Mandalay Resources Corporation Announces Production and Sales Results for the Fourth Quarter and Full Year of 2015

TORONTO, Jan. 13, 2016 (GLOBE NEWSWIRE) -- Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX:MND) announced today its production and sales results for the fourth quarter and full year of 2015.

Brad Mills, Chief Executive Officer of Mandalay, commented, "We are pleased that, in the fourth quarter of 2015, Mandalay produced 43,393 saleable ounces of Gold equivalent ("Au Eq oz").  For the full year, we produced a new record of 166,679 Au Eq oz. This total annual production includes:

• A record 109,102 saleable ounces of gold ("oz Au"), at the midpoint of our 2015 guidance of 101,000 to 116,000 oz;
   
• A record 3,712 tonnes of antimony ("t Sb"), above our guidance of 3,200 to 3,500 t; and
   
• 2.5 million oz silver ("Ag"), slightly below our guidance of 2.7 to 3.1 million oz.
  
  

Metal quantities sold closely followed the produced quantities.  As is normal, fourth quarter sales of 39,877 Au Eq oz were slightly lower than production, reflecting end-of-year shipping schedules, while full-year sales at 167,808 Au Eq oz were slightly greater than production, as they included significant carryover from strong late 2014 production that was not shipped until early 2015."

Mr. Mills continued, "This excellent performance is based on our first full year as a three-mine company, with offsetting effects across the larger portfolio significantly smoothing short-term variability at any one operation.

• Costerfield was the high performing anchor to the portfolio all through 2015, producing and selling record amounts of both gold and antimony.  This is a direct result of having refined the practice of its cemented rock-fill, longhole stoping mining method at 10 metre ("m") levels in the N- and Cuffley lodes to produce ore at a higher rate and with less dilution than in previous years. This material, with higher than expected gold grades, was processed at record throughput rates in the optimized plant, which achieved strong metallurgical recoveries along with the high throughput.   Good performance at Costerfield is expected to continue in 2016 with very low risk, as all major capital programs for the currently envisioned life of mine were completed in 2015.
   
• Cerro Bayo worked its way through the planned mine-outs of the Fabiola and Dagny veins during 2015, while developing the new mines at Delia SE and Coyita.  As a result and as expected, the delivered grades and tonnes from the mines were lower than in previous years, resulting in lower metal production.  By the fourth quarter, mine production began to recover as low grade material from the older mines was replaced by higher grade material from the newer mines, particularly Delia SE.  With the developed state of its high grade ore shoots on track, Cerro Bayo is set up for expected strong 2016 performance.
   
• Björkdal made significant progress in its transformational journey in the fourth quarter of 2015. Our first test of best-practice grade control methodology in underground development during the fourth quarter was highly successful, supported by: work completed earlier in the year to improve the resource and reserve models; improved planning processes; the implementation of high-quality mapping, sampling and assaying; and dramatically shortened assay turnaround time.  The results suggest that we can discard 30-50% of low grade material mined from typical drifts and increase the grade of ore sent to the mill by a corresponding 30-50%. This will make room in the plant for significantly more high grade feed, increasing effective productive capacity measured in total gold ounces recovered.  Also encouraging is the fact that metallurgical recoveries of the selected high grade material improved with head grade, reaching about 92% at head grades of about 2 g/t, the average reserve grade.  In order to deliver sustained good results consistent with this test during 2016, we need to increase our underground mining rate (to compensate for the 30-50% of development material now being discarded) and translate the learnings about selective development to the process of planning and excavating selective stopes between developed levels.  Opportunities to improve further upon the gains from the grade control test which we will be investigating in 2016 include reducing underground mining widths (further reducing dilution and enhancing head grade now that we understand where the gold is located) and optical sorting of crushed ore to further de-select significant volumes of unveined and barren host rock before milling."
  
  

Mr. Mills closed his remarks, "Mandalay reiterates and maintains the production guidance for 2016 given with its third quarter 2015 financial results in the press release of November 5, 2015."

Table 1 - Fourth Quarter and Total Year Saleable Production for 2015 and 2014

¹ Quarterly Au Eq. oz produced is calculated by multiplying the saleable quantities of Au, Ag, and Sb in the period by the respective average market prices of the commodities in the period, adding the three amounts to get a "total contained value based on market price", and then dividing that total contained value by the average market price of Au in the period.  Average Au price in the period is calculated as the average of the daily LME PM fixes in the period, with price on weekend days and holidays taken of the last business day; average Sb price in the period is calculated as the average of the daily average of the high and low Rotterdam warehouse prices for all days in the period, with price on weekend days and holidays taken from the last business day; average Ag price in the period is calculated as the average of the daily London Broker's silver spot price for all days in the period, with price on weekend days and holidays taken from the last business day.
