Alacer Gold Announces Further Exploration Results for the Copler District
TORONTO, July 21, 2016 (GLOBE NEWSWIRE) -- Alacer Gold Corp. (“Alacer” or the “Company”) (TSX:ASR) (ASX:AQG) is pleased to announce drilling results through May 31, 2016 from the Company’s 2016 Çöpler District exploration program in Turkey. Drilling results are from an additional 17,361 meters of drilling at the Çakmaktepe North prospect (formerly known as Yakuplu North) approximately 5 km east of the Çöpler Mine. These results are in addition to drill results released on December 9, 20151 and March 31, 20161.
Rod Antal, Alacer’s President & Chief Executive Officer, stated, “We’ve taken a disciplined approach to our exploration program and have focused on the discovery of satellite leachable oxide mineralization that has the potential to provide supplemental feed to the existing Çöpler heap leach pad. This latest round of Çakmaktepe North drill results represent a significant step forward in progressing this objective and the results continue to confirm the potential to add oxide production within the next two years at Çöpler.
The 2016 program includes infill drilling with the aim to validate data to support the resource estimation for a maiden resource later this year. With the mineralization at Çakmaktepe North still open in all directions, the maiden resource will only include the drilling for a portion of the mineralization. We have drilled over 30,000 meters at Çakmaktepe North and still have nine drill rigs on site to progress this highly promising exploration prospect. In expectation of advancing this prospect, the permitting process is underway.”
KEY HIGHLIGHTS
Çakmaktepe North is the largest of six current gold prospects within a 5 km to 7 km proximity of the existing Çöpler Mine infrastructure. Initial and follow-up results from exploration drilling at Çakmaktepe North were provided in press releases dated December 9, 20151 and March 31, 20161. The drilling conducted between January 1 to May 31, 2016 included infill drilling and continues to expand on the initial 2015 discovery. The Çakmaktepe area contains a network of structures allowing for gold mineralization to occur within multiple lithologies. The mineralization style is similar to the Çöpler Deposit and is expected to be processed through the existing crushing and agglomeration circuit and stacked on the existing heap leach pad facility at the Çöpler Mine.
- Based on the results to date, the Çakmaktepe prospect will continue to advance in 2016 with the intention of releasing a maiden mineral resource later this year.
- The mineralized system is currently open in all directions, providing the potential for additional mineralization.
- Initial design work for the proposed haul road to Çöpler has been undertaken.
- The permitting process is underway.
DRILLING HIGHLIGHTS
Drilling from the Çakmaktepe North prospect in the Çöpler District in central eastern Turkey has continued to define near-surface leachable oxide mineralization.

ÇÖPLER DISTRICT 50/50% (KARTALTEPE JV) EXPLORATION RESULTS
Çakmaktepe North
Çakmaktepe North is a 2015 discovery that was identified from rock chip and soil sampling in early 2014. A drilling program commenced in June 2015 to define mineralized gossan on a 50m x 40m spacing over a strike length of 700m. As of May 31, 2016, a total of 29,744 meters of reverse circulation (“RC”) and diamond core drilling (“DDH”) has been completed from 174 holes. This is the third exploration press release for Çakmaktepe North.
The Çakmaktepe North mineralization is contained within shear and thrust hosted jasperoid, iron rich gossan, brecciated limestone and altered metasediments. There are multiple controls on mineralization with strong epithermal textures and associated structural overprints. The main body of mineralization is associated with a subvertical shear zone referred to as the ‘Main Shear’. The Main Shear varies in width from 5m to 40m, has been defined to a depth of 200m to 250m from surface, and dips at approximately 70 degrees to the east. Surface mapping and sampling have defined the mineralized extent of the shear as being over a kilometer in length, of which 700m has now been drill tested.
Results and outcomes presented in this release are from 17,361 meters of RC drilling and DDH from 107 holes completed between January 1 and May 31, 2016.
Drilling to date has not closed-off the mineralized system. Infill drilling to a spacing required for classification as a mineral resource estimate is in progress. The 2016 resource development strategy has focused on infilling and extending down-dip the northern 450m strike extent of the shear zone. Priority has been placed on validation of grade, mineralization distribution and continuity in the areas of highest gold grades.
Of the 107 holes completed in 2016, 18 were specifically designed as large diameter scissor holes drilled into the mineralization in the opposite direction to the current drill pattern. All 18 holes validated the accuracy of the geological model, replicated mineralization distribution and grade, as well as provided samples for metallurgical test work in Q2 and Q3 of 2016.
Of the 107 holes completed, there were 4 groundwater monitoring boreholes drilled as part of resource development, of which 2 intercepted significant mineralization in new areas peripheral to potential pit designs. All four holes were equipped with piezometers as part of a program to develop a hydrogeological model for permitting.
Since the Press Release issued on March 31, 2016 there has been significant evolution of the geological understanding of Çakmaktepe North through step-out and infill drilling. Although still the major trap for mineralization, the ‘Main Shear’ intersects a shallow thrust on its western footwall which is also mineralized. The structure is referred to as the ‘Footwall Thrust’ and is now recognized as a potential contributor of new gold to the Çakmaktepe North prospect. The Footwall Thrust is still to be fully drill tested, but to date extends over 150m to the west from its intersection with the Main Shear, has a strike of 350m and varies in thickness from 5m to 15m. Mineralization within the Footwall Thrust is hosted within iron rich jasperoid, gossan and underlying brecciated limestone. The Footwall Thrust defines the contact between overlying ophiolite and limestone, occurring within 150m of surface.
In the process of extending the down-dip extent of high grade Main Shear mineralization, drilling in 2016 has identified metasediments forming the hanging wall to the Main Shear to also be mineralized. Grade enhancement occurs where the metasediments are proximal (within 50m) of the Main Shear and intersected by mineralized diorite dykes. The metasediment forms a distinct hanging wall domain with ore type characteristics and grades similar to metasediments within the Ҫöpler Main pit.
Extensive development drilling continues to close the drill spacing in the high grade area of mineralization from 50m x 40m to 25m x 20m to a depth of 250m below surface for mineral resource estimation in 2016. Drilling from June to September 2016 will also focus on extending the mineralized Main Shear and Footwall Thrust 150m to the north.
Drilling after October 2016, will focus southwards along strike of the Çakmaktepe North prospect to test whether shear hosted mineralization at the Çakmaktepe Main target can be connected to the Çakmaktepe North prospect. The Çakmaktepe Main prospect hosts recent small-scale mining where iron rich gossan was previously extracted by another company. Residual Çakmaktepe Main gossan stockpiles report gold values of >1.0g/t Au.

Technical Procedural Information
Exploration drilling and sampling in Turkey utilized dominantly surface HQ and HQ3 triple-tube diamond core and 5 ¼ inch diameter RC drilling methods. Reverse circulation cuttings were sampled on 1.0m intervals and core was sampled systematically in 1.0m lengths as sawn half core in competent ground or hand split if in clay or broken fault zones. All drill sample assaying was performed by the SGS Ankara commercial assay laboratory in Turkey. Samples were analyzed for gold by Fire Assay off a 30 gram charge with an AAS finish, and analyzed for silver, copper, lead and zinc using a four acid digest ICP-AES method. Gold assays over 3g/t Au were automatically re-assayed by Fire Assay with a gravimetric finish. For silver, copper, lead and zinc assay results above the ICP-AES upper detection limits, samples were re-analyzed using a four acid digest with HCI leach and AAS finish. Quality Assurance/Quality Control measures included the insertion and continual monitoring of standards, blanks and duplicates inserted into the sample stream. QA/QC samples represent approximately 10% of all assay results received. Exploration and drilling results are reported as downhole drilled thicknesses. Drill hole significant assay intervals were calculated using a minimum downhole length of 5m @ >1.00g/t Au (body of text) or 2m @ >1.00g/t Au (Appendices). Grades were calculated using length weighted average sample grades for the interval. No top cut was applied.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
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. | - Diamond drill core was sampled as half core at 1m intervals or to geological contacts. - RC chip samples are collected in calico bags (3-5kg) for analysis and representative sub-samples placed into chip box trays at 1m intervals for logging. Reject samples are collected in PVC bags and stored in a bag farm for 6 months in case need arises for relogging, duplicate sampling, metallurgical sampling and follow-up QAQC. |
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | - To ensure representative sampling, diamond core is marked considering mineralization intensity and veining orientations then sawn and half core sampled. - Where possible all diamond core is oriented using 2IC Ezy-Mark or Reflex ACT II systems and collected in HQ triple tube splits pumped out with water. PVC pipe is inserted into areas of core loss marked with interval of loss. PVC pipe is cut to equivalent length of core loss and placed into core trays. Majority of holes are downhole surveyed using a MEMs Gyro to ensure accurate location of all samples within the bore hole. - RC chip samples are collected at 1m intervals using a side mounted rotary cone splitter. All samples are weighed using digital scales with weights recorded and used to determine sample representivity. The scale is tared before each measurement. All weights are recorded onto paper and transferred to the geological database. |
Criteria | JORC Code explanation | Commentary |
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 samples from which 3 kg was pulverised to produce a 30 g charge for where there is coarse gold that has inherent sampling problems. Unusual warrant disclosure of detailed information. | - Diamond Core samples are submitted as 1m half core to SGS Ankara laboratory for standard industry analysis i.e. samples crushed and split to 3kg, pulverized and subsampled to 250g and fire assayed using a analysis for 36 elements using a four acid digest and ICP-ME (OES) samples. Over limit precious and base metals are reanalyzed by AAS. applicable, Cyanide leachable gold is determined using a hot ‘Shaker analysis is completed where samples return total sulphur values >2%. All samples are weighed on receipt, dried, reweighed and moisture content determined. Crushing and Grind size checks are completed at all stages of sample reduction. - RC samples go through the same assay process at SGS Ankara, with initial samples submitted being 3-5kg RC chip samples that are crushed and then split to 3kg before pulverizing. | |
Drilling Techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). | - Diamond drilling was mainly carried out with HQ and HQ3 triple tube. Precollars, metallurgical and difficult holes were completed with PQ and PQ3 triple tube. NQ was used in situations where, due to difficult ground conditions, the best option was a reduction in core size to NQ. Majority of holes were downhole surveyed by MEMs Gyro provided and maintained by Wellforce International. At times when MEMs Gyro was not available a Reflex Multi-Shot tool was used in place of Gyro. Core orientation was completed using the 2IC Ezy-Mark orientation system, with use of the Reflex ACT II tool for orientation when Ezy-Mark kits not available. - Çöpler District: RC drilling was completed with a nominal 5.25 inch face sampling hammer. Majority of holes were downhole surveyed by MEMs Gyro provided and maintained by Wellforce International. A Reflex Multi-Shot tool was used when the MEMs Gyro was not available. |
Drill Sample Recovery | Method of recording and assessing core and chip sample recoveries and results assessed. | - Diamond Core - o All diamond core is measured and reconciled against core blocks, end of hole depth and drillers run-sheets. o Intervals of visual and calculated missing core are recorded in the sampling spreadsheet and geological database. PVC of equivalent length to missing core interval is inserted as a visual marker of core loss. |
Criteria | JORC Code explanation | Commentary |
o Core recovery is calculated on a per metre basis of recovered core and entered into the database as a percentage. In general, core recoveries are between 80 – 90%, reflecting strongly sheared, brecciated, altered and in areas of limestone, karstic ground being drilled (cavities). - RC Samples - o Both primary and residual samples are weighed to document sample recovery and determine recovery percentages against nominal expected sample weights. o The rotary cone sampling unit is adjusted as required to maintain a representative sample volume being collected by a 5.25 inch face sampling hammer. o All weighing is completed in the field using a digital scale with tare function. o Duplicate samples, standards and blanks are inserted into sample stream to achieve 10% QAQC coverage of sampled material. | ||
Measures taken to maximize sample recovery and ensure representative nature of the samples. | - Diamond Core - o Use of HQ3 and PQ3 triple tube with splits to collect maximum intact core. o Inner tubes pumped out with water to prevent core loss and breakage. o Use of bentonite commenced with Çakmaktepe North drilling to improve core recovery through ‘caking’ of more porous and poorly consolidated lithologies. o Drilling of short core runs (1.5m). - RC Sample - o Monitoring of sample weights and adjusting rotary cone sampling system accordingly to ensure correct weight of primary sample split. o Monitoring of reject sample weight versus expected nominal achievable 20kg reject. Advising driller to modify drilling speed and or hammer rate to produce coarser sample and less fines. o Monitoring of outside return to flag excessive fines loss. o No wet sampling. o Clearing of sample equipment by air burst every metre drilled before progressing to next metre sampled. o Manual cleaning of sampling cyclone and rotary cone splitter at end of every hole and during drilling as required to prevent contamination. |

Sub- Sampling Techniques and Sample Preparation | If core, whether cut or sawn and whether quarter, half or all core taken. | - Diamond Core – o Exploration and Resource diamond core is half core sampled using a manual drop saw to cut to one side of the bottom of core line (where present in competent ground). o Half-core with bottom of hole line is retained in the tray. o PQ core is used for metallurgical sampling. ¼ core is used for initial assay. ½ core is dispatched in 1m intervals for metallurgical compositing and testing, ¼ core is retained in tray. o HQ triple tube core is used for geotechnical drilling, 10cm complete core segments are extracted for external laboratory testing (UCS, DS). Core block with sample details is left in core tray. o As with geotechnical core, select sampling for petrology is collected from ½ core and a core block with details of sample is inserted into core tray. o Soft (clay), poorly consolidated (regolith, oxide) and fragmental samples (fault, shear, breccia materials) are hand split into 1m ½ core samples. |
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. | RC samples are drilled using a face sampling hammer with samples collected via a rig side-mounted cyclone and rotary cone splitter. Samples are collected dry. Occasional moist samples are collected at top of sample intervals following 3m rod changes. Samples remain dry during metre by metre blow-out of contaminants in cyclone and cone splitter. Duplicate samples are collected using a 50/50 Jones riffle splitter at the drill rig. | |

Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. | - RC and diamond sampling have 5% of total submitted samples as field duplicates. With RC samples, a field duplicate is collected through use of a Jones riffle splitter to achieve a 50% primary sample split. With diamond core, quarter core repeats are selected and submitted post-primary sample submission. A further 5% of samples submitted are “blanks” and “standards” designed to check on laboratory performance during assay (accuracy & precision). Laboratory QAQC and field duplicates combined represent 10% of material assayed and analysed. - Results to date are within expected industry tolerances for duplicate and laboratory performance. There is no material bias to report. | |
Whether sample sizes are appropriate to the grain size of the material being sampled. | - Sample sizes are considered appropriate to correctly represent the gold mineralization based on: the style of mineralization, the thickness and consistency of the intersections, the sampling methodology and assay value ranges for gold. | |
Quality of Assay Data and Laboratory Tests | The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. | - The fire assay gold analyses undertaken are considered a total assay method. Fire assay gold analysis is an appropriate assay method for this type of deposit. - Multi-element analyses of silver, copper, lead and zinc undertaken by four acid digestion via ICP-AES are considered total assay methods except where they exceed the upper detection limit. - In cases where samples are overlimit they are re-assayed using a four acid digest with HCI leach, and AAS finish. These assay methods are considered to be total. - For gold assays greater than 3g/t, the fire assay process is repeated with a gravimetric finish for coarse gold. This is a total assay method. - Cyanide leach analysis is completed to determine potential gold leach recoveries when compared against total contained gold. The cyanide leach analysis is a partial analysis method. |
For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. | - TerraSpec 4 desktop ASD PIMA (Portable Infrared Mineral Analyser) spectrometer for detection of alteration (clay mineralogies) was used. The machine is serviced and calibrated annually and used in conjunction with TSG software for conversion of spectral data to mineral data. PIMA is used on all RC chip samples to create clay and mineralogy models for correlation against alteration logging and geochemically determined lithologies. |

Criteria | JORC Code explanation | Commentary |
Drill hole Information | A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. | - The locations and mineralized intersections for all holes completed are reported in Appendix 1 of this release. |
Data Aggregation Methods | In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. | - Exploration results are reported as length weighted averages of the individual sample intervals. - No high-grade cuts have been applied to the reporting of exploration results. |
Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. | - Zones of particularly high-grade gold mineralization have been separately reported in Appendix 1. | |
The assumptions used for any reporting of metal equivalent values should be clearly stated. | - No metal equivalent values have been used. | |
Relationship between Mineralization Widths and 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’). | - At Çakmaktepe North the mineralization strikes ~NW-SE with a dip of ~80 degrees to the NE. Drilling is to the SW at 90 degrees to strike with drilling intercepts representing 40 to 60% of true width. |
Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. | - Relevant diagrams have been included within the main body of text. |
Criteria | JORC Code explanation | Commentary |
Balanced Reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. | - All exploration results from these drilling programs have been reported, inclusive of drill holes having no significant results. |
Other Substantive Exploration Data | Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. | - Metallurgical testing is still to be completed for Çakmaktepe North but based on similarity of ore to adjacent Çakmaktepe East and Southeast deposits, the oxide mineralization is anticipated to have similar recovery characteristics to Çöpler Deposit ores and could be processed through the Çöpler processing plant (heap leach). |
Further Work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. | - Çakmaktepe North is an active growth project with scale of mineralized system, strike and depth extent, and grade continuity currently being defined. Multiple diamond drill rigs and an RC rig worked through 2015 to complete an initial 50 x 40m pattern of drilling across a 700m strike extent of mineralized shear. - Current drilling in 2016 is progressing to reduce the initial 50 x 40m pattern of drilling to 25 x 20m for resource estimation using 8 diamond and 1 RC drill rig. - Current drilling at Çakmaktepe North is also stepping-out to the north and down-dip of existing mineralization to test for mineralization extension. - Geotechnical drilling is planned in the next phase of 2016 drilling as part of the resource development process to progress the deposit to a resource and reserve. |
