Alacer Gold Announces a 117% Increase to the Ardich Indicated Mineral Resource Located in the Çöpler Mining District

639,000 Indicated and 96,000 Inferred Gold Ounces

TORONTO, April 03, 2019 (GLOBE NEWSWIRE) -- Alacer Gold Corp. (“Alacer” or the “Corporation”) [TSX: ASR and ASX: AQG] is pleased to announce the addition of 345,000 contained gold ounces to the Indicated Ardich Mineral Resource located approximately 6 kilometers (km) northeast of the Çöpler Gold Mine. The updated Mineral Resource estimate consists of predominantly oxide ore, with some sulfide ore, totaling:

  • Indicated Mineral Resource of 639,000 ounces of gold at an average grade of 1.50 Au g/t (13.2MT)
  • Inferred Mineral Resource estimate of 96,000 ounces at an average grade of 1.16 Au g/t (2.6MT)

Rod Antal, Alacer’s President and Chief Executive Officer, stated, “Given its potential and near-term development optionality, Ardich has become the highest priority development target in Alacer’s portfolio. The Resource continues to grow and remains highly prospective, with the potential to add near surface ounces to our production profile within the next two to three years. With the receipt of the permits, we plan to start step-out drilling next week to test the extent of the mineralization to continue to grow the resource.”

The updated Mineral Resource demonstrates the deposit’s growth and continued upside potential. The Mineral Resource estimate is based on 100 diamond core drill holes with assays completed through February 2019. The size of the deposit is expected to grow as new step-out drilling is completed.

Opportunities exist to process Ardich oxide ore at the existing Ҫӧpler oxide plant facilities or to construct standalone processing facilities at Ardich. An engineering study will be completed in 2019 for a ~20Mt incremental expansion of the Çöpler heap leach pad. The conceptual design for the heap leach pad expansion and the stability study have been completed to a sufficient level for the EIA amendment to be prepared for submission. In addition, options for standalone facilities and heap leach pad facilities of varying size (some >50Mt) have been conceptualized should the Ardich deposit grow to the full extent of the mineralized target. Opportunities also exist to process Ardich sulfide ore at the newly constructed Çöpler sulfide plant facilities.

Highlights

  • Ardich is adjacent to the Ҫöpler Mine and processing facilities with an existing access road connecting the nearby Ҫakmaktepe operations.
  • The Mineral Resource is predominately oxide ore.
  • Exploration continues at Ardich and mineralization remains open in all directions.
  • Permits have been received to allow step-out drilling in the most prospective areas to the southeast of the Ardich Mineral Resource.
  • The mineralized target now extends over 2 km.

Note:  Metal price assumptions were $1,500/oz for gold. Mineral Resources are shown on a 100% basis. Greater than 99% of the Mineral Resource is located on the Alacer owned 80% ground, with the remainder of the mineralization within the 50/50% ownership boundary. Heap leach processing costs include site support and sustaining capital, and are estimated to be ~$9/tonne ore, based on reagent consumption tests and benchmarking with the nearby Ҫöpler Mine. Sulfide processing costs include site support and sustaining capital, and are estimated to be ~$40/ tonne ore, based on preliminary floatation test results and benchmarking to the nearby Ҫöpler sulfide plant. Pit slope angles vary from 35°- 40° IRA dependent azimuth. The average sulfur grade for the sulfide resource is 2.1%. Mineral Resources have demonstrated reasonable prospects for eventual economic extraction by falling within an economic pit shell, using the listed design parameters. Rounding differences will occur.

The Ardich gold property is a listwanite-dolomite hosted gold replacement deposit with mineralization occurring along thrust zones between listwanite, ophiolites, hornfels and limestones. Mineralization and alteration extend in a NW-SE direction, parallel to major structures controlling both mineralization and block rotations. Gold grades increase at dolomite-listwanite contacts and within quartz vein rich listwanites. The mineralization is predominantly oxide with sulfide mineralization confined to pyrite rich jasperoid bodies. Based on available drill data, the main mineralized zone appears tabular and almost flat lying.

The Mineral Resource estimate was based on a 3D geological solids model developed within constraining fault blocks. Lithological units are shifted within each fault block. Gold mineralization was modeled along the geologic contacts and fault zones. Mineralized zones were used to generate a block model estimate of the deposit mineralization. Model construction used drill data and surface mapping through February 1, 2019. The block model contains estimated grades for gold and sulfur. Ardich contains trace occurrences of silver and copper. These two elements are not present to a level necessary for grade estimation and inclusion into pit shell economics.

Conventional heap leach processing recovery estimates are based on the most current information available through three phases of test work, including column leach testing. Metallurgically, the deposit has been divided into two zones, Main and East, as well as being divided by lithology and sulfur grade. The East Zone has initially shown lower recoveries under typical heap leach conditions than the Main Zone. Additionally, ores with sulfur grades up to 1% and potentially up to 2%, have been shown to be amenable to conventional heap leaching. Metallurgical recoveries vary by rock type, zone, and sulfur content; and range from 40% to 73% with a resource average near 68%.

Initial floatation test work has been completed for sulfide material from which a gold concentrate will be produced in addition to cyanide leach recovery from tailings. Sulfide material considers ores with sulfur grades greater than 2% and those which are not amenable to heap leaching. Metallurgical recoveries are estimated to range from 73% - 77% with costs based on completed studies to date and industry benchmarking.

A pit shell was evaluated using Whittle, based on $1,500/ounce gold price for the Ardich Mineral Resource estimate. Inputs for the pit shell generation include the most current information available for geotechnical conditions, operating costs, reagent consumptions, and metallurgical recoveries.

All but two holes have been drilled within Alacer’s 80% owned and managed licenses. Less than 0.2% of the resource is on the Kartaltepe 50% ground. The resource shell used to demonstrate reasonable prospects for eventual economic extraction crosses the Kartaltepe (Alacer 50%) license boundary due to pit slope requirements needed to reach mineralization residing on Alacer ground.

Ardich Resource Sensitivity by Nested Shell

Mineral Resource pit shell optimization was completed using Whittle with the inputs as listed above in the resource table. Internal cut-off grades for oxide ore range from 0.30 – 0.50 g/t Au and sulfide ore is set at 1.0 g/t Au. Cut-off grades were calculated using a $1,500/oz gold price, processing recoveries, and processing costs as inputs.

Drill Information

Assay results were available for 100 holes totaling 15,590.5 meters. These holes were used to define the Mineral Resource estimate. In addition,

  • Mining Rock Mass Rating geotechnical logging was added for the majority of the Ardich core holes;
  • Step-out drilling will start in Q2 2019, testing extensions to known gold mineralized trends;
  • Environmental baseline study commenced in 2018 and will continue through 2019; and
  • Metallurgical testing will continue to evaluate sulfide processing options.

Next Steps

This year, exploration activity at Ardich will focus on determining the extent of the mineralization. This will include both exploration drilling used to define mineralization and drilling to obtain samples needed for continued metallurgical studies. Geotechnical logging will be studied to determine if adjustments are needed to the current slope angles. Concurrently, work is underway to determine options for a starter pit in the known mineralization and advancing requirements for permitting and project development.

Metallurgical Test Work

A three-phase metallurgical testing program was conducted by McClelland Laboratories, Inc. (Sparks, NV, USA), under the guidance of Metallurgium. The first phase comprising of bottle roll cyanide leaching tests and floatation tests have been completed. The second phase of work comprising of column leach testing was finalized in August 2018. The third phase (additional column leach and floatation testing) commenced in June 2018 and continues at this time.

The listwanite, dolomite and jasperoid ore types submitted for Phase I testing indicate that these materials are potentially suitable for processing by heap leaching at a crush size of 80% passing 12.5mm. Based on Phase I testing, the 72-hr bottle roll cyanide leach gold extractions were generally in the range of 40-80% (mid-range ~60%) for the samples tested. Expected cyanide and lime consumptions were in the low-moderate range for these ore types. The cataclastite ore type was determined to be unsuitable for processing by either heap leaching or agitated tank cyanide leaching due to high sulfur content. Floatation tests of cataclastite ore indicate a concentrate recovery of 70% with a tailings leach recovery of 25%. Overall recovery is estimated at 73%.

The samples for the Phase II testing were obtained from fifteen drill holes (AR10-AR24 inclusive), representing a portion of the exploration program that had been completed at the time. The samples were subsequently composited into seven composite samples based on a detailed metallurgical testing program developed by Metallurgium in conjunction with Alacer and McClelland Laboratories. In addition, six samples of whole core, one representing each major ore type, were submitted for comminution testing.

There is a strong relationship between gold extraction and sulfur grade in the Ardich deposit. Gold extractions are generally good when the sulfur grade is less than 1%. Material containing <1% sulfide sulfur is expected to be suitable for heap leaching. Material containing >1% and <2% is potentially suitable for heap leaching.

Ardich Phase III metallurgical test work is ongoing and details of sampling are given in Tables 2,3 &4.

Results of the Phase II and III column leach testing revealed that agglomeration will not be required and there were no issues with the materials related to permeability. The results of the Phase III bottle roll leach tests (at the 80% <12.5mm crush size) on the 6 composite samples show a very similar trend to the Phase I results in terms of gold extraction versus sulfide sulfur content. The Phase III bottle roll samples at 72 hours with <1% sulfide sulfur yielded average gold extraction of 55.5% compared to 59.6% for the Phase I samples with <1% S2-. Floatation tests on Jasperoid and dolomite indicate a concentrate recovery of 44% with a tailings leach recovery of 63.5%. Overall recovery is estimated at 77%.

Summary for the purposes of ASX Listing Rule 5.8

Please refer to the JORC Code Table 1 contained in Appendix 2 of this announcement for information relating to the estimates of Mineral Resources for the Ardich Project. A copy of which can be found on www.sedar.com, the Australian Securities Exchange and on our website www.alacergold.com.

Geology and Geological Interpretation

The Ardich deposit is characterized by development of gold mineralized listwanite and dolomite formations within a northwest-southeast structural zone. The gold mineralization is closely associated with low angle thrust zones between listwanites, dolomites and ophiolites that are intruded by a series of dykes. The mineralization is related with crystalline and chalcedonic quartz veins within the brecciated and silicified listwanite and dolomite bodies. The mineralization is predominantly in the form of oxide with sulfide mineralization confined to limited pyrite rich jasperoid bodies. The latest drill data and three-dimensional model indicates the main mineralized zone appears to be tabular and almost flat lying.

Drilling Techniques

Exploration drilling and sampling at Ardich utilized surface PQ and HQ triple-tube diamond core drilling. Core was sampled predominately in 1.0m lengths as sawn half core in competent ground or hand split if in clay or broken fault zones. Overall, Ardich core recovery is very good with a mean recovery of 92.8%. Review of the core photographs supports the high recovery percentage. No reverse circulation drilling has occurred to date. The use of scissor drilling has allowed sampling of mineralized zones from different orientations. Majority of the drilling was completed at an angle of 60 degrees with varying directions/azimuths. Scissor drilling creates variable sample orientations not easily viewed in two-dimensional sectional plots.

The data set used to construct the geologic and resource model contained a total of 100 holes with geologic logging and assay results complete. Total drill meters equaled 15,590.5. Alacer drilled the diamond core holes between August 2017 and December 2018.

Sampling and Sub-sampling

The Ardich drilling program started in 2017. Diamond drill core is sampled as half core at 1m intervals. The samples were submitted to ALS Global laboratories in Izmir, Turkey for sample preparation and analysis which is an ISO/IEC 7025:2005 certified and accredited laboratory. Bureau Veritas (Acme) laboratory, Ankara is being used as for umpire check sample analysis. Gold was analyzed by fire assay with an AAS finish, and the multi-element analyses were determined by four acid digestion and ICP-AES and MS finish. For gold assays greater than or equal to 10 g/t, fire assay process is repeated with a gravimetric finish for coarse gold. Alacer's drill and geochemical samples were collected in accordance with accepted industry standards. Alacer conducts routine QA/QC analysis on all assay results, including the systematic utilization of certified reference materials, blanks, field duplicates, and umpire laboratory check assays.

Data Verification

External review of data and processes relating to Ardich was completed by independent Consultant Dr. Erdem Yetkin, P.Geo. in November 2018 and February 2019. There were no adverse material results detected and the QA/QC indicates the information collected is acceptable, and the database can be used for further studies. The data in the database has been sufficiently validated to support Mineral Resource estimation.

Metallurgical Test Work

A three-phase metallurgical testing program was conducted by McClelland Laboratories, Inc. (Sparks, NV, USA), under the guidance of Metallurgium, comprised of bottle roll cyanide leaching, column leach, and floatation tests.

Mineral Resource

Estimation Methodology

For the Ardich Mineral Resource, mineralized grade shells were used as defining boundaries which followed the geological interpretation of fault blocks and contact lithologies. In the creation of mineralized domains, a minimum mining width of 5m was used based on anticipated open pit mining methods using a 5-meter bench height and 5-meter grade control sampling.

The estimation was controlled by the interpreted mineralized domains, with each domain estimate using only samples contained within that domain. Outside the mineralized domains a ‘mineralized waste’ estimate was completed to include surrounding grade in the model.

Ardich was estimated using Inverse Distance Cubed (“ID3”). ID3 is a linear estimation technique applied to gold and sulfur mineralization. Nearest Neighbor and Ordinary kriging estimates were used as comparison estimates to the ID3 method.

Model Verification

Gold estimates were validated against alternate interpolation methods. Estimated grades were compared to a nearest neighbor model to check for global bias. Swath plots were used to check for a local bias. The estimated gold grades in the model were compared to the composite grades by visual inspection in plan views and cross sections. Composite samples were queried by domain to confirm proper sample flagging.

Mineral Resources Classification

Mineral Resources were classified based on a drill spacing study and observed continuity of geology and mineralization. Indicated Mineral Resources should be known within +/- 15 percent with 90 percent confidence on an annual basis and Measured Mineral Resources should be known within +/- 15 percent with 90 percent confidence on a quarterly basis. No blocks were classified in the Measured category.

Drill hole spacing for support of classification of Inferred Mineral Resources could be obtained when sample spacing was 70m by 50m. For Indicated Mineral Resource classification, the drill hole spacing reduced to a 35m by 35m spacing. Appropriate drill hole pattern spacing selection was based on the belief that the mineralization is structurally controlled, mineral continuity varies within each domain and adequate data quality has been achieved.

Reasonable Prospects of Eventual Economic Extraction

To meet the reasonable prospects of eventual economic extraction criteria, Mineral Resources are tabulated within a Lerchs-Grosmann (LG) optimization shell generated using a gold price of $1,500/oz., and metallurgical gold recoveries that vary from 40% to 73% for oxide material and 73% to 77% for sulfide material.

Cut-off Grade

Mineral Resources were tabulated using multiple cut-off grades due to variable recoveries and based on gold price only. Cut-off grades are calculated based on the equation:  Xc = Po / (r * (V-R)); where Xc = Cut-off Grade (g/t), Po = Processing Cost of Ore (USD/tonne of ore), r = Recovery, V = Gold Sell Price (USD/gram), R = Refining Costs (USD/gram). Cut-off grades vary from 0.30 – 0.50 g/t for oxide and 1.10 – 1.15 g/t for sulfide.
