Alacer Gold Corp. [TSX: ASR) (ASX: AQG] is pleased to announce additional positive drill results for the Ardich gold prospect. In addition to the previously announced 43 diamond core drill holes1, a further 20 diamond core drill holes are being reported, with a majority intersecting predominantly oxide gold mineralization including holes:
Previously announced holes include1:
Based on the 63 diamond core drill holes totaling 9,984.9m, gold mineralization is open in all directions and the new holes defined additional extension of the mineralization to the north and east of the known mineralized zone. Drilling to date has been primarily on 80% Alacer owned licenses (all holes except the end of two holes, AR27 and AR33).
Alacer is in the process of preparing an interim resource estimate which will be released in late 2018. This interim resource will be based on the data from the first 55 diamond core drill holes only due to the timing of the resource report preparation, and thus will only represent a portion of the expected final Ardich resource. The objective of the ongoing exploration program is to first define, by step-out drilling, the extent of the mineralization. Once the mineralized system dimensions and geology is better understood, a more comprehensive infill drilling program will be started with the aim of defining an expanded resource and a reserve estimate. While drilling continues at Ardich (currently drilling hole AR91), additional Forestry permits are required to begin further step-out drilling into the most prospective areas to the southeast. Concurrently, work has started on the permitting process as well as metallurgical testing, with the initial results indicating the oxide ores are suitable for processing via heap leaching.
A recent scoping study to determine the optimal pathway for the expansion of the heap leach oxide processing capacity in the Çöpler District identified various options (at both Ardich and Çöpler) for standalone facilities and heap leach pads of varying size (some >50Mt), along with a low cost incremental expansion option at Çöpler (~20Mt of additional heap leach capacity at a cost of ~$15M). These options provide pathways to both accelerated low-cost, near-term development of Ardich or other Çöpler District prospects, as well as options for a new separate mine development should the Ardich deposit grow to the full extent of the mineralized target. A feasibility study will be completed in 2019 for the ~20Mt incremental expansion of the Çöpler heap leach pad.

The Ardich gold prospect is characterized by development of gold mineralized listwanite and dolomite formations in a 800m x 600m target area within a northwest-southeast structural zone (Figure 2). The gold mineralization is closely associated with low angle thrust zones between listwanites, dolomites and ophiolites that are intruded by a series of microdioritic 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 and is confined to limited pyrite rich jasperoid sections. Based on the latest drill data, the main mineralization zone appears to be tabular and almost flat lying.
Alacer drilled 63 diamond core drill holes totaling 9,984.9m between August 2017 and mid-September 2018. The company announced drill results of the first five holes on December 18, 2017, including AR04 with 84.9m averaging 1.79 g/t gold and including 24.7m averaging 4.53 g/t gold. Results of an additional 13 diamond core drill holes were released on February 26, 2018, and all holes have intersected predominantly oxide mineralization with some impressive grades, including hole AR09 with 67.7m averaging 4.08 g/t gold. In addition to these previously reported 18 holes, Alacer announced results of 25 holes (AR19-AR43) on July 25, 2018. Key results include hole AR41 with 50.2m averaging 3.01 g/t gold from 43.4m depth (including subinterval of 7.9m @ 8.81 g/t gold) and hole AR31 with 68.6m averaging 2.21 g/t Au from 36m depth (including 17m @ 5.5 g/t Au).
Alacer is continuing the drilling program in Ardich with two diamond drill rigs and has completed 20 diamond core drill holes totaling 2,641.8m between July and mid-September 2018 (AR44-AR63). These additional holes improved the northwest and eastern extension of the gold mineralization defined by the earlier 43 diamond core drill holes. Drill holes AR47, AR48, AR51, AR52 and AR53 are located to the east of the known mineralized zone and have intersected significant gold mineralization underneath barren ophiolites. This demonstrates possible continuation of gold mineralization to the east of the prospect covered by ophiolites that do not have any surface geochemical reflection. The gold mineralization remains open in all directions. Additional Forestry permits are required to undertake further step-out drilling into the most prospective areas to the southeast. These are expected soon.
All drilling outlined below was diamond core drilling using either HQ (63.5mm in diameter) or PQ (85mm in diameter) core sizes.

Technical Procedural Information
Sampling, Assaying and QA/QC
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 of a 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 10g/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. External review of data and processes relating to the prospect have been completed by independent Consultant Dr. Erdem Yetkin, P.Geo. in October 2018. 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.
Metallurgical Test Work
A three-phase metallurgical testing program is being conducted by McClelland Laboratories, Inc. (Sparks, NV, USA), under the guidance of Metallurgium. The first and second phases comprising bottle roll cyanide leaching tests and column leach tests have been finalized with good acceptable recovery results. The Phase III metallurgical test work continues with column composite bottle roll tests.
