Lydian Announces Initial Capital and Operating Cost Reductions From the Amulsar Value Engineering and Optimization Study
TORONTO, Nov. 19, 2015 (GLOBE NEWSWIRE) -- Lydian International Limited (TSX:LYD) ("Lydian" or "the Company") is pleased to announce the results of a value engineering and optimization study for its 100%-owned Amulsar Gold Project in south-central Armenia. Pre-production capital costs decreased by 13% to $370 million and all-in sustaining costs decreased by 17% to $585/oz of gold. All dollar amounts in this news release are presented in U.S. dollars unless otherwise noted.
Howard Stevenson, Lydian's President and CEO, stated, "We set out to reduce capital expenditures without negatively impacting operating costs. This $56 million capital cost reduction met our target. Combining this outcome with a decrease of more than $100/oz in all-in sustaining costs greatly enhances Amulsar's economics. Amulsar will be a very low-cost gold producer of excellent scale. We will produce 2.1 million ounces of gold from the current mine plan, and we see strong opportunity for orebody-growth."
Results of the value engineering program include:
Initial capital costs of $370 million, a $56 million reduction from the October 2014 technical report (the "2014 Technical Report");
All-in sustaining costs reduced to $585/oz of gold, down from $701/oz of gold based on the 2014 Technical Report;
Operating cost reductions reflecting a lower 2.4:1 W:O stripping ratio and decreases in key consumables including electricity, diesel and reagents;
Total recoverable gold of 2.1 million ounces over a 10 year mine life;
Gold production averaging 243,000 ounces per year during the first five years and an overall average of 211,000 ounces per year over the life of mine;
Accelerated after-tax cash flows of $567 million during the first five years of operations to support early payback of project debt and equipment financing;
Over 100 million tonnes of inferred mineral resources and potentially mineralized zones adjacent to and below currently defined mineral resources and reserves; and
After-tax unleveraged IRR of 21.6% and NPV of $338 million based on a discount rate of 5% and a gold price of $1,150 per ounce.
Mr. Stevenson added, "Value engineering results are based solely on mineral reserves defined as 96.7 Mt, containing 2.4 million ounces of gold. Economic results may be enhanced by additional drilling as mining operations begin, potentially resulting in conversions of inferred mineral resources into proven and probable mineral reserves. Inferred mineral resources include 106 Mt containing 2.0 million ounces of gold. Of this, 26 Mt containing an estimated 0.5 million ounces of gold are within the presently defined mine plan and classified as waste."
Lydian undertook an optimization exercise for Amulsar earlier during 2015. The objective was to reduce capital expenditures without negatively impacting operating costs or adversely affecting environmental and social impacts. To support this process, the Company commissioned Samuel Engineering Inc. ("Samuel") to review a number of engineering design concepts and incorporate the findings into an updated technical report (the "Q4 2015 Technical Report").
Results of the study demonstrate that initial capital costs will be reduced to $370 million. Operating cost improvements will also be realized, with all-in sustaining costs estimated to decrease from $701/oz of gold to $585/oz of gold produced. Lower costs resulted, in part, from a decrease in the stripping ratio; the optimized layout and flow sheet leading to favorable reductions in consumables such as diesel, electricity and reagents; and a higher percentage of gold ounces recovered per tonne of ore mined and processed.
The study was prepared by Samuel in accordance with the CIM Definition Standards on Mineral Resources and Mineral Reserves referred to in NI 43-101, and is a mining study for the purposes of NI 43-101.
The Q4 2015 Technical Report incorporates results of the value engineering program that has occurred since completion of the 2014 Technical Report. The following table compares key outcomes of the Q4 2015 Technical Report with those of the 2014 Technical Report:
Economic results for the Q4 2015 Technical Report were based on a gold price of $1,150/oz and a silver price of $16/oz. For purposes of comparing the Q4 2015 Technical Report to the 2014 Technical Report, financial results were based on a gold price of $1,250/oz and a silver price of $20/oz.
Key Design Modifications and Assumptions
Crushing facility – This year's metallurgical testwork, together with all previous testwork and an assessment of the rock quality of the orebody, has led to the crush size being increased to 19 mm from the previous 12.5 mm with no loss in gold recoveries. This has allowed us to eliminate three of five cone crushers from the secondary and tertiary circuits and reduce the number of double deck screens from five to three. The primary gyratory crusher will be replaced by a jaw crusher.
Overland conveyor – The overland conveyor route and design have been modified. The revised route will reduce the length of the conveyor to 5.3 Km, a reduction of approximately 15%. Design modifications will result in a single conveyor on-grade. The previous design contemplated two partially elevated conveyors with a transfer station.
Infrastructure – Infrastructure was relocated to consolidate facility footprints and improve constructability and operability. This included moving the main haul road from the east side to the west side of the ridge line, relocating the truck shop to a lower elevation and adjacent to administrative facilities, eliminating the second sub-station, siting the remaining sub-station in a centralized and accessible location along the conveyor corridor, and moving the ADR plant adjacent to the process pond near the base of the heap leach facility.
Mining – Pre-production mine development was increased to provide early access to sufficient ore faces, and the mining rate was moderated to reflect expectations of start-up operating conditions. This allowed a staged approach to mine fleet additions during the first 24 months of operations. However, total ore mined and delivered to the heap leach facility during the initial three years of operations only declined by 1.5% because of mine plan revisions and the noted design changes to the crushing facility which can now accommodate up to 10.5 Mtpy.
Processing – The recent metallurgical testwork demonstrated that the difference of gold extraction between 12.5 and 19 mm crush sizes for the ore bodies are not statistically significant. Gold extraction at a 19 mm crush size was also consistent with previous testwork, leading to a higher level of confidence. As a result, the overall gold recovery percentage was increased to 87.2%.
Mineral Resource Estimate
The independent mineral resource estimate was prepared by AMC Consultants (UK) Limited ("AMC"). Mineral resources were estimated in conformity with generally accepted CIM "Estimation of Mineral Resource and Mineral Reserves Best Practices" guidelines and are classified according to the "CIM Standards on Mineral Resources and Reserves: Definition and Guidelines" (November, 2010). The resource estimate stated here is the same mineral resource estimate stated in both the 2014 Technical Report and May 2015 technical report of the Company.

Total Measured and Indicated
Notes to Mineral Resource Statement:
The effective date of the mineral resource estimate was August 29, 2014.
A cut-off grade of 0.20 g/t gold for this Project based on an optimized open-pit shell based on a gold price of US$1,500/oz of gold and assuming an open-pit mining scenario.
Figures have been rounded to the appropriate level of precision for the reporting of Indicated and Inferred Resources in the upper and lower volcanic units.
Due to rounding, some columns or rows may not compute exactly as shown.
Mineral Resources are reported inclusive of Mineral Reserves.
Mineral Resources in this statement are not Mineral Reserves and do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. Mineral Reserves have been previously reported for this Project using a prior Mineral Resource statement.
Mineral Reserve Estimate
The independent mineral reserve estimate was prepared by Mine Development Associates ("MDA"). MDA classifies reserves in order of increasing confidence into probable and proven categories in accordance with the "CIM Definition Standards – For Mineral Resources and Mineral Reserves" (2014) and therefore NI 43-101.
The mineral reserve estimate is based on the August 29, 2014 AMC mineral resource model. The resource block model was updated in May 2015 by AMC. The measured and indicated resources were evaluated to determine the minable portion by first using pit optimization techniques and then using the optimization templates to design pit phases and a final design. A production schedule was created from the design pit phases, which forms the basis of the economic evaluation for this study.
Mineral Reserve Statement (0.20 g Au/t cutoff)
Mine Development Associates, 23 October 2015
Total Proven & Probable Reserves
Notes to Mineral Reserve Statement:
The pit design was based on an optimization shell generated on gold only at a gold price of $912/oz.
The economic evaluations were based on a gold price of $1150/oz and a silver price of $16.00/oz.
A diluted gold cut-off grade of 0.20 g/t was used for processing.
The effective date of this mineral reserve estimate is October 23, 2015.
The Q4 2015 Technical Report mineral reserves declined by 3.7 million tonnes compared to the 2014 Technical Report mineral reserves due, in part, to a biodiversity exclusion zone boundary and the haul road located close to the Erato final pit design. Waste stripping has been reduced by approximately 56 million tonnes, mostly due to variable slope angles per rock type rather than using an average slope angle for the pits.
Pre-Production Capital Costs
Pre-production capital costs total $369.9 million, a $56.2 million reduction from the 2014 Technical Report. This cost estimate addresses engineering, procurement, construction, owner's costs, and start-up of the 10.5 Mtpy mine and process facility. The table below summarizes pre-production capital costs.

All-in Sustaining Costs
Total cash costs (C2) of $509/oz of gold sold represents a $133/oz decrease from the results of the 2014 Technical Report. This decrease reflects benefits from a number of factors, including: a decline in diesel costs, weakening of the Armenian dram, reduced loading and haulage costs due to use of larger equipment, reduced energy consumption resulting from redesign of the crushing facility and less solution pumping requirements, lower reagent consumptions, and overall higher gold recovery per tonne of ore mined and processed.
Sensitivity to Gold Price
Reducing operating costs has decreased the project's sensitivity to the gold price as demonstrated in the following table of key after-tax financial parameters.

Amulsar Gold Project Description
The Amulsar Gold Project is located in south-central Armenia roughly 115 Km in a direct line to the southeast of the capital Yerevan or a 170 Km drive by paved road. The Amulsar property comprises mountainous terrain with the prominent feature of an approximately seven Km long northwest-southeast trending ridge. The gold ore deposit is located within three ridge peaks (Erato, Tigranes and Artavasdes) at 2,500 to 2,988 meters above sea level. The heap leach facility will be located in a valley at lower elevations providing nominal top surface elevations ranging from 1,664 to 1,856 meters above sea level.
All major infrastructural needs are readily accessible, including high tension power lines, a gas pipeline, a fiber optic internet cable, on-site sources of water, and regional labor sources. The sealed highway to Yerevan is immediately adjacent to the Amulsar project site. The closest town to the Project is Jermuk, which is situated approximately 11 Km north from the Project's infrastructure. There are also four rural communities in proximity to the Project, including Kechut, Saravan (including Saralanj and Ughedzor), and Gndevaz.
The Company's planned operations contemplate an owner-operated mining fleet delivering run-of-mine ore at a nominal rate of 10.5 Mtpy from the three open pits to the crushing facility. The ore will be reduced in size through a two-stage crushing facility to 100% passing 19 mm. The crushed ore will be transported approximately 5.3 Km via overland conveyor to a crushed ore stockpile. From there, it will be reclaimed by belt feeders underneath the stockpile and transferred by conveyor to a loadout bin. Lime will be added to the ore for pH control and trucks will haul the ore approximately 0.5 Km to the heap leach pad for stacking.
The planned heap leach facility consists of the lined leach pad and collection ponds. The leach pad will be constructed in four phases with a total ore heap stacking capacity of 104 Mt over the 10 year project life. The collection ponds will include the process pond and three storm event ponds. Process solution and storm/snowmelt water will flow from the leach pad and will gravity-drain through a spillway from the pad to the process pond. Spillways will connect the ponds for potential runoff overflows.
Stacked ore on the heap leach pad will be treated by applying leach solution. The design leaching cycle of the ore heap is 60 days. Over 80% of the recoverable gold is expected to be recovered during this leach cycle. Pregnant leach solution will be collected in the process pond and then pumped into the adjacent ADR plant for processing. Filter cake bearing the precipitated gold and silver will then be dried and smelted into doré bars. Doré will be shipped offsite to be refined and sold. Overall gold recovery is expected to be 87.2%.

Cautionary Note concerning estimates of Measured, Indicated and Inferred Mineral Resources
This news release uses terms that comply with reporting standards in Canada and certain estimates are made in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes Canadian standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission ("SEC"), and mineral resource information contained herein may not be comparable to similar information disclosed by United States companies. This news release uses the terms "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" to comply with reporting standards in Canada. We advise United States investors that while such terms are recognized and required by Canadian regulations, the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in such categories will ever be converted into mineral reserves under SEC definitions. These terms have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. Therefore, United States investors are also cautioned not to assume that all or any part of the "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" exist. In accordance with Canadian rules, estimates of "inferred mineral resources" cannot form the basis of pre-feasibility or other economic studies. It cannot be assumed that all or any part of the "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" will ever be upgraded to a higher category.
Financial Definitions—Non-GAAP Measures
"Total Cash Costs" figures are non-GAAP measures which are calculated in accordance with a standard developed by The Gold Institute, a worldwide association of suppliers of gold and gold products and included leading gold producers from North America that ceased operations in 2002. Adoption of the standard is voluntary and the cost measures presented may or may not be comparable to other similarly titled measures from other gold companies. Total cash costs for Lydian were calculated and defined to include the addition of mining costs, processing costs, general and administrative costs, off site refining and transportation of bullion costs, the Newmont royalty, and the Armenian mining royalty tax on gross revenues. The sum of these components are reduced by the estimate of by-product credits. This sum is then divided by tonnes of ore or ounces of gold to attain Total Cash Costs on a per tonne ore or per ounce of gold basis. These measures are considered to be key indicators of a company's ability to generate operating earnings and cash flow from its mining operations. This data is furnished to provide additional information and is a non-GAAP measure specific to the gold mining industry. Total cash costs do not have standardized definitions under GAAP and may not be comparable to other measures. It should not be considered in isolation as a substitute for other measures of performance and it is not necessarily indicative of operating costs presented under GAAP.
"All-in Sustaining Costs" were determined using guidance announced in 2013 from the World Gold Council. Reported values were calculated by Lydian as the sum of the Total Cash Costs, corporate general and administrative costs (estimated to be approximately $5 million per year) and sustaining capital. This sum is then divided by tonnes of ore or ounces of gold to attain All-in Sustaining Costs on a per tonne ore or per ounce of gold basis. This non-GAAP measure provides further transparency into costs associated with producing gold and will assist analysts, investors and other stakeholders of the company in assessing the Amulsar Gold Project expected operating performance, ability to generate free cash flow and its overall value. This data is furnished to provide additional information and is a non-GAAP measure. All-in sustaining costs do not have standardized definitions under GAAP and may not be comparable to other measures. It should not be considered in isolation or as a substitute for other GAAP conforming measures.
