Noricum Gold LON:NMG CEO Greg Kuenzel said, “The resources at our Project in Georgia are extensive as is the historic data available so I am pleased to report that the receipt of our first batch of verification samples from historic drilling undertaken at Tsitel Sopeli increases the already high level of confidence placed on the precision and accuracy of this historic data. A second batch of samples from Kvemo Bolnisi is currently being prepared and will be submitted for assay shortly, providing us with further confidence and news flow going forward.
“Resource verification and expansion is a critical workstream towards developing our starter pits at both the Tsitel Sopeli and Kvemo Bolnisi deposits towards production to deliver cash flow. A trenching programme will commence shortly at Tsitel Sopeli, focusing on the at surface gold and copper mineralisation and we will also be commencing a detailed geophysics survey at the same target, targeting existing anomalies with a more detailed IP and magnetics survey including extensions north-east and south-east of near surface mineralisation. Similar work is ongoing at Kvemo Bolnisi. This is an exciting time in our development and we are pleased to be working with experts who share in our belief that Bolnisi presents both near and long term mining opportunities due to its size and proximity to infrastructure.”
Noricum Gold Limited, the European focused base and precious metals resource development company, tells DirectorsTalk that resource conversion and development work currently underway at Tsitel Sopeli and Kvemo Bolnisi, two primary targets at the Company’s 861 km2Gold & Copper project in the Republic of Georgia, is progressing positively.
This update follows a detailed site visit by resource consultant Mark Owen who has begun to validate the resource verification work conducted to date and defined ongoing activities to convert the existing non-JORC Soviet Resources to JORC standards. The site visit included a tour of the Madneuli processing plant and heap leach operation where toll treatment offers a potential fast track to production. The Project has combined, drill defined, non-JORC C1, C2 & P1 Soviet Resources of 980,000 tonnes of contained copper; 6.6 million ounces of gold; and 22 million ounces of silver.
Highlights
· Focus of work remains on fast tracking low cost production at both Tsitel Sopeli and Kvemo Bolnisi due to near surface mineralisation at these targets
· High degree of confidence in the precision and accuracy of historic assay data – results from initial resource verification work on historic diamond drill core and reverse circulation (‘RC’) pulps show a high level of correlation
· New batch of duplicates and splits currently being prepared for submission and analysis to strengthen this confidence further
· Geophysics consultants, Southern Geoscience, recently on site and preparing for new Induced Polarisation, (“IP”) geophysics programme
· New trenching campaign focussing on surface mineralisation commencing shortly at Tsitel Sopeli as a pre-cursor to RC drilling programme
· Work being undertaken at Tsitel Sopeli continues to focus on open pit targets
Resource Verification
As part of the resource verification work being undertaken to convert the Soviet resource to JORC, historic diamond drill core and RC pulps will be resampled and assayed. A high level of correlation between the historic assays and the new assays will allow the Company and its resource consultant to place a high level of reliance on these historic results and as a result, this will greatly speed up the process of verification and conversion.
A first batch of 105 samples including resampled core and pulps from Tsitel Sopeli, certified standard material and blank standard material was recently submitted to ALS Minerals in Ireland as a check to historical drilling and sampling results completed by Noricum’s local partner Caucasian Mining Group (‘CMG’). The results received from ALS only show very minor variation as is common with gold and as such verify the historical results achieved by CMG in its comprehensive exploration efforts. This is a significant milestone in the Company’s resource development activities.
A second batch of samples from Kvemo Bolnisi are currently being prepared for re-assay and verification.
Mark Owen, the Company’s Resource Consultant, recently completed a site visit which included a broad overview of the geology of the Bolnisi region and more specifically on areas comprising near surface resources at Tsitel Sopeli and Kvemo Bolnisi. Mr. Owen also spent significant time with both the Company’s on site personnel as well as CMG personnel reviewing sampling procedures and visiting CMG’s on site laboratory facilities as well as the Madneuli copper & gold mine and processing plant facilities. A detailed review was undertaken of the Company’s sample preparation methodology to ensure compliance with standards required for the resource verification.

Geophysics Programme
Bill Peters from Southern Geoscience, the Company’s geophysics consultants, recently undertook a site visit focused on the commencement of a new magnetic and IP programme at both Tsitel Sopeli and Kvemo Bolnisi as well as an overall review of historic geophysical work over the entire Licence area. This programme will build on the work recently completed by our local partner, which has highlighted significant new IP anomalies at both sites.
Further east of the near surface mineralisation at Tsitel Sopeli there are a number of geophysical targets with coincident geochemical anomalies that warrant detailed investigation. One of these targets to the north east represents the possible up-dip expression of the deeper and significantly large Tsitel Sopeli resource that has been drilled extensively. There is further evidence to suggest that mineralisation at Tsotel Sopeli may plunge south-east of the currently delineated mineralisation in an area where little exploration has taken place. These eastern and south-eastern extensions will be the primary focus of the IP survey being planned.
A final target at Tsitel Sopeli is that of the black ore defined in TSDDH004 and 002. This mineralisation is likely to represent a near sea floor epithermal vein rich in gold as shown by the recent assay validation work. This black ore had a significant magnetic susceptibility in one of the drill holes and this could allow it to be defined by geophysics.
A similar new geophysical survey is also being planned for the Kvemo Bolnisi Project and a decision will be taken on the extent and scope of this survey once recommendations have been received from Southern Geoscience.

Resource/Reserve Classification
The former Soviet system for classification of reserves and resources was developed in the 1960’s and is still used today in Russia. It divides mineral concentrations into 7 categories:
1. Fully explored reserves or resources – A, B and C1
2. Evaluated reserves or resources – C2
3. Prognostic resources – P1, P2 and P3
In a similar fashion to the more commonly used international standards (JORC or 43-101), the Soviet system assigns reserves and resources to classes based on the degree of reliability based on the various stages of exploration. A, B, C1, C2 and P1 reserves and resources can be matched to the JORC and 43-101 categories.
A broad equivalence between the classifications may be presented as:
Russian |
International Reporting Code, JORC, 43-101 etc |
A,B |
Proved reserve / Measured resource |
C1 |
Proved or Probable reserve / Indicated resource |
C2 |
Probable reserve / Indicated Resource / Inferred Resource |
P1 |
Inferred Resource |
