to approximately 64% of the amount plated.

Copper sales during Q4 2018 were 4,411 tonnes, bringing the total for the year to 14,081 tonnes. As at 31 December 2018, copper stocks at Kounrad were reduced to 28 tonnes.

Sasa

Production and sales

In Q4 2018, mined and processed ore were 205,762 tonnes and 205,130 tonnes respectively, bringing the total for 2018 to 803,101 tonnes of ore mined and 804,749 tonnes of ore processed. The average head grades for the Q4 2018 period were 3.31% zinc and 3.86% lead, and for the year were on average 3.31% and 3.90% respectively. Q4 metallurgical recoveries were 85.0% for zinc and 93.4% for lead, and for the year were on average 84.6% and 93.6% respectively.

Sasa produces a zinc concentrate and a separate lead concentrate. In Q4 2018, 11,846 tonnes of concentrate containing 48.7% zinc and 10,151 tonnes of concentrate containing 72.9% lead were produced. Total 2018 production was 46,128 tonnes of zinc concentrate at an average grade of 48.9% and 40,317 tonnes of lead concentrate at an average grade of 72.9%.   

Sasa typically receives from smelters approximately 84% of the value of its zinc in concentrate and approximately 95% of the value of its lead in concentrate. Accordingly, Q4 2018 payable production of zinc was 4,821 tonnes and of lead was 7,031 tonnes, bringing total payable production for 2018 to 18,842 tonnes of zinc and 27,919 tonnes of lead. Given that deliveries from Sasa to the smelters occur on a daily basis, payable base metal in concentrate sales for the year were very similar at 18,792 tonnes of zinc and 27,878 tonnes of lead.

During 2018, Sasa sold 375,366 ounces of payable silver that are recovered in the lead concentrate. Due to an existing streaming agreement with Osisko Gold Royalties, CAML's silver production has been pre-sold.

Development and exploration

In Q2 2017, the Sasa team commenced construction of tailings storage facility 4 (TSF4). Construction of this facility is materially complete and is now expected to be concluded in H1 2019. TSF4 should provide tailings storage for seven years.

During H2 2018, CAML commenced a 'Life of Mine' study at Sasa. This work programme will entail an in-depth review of each aspect of the Sasa operation and is expected to be completed throughout the course of 2019.

As part of the Life of Mine study, CAML undertook diamond drilling at both Svinja Reka, the location of current mining operations, and Golema Reka, which was mined between 1981 and 2010. The aim of the programme was to identify additional resource potential and to convert a portion of the inferred resources at both deposit areas into the indicated category.

Svinja Reka

Svinja Reka currently has JORC compliant inferred mineral resources of 2.7 million tonnes containing 3.2% lead and 2.1% zinc. During the year, over 3,000 metres of diamond drilling have been completed below the 830 metre level at Svinja Reka. Results over a 150 metre strike length have confirmed extensions to mineralisation down to and beneath the 750 metre level at significant intersections. CAML is encouraged that the grades identified in the area below the 830 metre level appear to be higher than the current inferred resource demonstrates.

Golema Reka

Golema Reka currently has JORC compliant inferred mineral resources of 7.4 million tonnes containing 3.7% lead and 1.5% zinc. A programme comprising over 3,000 metres of diamond drilling was undertaken at Golema Reka, generating encouraging intersections over a 350 metre strike length that demonstrate an extension of mineralisation beneath the 700 metre level. Golema Reka is accessible from the current mine infrastructure.

An updated JORC compliant mineral resource estimate reflecting both drilling programmes is expected during Q1 2019.

2019 production guidance

CAML targets 2019 Kounrad copper production of between 12,500 and 13,500 tonnes of cathode, of which approximately 70% is expected to be leached from the Western Dumps.

At Sasa, CAML expects 2019 underground ore production of between 800,000 and 825,000 tonnes. This should result in zinc in concentrate production of between 22,000 and 24,000 tonnes and lead in concentrate production of between 28,000 and 30,000 tonnes.

Business development

Shuak

During 2018, CAML completed the second exploration season at Shuak, undertaking both diamond and core hydrotransport drilling. While the results received have been encouraging, CAML is of the opinion that this project is unlikely to be of sufficient scale to warrant development by the Company. Therefore, CAML plans to return the asset to the current 20% shareholders, while retaining a Net Smelter Return ('NSR') royalty of 1.25% as per the original agreement.

Other

During 2018, CAML has screened 22 business development opportunities and conducted three site visits. The Company is currently further reviewing two potential base metals opportunities.

Cash

As of 31 December 2018, CAML had cash in the bank of $39 million.
