VANCOUVER, March 2, 2021 - Awalé Resources Ltd. ("Awalé" or the "Company") (TSXV: ARIC) is pleased to announce the results of preliminary metallurgical testwork undertaken on 781 mineralized drill core samples from the Empire discovery, with exceptionally high (average 95.4%) gold recoveries being reported from LeachWELLTM bottle roll tests.
Highlights
- Exceptionally high gold recoveries (average 95.4%) were returned from LeachWELLTM analyses of all drill core samples at the Empire discovery with gold grades > 0.2 grams per tonne Au ("g/t Au"). Approximately 94% of the samples analyzed represented fresh (unoxidized) samples, with the remainder being oxide and transitional material.
Table 1: Summary of LeachWELLTM recoveries for all mineralization types at Empire Main
Mineralization | Lithology | Number of | Average Percent Recovery - |
Oxide | Diorite | 35 | 97.6% |
Transitional | Diorite | 12 | 98.7% |
Fresh | Diorite | 734 | 95.2% |
Total | 781 | 95.4% |
After initial test work using fire assay, screen fire assay and leach testwork was undertaken on the discovery holes, the LeachWELLTM method has been utilized for routine analysis of all gold mineralized samples at Empire Main. LeachWELLTM is an accelerated leach method and provides an indication of potential recoveries in industry-standard gold recovery circuits. Percent recoveries are calculated from fire assay tests on the leach residues (see Quality Control Section).
Company CEO Glen Parsons commented today:
"Achieving high average gold recoveries of 95.4% from LeachWELL bottle rolls is an outstanding result for Awalé. A bonus is the extremely high recoveries in fresh rock samples as shallow depths of oxidation mean the greater portion of the mineralization at Empire is fresh and un-weathered material.
This early-stage metallurgical test work indicates Empire is amenable to conventional or traditional gold processing and gold extraction.
Additional to these excellent metallurgy results the company eagerly awaits analysis results from the final 5 (OEDD-33 to OEDD-37) diamond holes of the recently completed drill program at Empire, these holes were drilled to test steeper plunges to mineralization down to a depth of 120 vertical meters.
Proximal to these, results are also expected for 'brownfield' auger targets at Empire West, Empire Gap and Charger. These targets form part of the pipeline to more discoveries and more gold ounces to complement the Empire Main zone, along the Empire Corridor."
Follow - Up Exploration Plan at Odienné
Awale remains confident of the upside potential of the Empire Corridor and has an aggressive exploration campaign designed for 2021. The near-term focus for the Odienné project is as follows:
- Testing steep plunge model for Empire Main - 897.3 meters of diamond drilling have been completed assays currently pending (figures 1and 2). Results will guide the next phase of step-out diamond drilling on the known high-grade gold mineralization at Empire Main.
- Testing potential eastern offsets from Empire Main in addition to western extension targets. A 500m gap exists between current drilling at Empire Main and Anomaly 1 and the western extension of the Empire structure. A program of 240 Auger holes for 964m was completed on the 8th of December as a targeting exercise and will guide the next phase of drilling at Empire Main.
- Proximal to this, a new parallel structural target (the "Charger Target") to Empire has been Auger drilled c. 3 km to the NNE of Empire Main. This will feed into the next program scout drilling over the greater empire structure. Results are also pending for this auger program.
-
- The Charger prospect is approximately 3km north of Empire. Legacy soil sampling by Randgold returned up to 1677ppb Au within an 600m long greater than 100ppb Au anomaly. Initial mapping has revealed diorite body central to the prospect area that is bound by a package of basalts and intermediate volcaniclastics and tuffaceous rock.
- Further detailed interpretation and understanding of the first pass intercepts from scout drilling at Anomalies 1 and 2, as well as anticipated further results from Anomaly 1 - follow up drilling.
About the Empire Main Discovery
Empire Main discovery is a high-grade gold discovery characterized by multiphase deformation, alteration and veining hosted within a diorite intrusion. Mineralization is associated with early potassic (biotite) alteration+/- Au and pyrite, calc silicate alteration (rare garnet, clinopyroxene and pyrrhotite), and later carbonate and silica sericite alteration. The abundant free gold is likely late and associated with the final silica-carbonate-sericite phase.
High-grade mineralization is hosted in brittle/ductile quartz vein arrays that are oriented from east-west to northeast and exhibit both shallow and steep plunges. The host diorite lies within a > 20 kilometer long and 1 to 2 kilometer wide brittle/ductile shear zone, named the 'Empire Corridor'. Mineralization at the Empire Main discovery remains open along strike and down dip/plunge. Beyond the Empire Main discovery there is high potential for discovery or similar or larger deposits along this fertile structural corridor.
Empire was discovered through systematic exploration by Awalé, resulting in a coincident geology, gold/arsenic geochemistry, and ground geophysics (Induced Polarization, or "IP") anomaly. This discovery demonstrates high grade gold bearing fluid flow within the empire corridor, and the company plans to continue exploring along this fertile shear zone to make new discoveries and rapidly accrete the gold inventory through extensions of know mineralization and new discoveries.

Quality Control and Assurance
Analytical work for drill core and RC percussion samples is being carried out at the independent Intertek Laboratories Ghana Ltd. an ISO 17025 Certified Laboratory. Samples are stored at the company's field camps and put into sealed bags; they are stored securely until collected by Intertek for transportation to Ghana.
Drill holes reported in this release are HQ core and have been sampled as ¾ core (approximately 6 kg/ meter) with ¼ 'sliver' of the core sample being reserved as a library sample at the company offices. The remaining ¾ core samples are logged in the Intertek tracking system, weighed, dried and finely crushed to better than 70%, passing a 2 mm screen of which 50% is pulverized to 85%, passing a 75-micron, the remaining 50% is reserved. The pulverized sample is then leached by the LeachWELL method with a further 2 Fire Assays are completed on the tail samples from the leach to monitor leach efficacy. Total gold is reported from leach and fire assays, at grades of >0.2 g/t gold the leach is recovering 95.4% of all gold.
Blanks, core duplicates, crush duplicates and certified reference material (standards) are being used to monitor laboratory performance during the analysis. Due to the presence of free gold the lab was requested to run a quartz wash between each sample during preparation, a selection of the quartz wash samples is also routinely analyzed.
