HIGH-GRADE ZONES IDENTIFIED AT TAVSAN

 

Ariana Resources plc ("Ariana" or "the Company"), the AIM-listed exploration and development company operating in Europe, is pleased to announce the completion of its resource sampling programme for the Tavsan Gold Project ("Tavsan" or "the Project") in Turkey.  Tavsan is part of the Red Rabbit Joint Venture with Proccea Construction Co. and is 50% owned by Ariana through its shareholding in Zenit Madencilik San. ve Tic. A.S. ("Zenit")*.

 

Highlights:

 

·    156 surface rock-saw channel lines were completed across Tavsan, significant results including#:

 

18.2m @ 5.03g/t Au + 2.1g/t Ag

9.9m @ 6.08 g/t Au + 2.4g/t Ag

31.3m @ 1.85g/t Au + 0.9g/t Ag

 

·    Significant results supporting a potential conversion of the JORC Exploration Target at Tavsan South to Inferred Resources, include:

 

3.5m @ 9.28g/t Au + 30.5g/t Ag

4.5m @ 4.30g/t Au + 5.3g/t Ag

5.0m @ 1.72g/t Au + 5.3g/t Ag

 

·    Over 60 outcrop locations sampled which will be incorporated in to the next resource estimation for Tavsan, scheduled for completion during Q2 2020. 

 

·    Follow-up infill resource drilling programme planned for the next phase of project development.

 

Dr. Kerim Sener, Managing Director, commented: 

 

"These results reflect extremely positively on the resource-focused work we have been undertaking at Tavsan. They demonstrate that the sampled areas of outcropping mineralised jasperoid are typically higher grade than the overall resource. Some of these results are exceptional, such as 18.2m @ 5.03 g/t Au, suggesting that there is an opportunity to identify several rich zones of structurally-controlled mineralisation within the orebody as a whole, and that these higher-grade areas are likely to be encountered from surface to a depth of 10-20m below surface. We will be working on a revised mineral resource estimate for Tavsan during Q2 2020 which will form part of our mine plan for the Project, once final permits are received."   

 

* All figures relating to Mineral Resources, including the financial model, are quoted gross with respect to the Joint Venture; Ariana holds 50% of the project through its JV company.

 

# Results of channels are quoted based on a zero grade being applied to some short interval gaps of up to 1.7m where samples could not be collected due to lack of in-situ outcrop.  There are only 5 cases of this occurring in the intercepts recorded.

Rock-saw programme

 

During Q4 2019, the Ariana exploration team, working in association with the Zenit JV, collected samples along 156 rock-saw channels, totalling a combined length of 1,158 meters from key outcrops across the Tavsan Project (Figure 1). Outcrops were selected on the basis of detailed outcrop mapping of silicified jasperoid, known historic workings, epithermal quartz veins and existing drilling results. Samples were extracted on the basis that each outcrop was sampled at least twice, and in multiple directions, typically along the long and short axis directions relative to the orientation of the outcrop.

 

Mineralisation at Tavsan largely occurs on two dominant structural trends, with the majority of mineralisation located along the gently dipping and undulating plane of a NE-SW trending thrust-fault. The second, subsidiary trend for mineralisation is controlled dominantly by a unit of neritic limestone and a series of NW-SE linkage faults, trending at about 90 degrees to the primary fault plane.

Figure 1: Map of the Tavsan project area showing the location of outcropping mineralised jasperoid (in red) and currently designed open-pits (yellow outlines).  Many of the exploration targets lie along NW- and NE-trending axes associated with a thrust-fault and its subsidiary structures.  Significant results from the rock-saw channel programme are shown in addition to key drilling intercepts in the area identified in the South Zone.

 

The purpose of the programme was to provide a further increase in the confidence of the resource classification, and to reduce planned infill drilling meters for future resource development work.  The sampling included areas that are currently classified as part of the JORC Exploration Target and Inferred Resource, with a view to improving confidence in the resource estimate and an improvement in the resource classification.  A total of 751 samples (including 118 QA/QC samples), averaging a length of 1.8 meters were extracted during the sampling activities (Table 1). Of these samples, 676 were sent to the Kiziltepe mine laboratory for gold and silver fire assay only. A further 76 samples were sent to ALS in Izmir for gold and silver fire assay and multi-element ICP analysis.

 

Significant results (intercepts exceeding 1g/t Au) have returned from 72 of the 156 channels, with best results including:

 

TAV-CH010-19: 18.2m @ 5.03g/t Au + 2.1g/t Ag

TAV-CH032-19: 9.9m @ 6.08 g/t Au + 2.4g/t Ag  

TAV-CH016-19: 31.3m @ 1.85g/t Au + 0.9g/t Ag

 

Some of the highest-grade results returned include:

 

TAV-CH087-19: 3.4m @ 14.24g/t Au + 1.2g/t Ag

TAV-CH072-19: 5.0m @ 9.59g/t Au + 3.5g/t Ag

TAV-CH058-19: 3.5m @ 9.28g/t Au + 30.5g/t Ag

 

At Tavsan South, a JORC Exploration Target area which contains 63 historic workings and which occurs in association with significant historic drilling intercepts (e.g., OR3: 9m @ 1.3g/t Au + 4.3g/t Ag and ODX53: 6m @ 3.37g/t Au + 3.7g/t Ag), returned results including:

 

TAV-CH058-19: 3.5m @ 9.28g/t Au + 30.5g/t Ag

TAV-CH057-19: 4.5m @ 4.30g/t Au + 5.3g/t Ag

TAV-CH051-19: 5m @ 1.72g/t Au + 5.3g/t Ag

 

The channel sampling results obtained from this programme, in addition to supporting historic data, provides for the definition of an Inferred resource at Tavsan South.

 

The Tavsan channel sampling programme has aided the definition of grade across the mapped jasperoid outcrops within the immediate area of the planned open-pits, in addition to refining the future resource potential of Tavsan. The pending drill plan is now being revised to incorporate the new surface data to reduce the number of meters required for the next phase of drilling.

Sampling and Assaying Procedures

 

The Tavsan rock-saw sampling programme was conducted using the same sampling procedures used within Ariana's drilling programmes. Jasperoid outcrops were historically mapped at 1:1,000 scale. More recently (April 2019), selected outcrops were individually assed for safe and effective sample extraction. Channels were typically marked-up into 1m segments. A dual bladed, petrol powered rock-saw was then used to cut two equally spaced grooves along the long and short axis of each outcrop. Spacing between the two diamond blades on the rock-saw was 25mm to replicate half HQ diamond drill core. Individual samples were typically extracted as 1-2m composites, with average composite lengths for the entire programme equalling 1.8m. All samples were organised into batches in line with Ariana's quality control procedures. A total of 676 samples were submitted (including 118 QA/QC samples), to the Kiziltepe Mine Laboratory for fire assay gold-silver analysis. A further 76 samples were sent to the ALS Laboratory in Izmir for fire assay and multi-element ICP analysis. 

 

All samples were assayed at the mine laboratory using a 30g fire assay. Samples were analysed in line with normal operating procedures for grade control analysis conducted for the Kiziltepe open pit. The addition of blanks, standards and duplicates were routinely included into the sample batches as part of Ariana's sampling procedures in adherence to the 2012 JORC Code. Duplicate samples were extracted by cutting an additional channel line within 5cm from the original samples. Quality control checks have determined that blanks and standards passed and duplicate samples showed good correlations. Laboratory sample preparation, assaying procedures and chain of custody are appropriately controlled. The Company maintains an archive of photographic records for all channel locations for future reference.
