Excellon Reports Second Quarter 2016 Production

TORONTO, ON--(Marketwired - August 02, 2016) - Excellon Resources Inc. (TSX: EXN) (OTC: EXLLF) ("Excellon" or the "Company"),Mexico's highest grade silver producer, is pleased to announce second quarter 2016 production results from the La Platosa Mine in Durango, Mexico.

Q2 2016 Production Highlights (Compared to Q2 2015)

  • Silver equivalent ("AgEq") production of 368,568 ounces (Q2 2015 -- 341,975 AgEq oz), an 8% increase
  • Silver production of 227,826 ounces (Q2 2015 -- 182,709 ounces), a 25% increase
  • Lead production of 1.3 million lb (Q2 2015 -- 1.0 million lb), a 28% increase
  • Zinc production of 1.6 million lb (Q2 2015 -- 1.7 million lb), a 10% decrease
  • Phases II and III of optimization program underway with increasingly dry mining conditions at Platosa and drawdown rates exceeding projections at current pumping rates

"Production during the second quarter remained steady and slightly improved from Q1," stated Brendan Cahill, President and Chief Executive Officer. "As a result of drier underground conditions, we accessed the second level of the Rodilla Manto where further high grade mineralization was mined. With operations on firmer track as a result of our continued efforts to improve operational efficiencies, we expect these improvements to reflect well in our operating costs during the quarter, further benefitted by higher commodity prices. As we move into the third quarter of 2016, we intend to remain focused on improving our operations through the ongoing optimization program, while carrying out exploration drilling near existing infrastructure and following up on high priority, drill-ready targets."

Ore production during the second quarter was primarily from the Rodilla, 6A and Guadalupe North and South mantos. A total of 14,453 tonnes of ore was processed during the quarter, a 5% increase from the previous quarter. As the Company continued to access the Rodilla Manto ahead of schedule due to drier mining conditions, approximately 10,795 tonnes of ore were mined from the Rodilla Manto alone, with grades from Rodilla averaging approximately 662 g/t Ag, 5.94% Pb and 7.75% Zn. During Q3, the Company aims to continue production from the Rodilla Manto on the 975 level while continuing development and accessing ore from the 970 level, with development preparing the 960 level for Q4. Additionally, development is focused on further accessing the Guadalupe South Manto and driving development into the 623 Manto, hosting mineral resources of 83,000 tonnes at 1,231 g/t Ag (1,766 g/t AgEq).

As delineated in the Platosa resource block model, the upper levels of the Rodilla Manto host mineralization grading approximately 800 g/t Ag, 7% Pb and 10% Zn on an undiluted basis. During the second quarter, the Company continued to encounter materially higher grades than forecast from Rodilla, with approximately 1,700 tonnes of ore produced from Rodilla grading in excess of 1,000 g/t Ag, 10% Pb and 10% Zn on a diluted basis. Though the deposit is tightly drilled at 15 metre centres, manto boundaries are generally erratic and additional mineralization is often encountered outside of the resource block model. Additionally, the Company has noted historically that in areas with very high argentiferous-galena content silver and lead grades are underestimated as such mineralization may be washed out and lost during the diamond drilling process.

Approximately 1,850 tonnes of ore milled during the quarter were extracted from historic stockpiles and settling ponds at Platosa at minimal cost with grades of approximately 150 g/t Ag and 1-2% Pb and Zn. High-grade ore produced during the quarter was blended with this lower grade material to improve recoveries and concentrate payability. The Company expects to continue accessing and blending this low cost ore in coming quarters.

Update on Optimization Plan

As announced on June 2nd and November 2nd, 2015, the Company has developed an optimization plan to comprehensively manage water at Platosa through an enhanced pumping system. The Company is currently implementing the second and third phases of the program, with the drilling of primary dewatering wells and installation of submersible pumps. Additionally, the Company has further optimized its existing pump infrastructure, which demonstrated exceptional results during the second quarter. Effectively all areas of the mine are currently dry, with operations only being limited by potential water inflows and pressure in the deepest areas of the mine (the production headings in Guadalupe South and development headings into the 623 Manto), and conditions in those areas are expected to improve as drawdown continues. Pumping rates (primarily from existing infrastructure) during June 2016 averaged approximately 15,900 gallons per minute, resulting in a drawdown of approximately 1.5metres during the month, approximately 30% higher than predicted in the conservative drawdown model on which the optimization plan is based. More generally, the drawdown rate throughout 2016 has exceeded the expected drawdown at various pumping rates. Drawdown rates are expected to fluctuate from period to period, but the higher than expected drawdown at consistently higher pumping rates is a promising indicator of the project's upside efficacy.

All equipment required to equip the first eight dewatering wells is expected to be on site by the end of August. Three dewatering wells have been drilled to date. The initial drilling contractor was replaced in the second quarter to improve drilling performance and drilling has now resumed. Temporary, high head pumps have been installed to draw water from the initial wells prior to installation of the permanent pumping system, with further opportunities to optimize this interim system under implementation. Further updates on the progress of this program will be provided regularly during the implementation period.

The Company expects to release second quarter financial results prior to market open on August 8, 2016.
