(all figures in US dollars unless otherwise noted)
ELD No. 15-08
TSX: ELD NYSE: EGO
Highlights
- Estimated total capital expenditure for the concentrator upgrade and mine development for Phase II through 2015-2016 is
$83M . - Estimated average annual production during the first full 4 years of Phase II (excluding ramp-up in 2016):
- 60,725 ounces of gold
- 1.1 million ounces of silver
- 12,200 tonnes of lead
- 12,900 tonnes of zinc
- Estimated average cash operating costs of
$309 /oz (including by-product credits) during the first full 4 years of Phase II (excluding ramp-up in 2016). - Overall metal recovery in the flotation circuit is estimated to be 89% for lead, 94% for zinc, 92% for silver and 88% for gold.
- The project is projected to generate
~$618M of pre-tax revenue during the first five years of Phase II operations, from 2016-2020.
Phase I
During this initial phase of operations, pyrite tailings previously deposited in the Olympias tailings management facility (TMF) are being reclaimed and reprocessed through the concentrator to recover a gold concentrate. Tailings are reground in a ball mill at a throughput of 2,400 tonnes per day (tpd) then processed through a single stream flotation circuit to recover gold bearing pyrite concentrate for sale offshore. Tailings from this process are then transferred to the centrally located Kokkinolakas TMF, which services both the Olympias and
Historic underground mining at Olympias for lead and zinc (1976-1995) used a combination of sub-level caving and drift and fill methods. In 2012,
Phase II
The second phase of operations will include the conversion of the concentrator to a differential flotation circuit producing lead, zinc and gold concentrates, which is expected to be sold through offshore contracts. The concentrator is designed to be operated at a throughput of 385,000 tonnes per annum (tpa) as set out in the approved Environmental Impact Assessment (EIA) for the Kassandra Mines.1
Development of the underground mining operation to support Phase II production has involved continued rehabilitation of existing drives and development of new access to the ore. A total of 13,000 meters of mine development has been completed to date. Drift and fill stoping with paste backfill has been selected as the most effective mining method for the orebody. Consolidated paste backfill is expected to provide necessary support for the mining operations. Due to the high mass pull for the concentrates, the majority of tailings produced from the flotation circuit are expected to be used as mine backfill. Sufficient mine development and infrastructure is expected to be in place to support ramping up underground ore production starting in Q2 2016. The opportunity exists in the new circuit to increase production beyond the stated throughput with minimal investment, should it be chosen in the future. It is estimated Phase II will operate for approximately 6-8 years.
Implementation and Operating Performance
Phase II engineering and design is well underway, with some site preparation in progress, and on schedule to initiate construction of Phase II in Q4 2015. During the preparations for Phase II, the concentrator plant will be shut down for installation of the three flotation circuits. Prior to the shutdown, rehabilitation work will be carried out in a number of areas including replacement of the crushing facilities for mine ore, modifications to the thickening and filtration circuits, and the installation of a new ball mill to treat the underground ore. The work required to bring the plant up to a nominal design capacity of 385,000 tpa will be completed in mid-2016.
The estimated cost of conversion of the concentrator for differential flotation plus refurbishment of the crushing and grinding circuits and addition of a paste backfill plant is approximately

Phase III
The design of Olympias Phase III is currently under way. Phase III is designed to include the completion of the main decline accessing the bottom of the Olympias orebody, and installation of underground materials handling facilities for ore, waste and mine backfill. In Phase III, the mine is designed to be operated at a nominal throughput of 800,000 tpa, as per the EIA approved by the Greek authorities, providing feed for a new concentrator and gold recovery circuit.
