TORONTO, ONTARIO--(Marketwire - April 24, 2012) - High River Gold Mines Ltd. (News - Market indicators) ("High River" or the "Company") announces its production results for the first quarter ending March 31, 2012.

Highlights

Overview

In Q1 2012, production decreased by 7% to 84.4 koz compared to Q1 2011 production of 90.5 koz. Buryatzoloto was an outperforming y-o-y mine, while Taparko and Berezitovy were underperformers with lower production y-o-y. The main reasons for this underperformance are temporary mechanical bottlenecks that have been largely solved during the first quarter 2012. A more detailed explanation is provided in the mine site summary below.

Despite the temporary operational matters at certain minesites, the Company remains on track to achieve full year production target of 380-400 koz in 2012. Management expects a skew toward the second half driven by the new heap leach launch at Berezitovy mine. The production volumes at the Taparko and Berezitovy mines should be reflected by elimination of mechanical bottlenecks at these mines during Q1 2012.

Revenue from metal sales was US$141 million in Q1 2012, versus US$127 million during the same period in 2011, an increase of 11% reflecting stronger average realized gold price of US$1,676 per ounce, 19% higher than in the comparable period in 2011.

Mine site summary

Burkina Faso

Processing

Ore processing increased by 6% in Q1 2012, which partially offset a slight deterioration in head grade at this mine. We processed c.404,000 tonnes of ore in Q1 2012, an increase of 6% on the same period last year.

Head Grade

Overall head grade in the first quarter was 3.03 g/t at this facility, compared to 3.46 g/t in the first quarter of last year, due to mine plan variations

Recovery

In the first quarter, Taparko was influenced by two factors affecting recovery - we processed more ore, while head grade was lower. As a result, recovery reduced by 2% from 86.7% in the first quarter of 2011 to 84.7% in the first quarter of this year.

We are working on several upgrades which should significantly improve recovery at Taparko starting from Q3. These include the installation of a regrind and two leach tanks to increase recovery by about 5%, as well as a mobile crusher to reduce the impact of the rainy season.

Russia

Processing

Ore processing has increased due to better availability of the mills at both Irokinda and Zun Holba head grade.

Head Grade

Head grade reduced slightly due to mine plan scheduling. According to the mine plan, we are expecting better grades for the remainder of the year.

Recovery

The Company completed a recovery improvement program at Buryatzoloto in the end of last year, the benefits of which we are now beginning to see in the recovery rates.

Processing

In November 2011 a pinion of the SAG mill at failed. It was immediately replaced with a temporary unit that enabled the plant to work at 75% of its design capacity. We expect to fully eliminate this bottleneck in early May when a new gear shaft is received.

An installation of a secondary crusher in June should further improve plant productivity by reducing the size of SAG mill feed.

Head Grade

Head grade available for mining has been higher than in Q1 of last year. We expect head grade to moderate in H2 2012.

Recovery

The observed recovery is largely flat and slightly above plant's design recovery.

Exploration & Development

Bissa

The main achievement for Q1 2012 was construction of the dam that was started in February 2012 with the clear target to finish all ground works before the end of May. That was one of the most significant challenges that might negatively influence production volumes for the first year for Bissa. The dam allows us to collect the appropriate amount of water during the rainy season and be prepared for the beginning of production.

We have now received half of the mining fleet on site with the expectation for the remainder to be delivered in July. Onsite we now have ten dump trucks, two graders, three excavators, one telehandler, one dozer and three loaders.

Plant construction is also underway: we have built a foundation for the leaching tanks and started construction of those tanks. The mill delivery is also underway with the scheduled arrival time in the second half of June. We are currently working on the foundation for the mills, and during the first quarter construction advanced significantly. A further update on the progress of construction will be given at the Company's interim results. At the end of March, we started construction of the ROM pad and crusher. We are also on track to erect the onsite LFO\HFO power generators.

During the first quarter this year we have been working on the camp for mine employees and we are proud to state that the camp is now almost 100% complete, and we are only awaiting some kitchen equipment and final completion of the swimming pool.

We are currently in the design phase for the tailing dam, which is on time with our development plan for the overall project.

We reached an agreement with the government and local communities on the relocation of two small villages that will be affected by future mine operations. New villages for the relocated communities are built, which retained the approximate layout of the existing villages, reflecting our belief that the shape of communities is important to their success. We also provided social infrastructure and services to the relocated villages, including a water supply, medical center, school, church, mosque, and a community meeting place.

The project is well on track to deliver first gold in 1H13.
