Troy Resources NL: Casposo Achieves Nameplate Throughput

PERTH, WESTERN AUSTRALIA--(Marketwire - Oct. 3, 2011) - Troy Resources NL (TSX:TRY)(ASX:TRY) -


Growing dividend paying gold producer, Troy Resources NLtoday announced that it had achieved nameplate throughput levels at its high-grade Casposo gold and silver mine in San Juan Province, Argentina.

Commenting on the results, Troy's CEO, Paul Benson said, "We are very pleased to have reached this milestone. Although it has taken us longer than planned, the team on site led by Ken Nilsson have done a tremendous job overcoming the initial project commissioning issues and then challenges thrown up by the worst winter in the region in 50 years."

"Over the last 3 weeks the plant has exceeded the nameplate capacity of 1100 tonnes per day (tpd) on 4 occasions and the 10 day moving average is running at over 1000 tpd. Importantly from a process control perspective, the daily variation is reducing and operations are much more stable. In September the site produced approximately 6,600oz of gold which is 50% more than the previous best month's production in April."

As previously announced to the market the Casposo operation in San Juan Province, Argentina, was impacted by freezing weather during the coldest winter in the region in 50 years. A series of cold fronts passed across the site from late June through mid-August with periods where maximum day time temperatures reached -9ºC and minimum night temperatures -18ºC and wind chill of an additional -10ºC.

Each freezing event brought production to a halt freezing pipes, pumps and filters and degrading the performance of chemicals used in the processing plant. The impact can be seen in the graph on the following page. With multiple closures and restricted operations the 10 day moving average of tonnes processed per day trended down for most of the period. The interruptions also had a negative impact on metallurgical recoveries during the quarter although these have also improved in the latter part of September as operations returned to normal.

As noted, with the onset of more normal weather patterns, the plant has been able to steadily increase throughput. Over the last 3 weeks daily throughput has exceeded the nameplate 1100 tonnes per day (tpd) on 4 occasions and the 10 day moving average is running over 1000 tpd. Work has commenced to modify the relevant parts of the plant to minimise the impact should similar freezing conditions reoccur in the future.

As shown in the table below, quarterly gold production was down slightly compared to the previous quarter however, the strong increase in Casposo's production can be seen in the month of September as throughput steadily increased and operating variability decreased. In September the site produced approximately 6,600oz of gold which is 50% more than the previous best month's production in April.

Production (ounces) July August September
) September Quarter (estimate ) June Quarter
Andorinhas Au 5,585 3,958 3,350 12,890 14,732
Casposo Au 1,748 2,726 6,600 11,070 11,562
Casposo Ag 28,489 29,812 82,000 140,300 140,310
Total Company Gold 7,333 6,684 9,950 23,970 26,294
Total Company Gold Equivalent 7,980 7,346 11,540 26,870 29,644

The Casposo plant is still in the process of optimisation and it will not be possible to accurately assess ongoing operating costs until the plant has been operating consistently at or around nameplate capacity and the build-up of stores and ongoing consumables has reached a sustainable level. Standard operating and cash cost data will be published in the September quarterly report scheduled to be released to the market before October 28.

Casposo's September quarter unit costs are expected to be higher than the June quarter and what would be expected once stable production is achieved due to; lower gold production, additional costs incurred during this challenging weather environment, start up and testing costs, and with general inflationary pressures within Argentina. Power costs are expected to fall in the December quarter as the site moves from onsite diesel generated power to grid power.

This report contains forward-looking statements, statements, including those relating to expected production levels. These forward-looking statements reflect management's current beliefs based on information currently available to management and are based on what management believes to be reasonable assumptions. A number of factors could cause actual results, performance, or achievements to differ materially from the results expressed or implied in the forward looking statements.
