Alacer Gold Announces a New Reserve for Its Gediktepe Project Providing Future Growth
TORONTO, Sept. 13, 2016 (GLOBE NEWSWIRE) -- Alacer Gold Corp. (“Alacer” or the “Corporation”) (TSX:ASR) (ASX:AQG) is pleased to announce positive results from the Prefeasibility Study (“PFS”) establishing a maiden resource and reserve for the 50%1 owned Gediktepe Project (formerly known as Dursunbey) in Western Turkey.
Rod Antal, Alacer’s President & Chief Executive Officer, stated, “We are excited to announce the significant milestone achieved at Gediktepe. The PFS demonstrates that Gediktepe is an economic and technically viable project and establishes it as a valuable part of our portfolio of mining assets.
It is an outstanding result and a credit to our partner, Lidya Mining, and to our team who have converted a grassroots exploration target into a discovery and advanced it to a PFS study, all in the span of just four years. Not only does this achievement illustrate our ability to capture and convert value from exploration, it also demonstrates the great prospectivity in Turkey.
The Gediktepe project has moved into a detailed study phase where we will complete basic engineering and more technical studies. Permitting and some site preparations will be undertaken concurrent with these detailed studies. During this period, the various options for development of Gediktepe will be assessed.”
Key Highlights
(all currency in US dollars and all metrics on a 100% basis)
The Gediktepe Project is located in Balıkesir Province, about 370 km west of Ankara and 190 km to the south of Istanbul. Gediktepe will be owned on a 50%/50% basis with our joint venture partner, Lidya Mining, upon completion of the claw back right exercised by Alacer. The estimated claw back cost is $7.1 million at June 30, 2016. Lidya Mining is the operator of Gediktepe.
Gediktepe is a polymetallic orebody that contains economic values for gold, silver, copper and zinc. The sulfide deposit is overlain with oxide ore containing gold and silver which is amenable to heap leaching. Gediktepe will be an open pit mine and the oxide ore will be processed first, providing cash flow for the development and subsequent processing of the more prevalent sulfide ore. The sulfide ore contains gold, silver, copper and zinc and will be processed through a multi-stage flotation circuit producing two marketable concentrates.

Gediktepe Overview
http://www.globenewswire.com/NewsRoom/AttachmentNg/884bffe5-3088-4836-a8fa-b6a8f5c20c8d
The Gediktepe deposit was discovered in April 2013 with the second drill hole (DRD-002) intersecting 26.5m at 7.9g/t gold and 77g/t silver from surface6. Oxide mineralization is enriched in gold and silver, whereas sulfide mineralization includes gold, silver, copper and zinc. The deposit continues to be open at depth and along strike.
Production and Cost Summary
Gediktepe will be an open pit mine and is well serviced being close to existing infrastructure and connects to the national power grid. Production at Gediktepe will start with the processing of oxide ores using a conventional heap leach and Merrill Crowe process (gold and silver precipitation by zinc). The Merrill Crowe plant recovers more silver than a carbon adsorption process and is appropriate for this deposit due to the high silver content in the oxide ores. Average life-of mine recoveries for the oxide ore is 83% for gold and 45% for silver.
Production will transition from oxide processing to sulfide processing in year 3 of the operation. Sulfide ore processing will be via two 4 stage flotation circuits, one for copper recovery and one for zinc recovery. The flotation circuits will produce concentrates that will be shipped offsite for processing through copper and zinc smelters. Metallurgical tests for the sulfide flotation of Gediktepe ores yielded recoveries in copper concentrate of 69% for copper, 17% for gold and 12% for silver and recoveries in zinc concentrate of 82% for zinc, 16% for gold and 22% for silver.

About Alacer
Alacer is a leading intermediate gold mining company, with an 80% interest in the world-class Çöpler Gold Mine in Turkey operated by Anagold Madencilik Sanayi ve Ticaret A.S. (“Anagold”), and the remaining 20% owned by Lidya Madencilik Sanayi ve Ticaret A.S. (“Lidya”). The Corporation’s primary focus is to leverage its cornerstone Çöpler Mine and strong balance sheet to maximize portfolio value, maximize free cash flow, minimize project risk and, therefore, create maximum value for shareholders.
The Çöpler Mine is located in east-central Turkey in the Erzincan Province, approximately 700 miles southeast from Istanbul, Turkey and 340 miles east from Ankara, Turkey’s capital city.
Alacer is actively pursuing initiatives to enhance value beyond the current mine plan:
- Çöpler Oxide Production Optimization – expansion of the existing heap leach pad to 58 million tonnes continues to advance. All required land use permits for the Heap Leach Pad Phase 4 (“HLP4”) expansion have been received. The Corporation continues to evaluate opportunities to optimize and extend oxide production beyond the current reserves, including a new heap leach pad site to the west of the Çöpler Mine.
- Çöpler Sulfide Project – the Sulfide Project will deliver long-term growth with robust financial returns and adds over 20 years of production at Çöpler. The Sulfide Project will bring Çöpler’s remaining life- of-mine gold production to 4 million ounces at All-in Sustaining Costs3 averaging $645 per ounce. The Environmental Impact Assessment and all required land use permits for construction have been approved. Detailed information regarding the Çöpler Sulfide Project can be found in the Technical Report dated June 9, 2016 entitled “Technical Report on the Çöpler Mine and Çöpler Sulfide Expansion Project” (“the Updated Technical Report”) available on SEDAR at www.sedar.com and on the Corporation’s website.
- The Corporation continues to pursue opportunities to further expand its current operating base and to become a sustainable multi-mine producer with a focus on Turkey. The systematic and focused exploration efforts in the Çöpler District, as well as in other regions of Turkey are progressing. Çakmaktepe Southeast, Çakmaktepe East, Çakmaktepe North and Bayramdere are the main focus in the Çöpler District, which are shallow, oxide targets with favorable metallurgy and have the potential to add oxide production within the next two years. In the region, Gediktepe Project has advanced with a maiden resource and reserve released in third quarter 2016 and development options are being evaluated.
Alacer is a Canadian corporation incorporated in the Yukon Territory with its primary listing on the Toronto Stock Exchange. The Corporation also has a secondary listing on the Australian Securities Exchange where CDIs trade.

Geology and Geological Interpretation
The Gediktepe project is a massive sulfide hosted in metamorphic schist units. The upper portion of the deposit has been oxidized by surface and ground water. The oxide zone is nearly void of base metals. The sulfide zone is polymetallic with economic values of zinc, copper, gold and silver. The major economic minerals are sphalerite and chalcopyrite. Pyrite is present throughout.
Drilling completed through August 5, 2015 was used to generate the geologic model and estimate mineral resources. The mineral resource is based on a combination of Reverse circulation (RC) and diamond core drilling for a total of 487 holes. RC drilling was utilized for 184 holes and the remaining 303 holes were by diamond drilling.
Mineralized bodies strike to the northeast and dip to the northwest at about 20 degrees. Mineralization resides primarily within the Chlorite-Sericite Schist. Where oxidized, gold and silver remains within iron oxide gossan. For the sulfide zone, massive pyrite forms lenses containing sphalerite, terahedrite, chalcopyrite and galena.
The geologic model contains various schist units and ore types used within the resource model to define grade boundaries. The geologic and resource model used both the RC drilling and core holes to model boundaries and estimate metal grade.
Drilling Techniques
Drilling is primarily vertically oriented holes with a limited number of high angle drill holes. Approximately 38% of the drilling was RC with 62% diamond drill core. Drill hole spacing in Gediktepe varies from 25 m to 50 m centres. The central portion of the mineralized body is drilled at 25 m spacing with outer regions drilled to 50 m centres (refer to “Diagrams” in Section 2 of JORC Table 1 showing hole collar map). There was a total of 57,536 m of drilling used in the resource model.
Diamond drilling was carried out using HQ and PQ sized equipment with standard tube. For RC drilling, a face- sampling bit (121mm) was used.
Sampling and Sub-sampling
Diamond drill core was sampled as half core at 1 to 2m intervals to geological contacts.
RC chip samples were collected in bags and chip box trays at 1 and 2m intervals. In areas expected to be waste, samples were combined into 2m intervals. RC samples were collected at the rig using rotary splitters.
Sample Analysis Methods
Drill hole samples were sent off site to a recognized and independent analytical laboratories for analyses.
Drill samples collected in 2013 were sent to the SGS laboratory in Ankara. In 2014 and 2015, samples were prepared and analyzed at ALS İzmir, Turkey. All analyses for gold were undertaken via fire assay. A 33 element assay suite including Ag, Cu, Pb, and Zn was completed for each sample by inductively coupled plasma (ICP).
Mineral Resources
Estimation Methodology
Block grade estimation utilized ordinary linear kriging, respecting domain boundaries defining rock types, grade populations and oxidation surface. Modeling parameters were setup to account for extreme grade values, rotation of the mineralized zones and selected mine equipment capability. Reported Mineral Resources contain no allowances for unplanned dilution, or mining recovery.
Mineral Resources Classification
Mineral Resources were classified based on the number of composites used to estimate a block, the average distance between the block center and all the composites used to estimate the block.
Indicated Mineral Resources required blocks to be estimated with four or more composites and having an average distance to the closest composite less than 75 meters. A block was also indicated if the block was within the sulfide mineralized unit with three composites used during the estimation and less than 75 meters to the closest composite. Measured blocks required gold grade estimation using the maximum number of composites and the average distance to the closet composite of 35 meters or less.
Reasonable Prospects of Eventual Economic Extraction
To meet the reasonable prospects of eventual economic extraction criteria for reporting resources, Mineral Resources are tabulated within a floating cone algorithm using a gold price of $1,200/oz, $18/oz for silver,
$3.00/lb copper and $1.20/lb for zinc. Process recoveries and concentrate quality are based on metallurgical testing and judgement regarding the performance of a full scale plant. The metallurgical recoveries used for the floating cone inputs are shown in the table below and vary by grade, process, and concentrate.
Process Recoveries for Floating Cone Input | |
Oxide Ore | |
Gold: 65.921% *(Au grade g/t)^.2314 (87.5% max) | |
Silver: 45% | |
Sulfide Ore | |
Metal Recovery to Copper Concentrate: | Metal Recovery to Zinc Concentrate: |
Copper: 66% | Zinc: 84% |
Gold: 32% | Gold: 0% |
Silver: 17% | Silver: 17% |
Cut-offs vary by processing method. The oxide cutoff grades were based on the income net of refining of $11.70/tonne combining the values of gold and silver. Sulfide cutoff grades for the resource were based on a net smelter return (NSR) of $15.67/t combining the benefits of gold, silver, copper, and zinc.
Processing costs used were $6.92/t in oxide and $10.89/t for sulfide; a G&A cost of $4.78/t of ore processed was also applied. A mining cost of $1.47/t was used as input to the floating cone algorithm. Mineral Resources are reported inclusive of Ore Reserves.
Ore Reserves
Material Assumptions for Ore Reserves
The Ore Reserves were estimated as part of a PFS with all material assumptions being documented in this release and in the JORC Code Table 1 contained in Appendix 2 of this announcement. All operating and capital costs as well as revenue streams were included in the PFS financial model. The PFS finds that the recovery of metals is technically and financially feasible, generating positive returns on plant and infrastructure investments.
Ore Reserves Classification
Ore Reserves are estimated on the basis of detailed design and scheduling of the Gediktepe open pit. The pit boundaries were guided by the results of multiple applications of the floating cone algorithm. The pit shell is estimated using metal values of $1,000/oz for Au, $2.50/lb for Cu, $15.00/oz for Ag, and $1.00/lb for Zn. These metal values were then varied by revenue factors ranging from 0.4 to 1.4 in order to find the preferred pit size and geometry to use as a basis for detailed design.
All of the Ore Reserves are derived from Measured and Indicated Mineral Resources. All Inferred Mineral Resources are considered as waste.
Mining Method
The Gediktepe deposit will be mined by conventional open pit hard rock mining methods. Polimetal currently plans to utilize a contract mining company to move the ore and waste from the mine.
Ore Processing
Oxide ore is processed via heap leaching and sulfide ore is processed via floatation circuit to generate marketable copper and zinc concentrates.
Cut-off Grade
The cutoff grade for material sent to the crusher is $15.16/tonne Net of Smelter for oxides and $14.55/tonne Net of Smelter for sulfides. These are “internal” cutoff grades because they correspond to the sum of the processing and G&A costs. The estimate of processing + G&A costs for oxides was $15.16/tonne and the estimate of processing + G&A costs for sulfides was $14.55/tonne.
Estimation Methodology
Mining dilution was accounted for in the block estimation process and no additional factor was added or applied to the block model.
Oxide gold recoveries have been calculated by an equation dependent on head grade. The maximum recovery for gold is 87.5%. Oxide silver recovery is estimated at 45%. Sulfide recoveries are dependent on the process stream entering either the zinc or copper concentrate. Sulfide gold recovery is estimated at 15.7% in the zinc concentrate and 17.2% in the copper concentrate. Sulfide silver recovery is estimated at 21.5% in the zinc concentrate and 12.3% in the copper concentrate. Sulfide zinc recovery is estimated at 81.5% in the zinc concentrate. Sulfide copper recovery is estimated at 69.2% in the copper concentrate.
Material Modifying Factors
Gold and silver from the heap leach process will be produced in the form of dore and sent to refiners for separation. Sulfide ore will produce gold, silver, copper, and zinc to be sold as either copper or zinc concentrate. The metallurgical testing to date indicates that the gold-silver dore and both concentrates will be of marketable quality.
The project will require the development of a number of infrastructure items in order to operate. The current approach to the project is a combination of oxide heap leaching followed by sulfide flotation. Therefore, both heap leach facilities and tailing storage facilities will be required.
Most of the project area falls into forest land and will need forestry permits from the General Directorate of Forestry and Prime Ministry. The project as shown in the PFS will require a total 379.2 hectares of forest permit area over the life of the mining operation.

Criteria | JORC Code explanation | Commentary |
Sampling techniques | Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. | * The deposit was sampled using diamond drilling and reverse circulation drill holes (RC). * Approximately 38% of the drill holes were RC and 62% were diamond project area through August of 2015. * Diamond drill core was sawn in half and half was sampled at nominal 1 m intervals and split at geological contacts. * RC chip samples were collected in calico bags and chip box trays at 1 and 2 m intervals. Approximately 55% of the RC sample intervals were 2 m long. |
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | * The majority of the drilling is vertical, which intersects mineralization close to perpendicular to the mineralized trend. * Visually observed geological contacts and mineralization vein were used to select the beginning and end of the core sample intervals. * Sampling starts five meters above the mineralization in hanging wall rock and ends five meters below the mineralization in footwall rock. * The core was sawn in half, one half was sent to the laboratory for assaying and the second half stored at the core logging facility at the camp area. * RC chip samples were collected using a riffle splitter with a representative sample sent to the lab for assay. * 255 of the 487 drill holes have down hole survey measurements. | |
Aspects of the determination of mineralization that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralization types (eg submarine nodules) may warrant disclosure of detailed information. | * Drill hole samples were sent offsite to recognized and independent analytical laboratories for analyses. * Drill samples collected in 2013 were sent to the SGS laboratory in Ankara.

For Cu, Zn and Ag there was a total of 244 standards submitted out of 31,495 total assays. * Overall relative bias for the CRMs is within an acceptable 5%. Of the 1,572 submitted standards for gold, about 2% are more than 10% different from the original value. * A total of 1134 blank samples were used, resulting in an inserted rate of 1 in 28. Blank sample results do not indicate any sample contamination issues. * Gold assay results are acceptable for use in supporting Mineral Resource estimates. Limited QA/QC exists to support Ag, Cu, Pb or Zn assays. |

The assumptions used for any reporting of metal equivalent values should be clearly stated. | * Resources are reported by metal - gold, silver, copper and zinc. | |
Relationship between mineralization intercept lengths | These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). | * Mineralization dips to the northwest, on average 20 degrees. Aside from a few angled holes, drilling is vertically oriented. Mineralized intercept lengths are slightly longer than true mineralized widths. |
