Noricum CEO Greg Kuenzel said, “Both our initial targets, Kvemo Bolnisi and Tsitel Sopeli, have been prioritised due to the strong potential they demonstrate to deliver production in the near term, and this drill programme to delineate a JORC resource is a real step towards evaluating the commerciality of this exciting opportunity further. Noricum’s re-assaying and resource development work has identified this area of shallow, high-grade gold mineralisation and we will now test the continuity between historic diamond drilling and trenching through a drill programme, which will provisionally consist of 19 holes. Considering that high-grade gold bearing secondary quartzites are a feedstock familiar to Noricum’s partner, which potentially positions the Company to capitalise on the excess capacity available at our partner’s operations, it makes sense to firstly focus here.
“The case to develop a mineable resource in this area quickly is made even stronger due to the presence of a 30-year mining licence and the excellent local infrastructure.
“This first phase drill programme will be followed up with grade control drilling early next year and then pit design and mine planning. A similar process will also commence at Tsitel Sopeli early in the new year.”
Noricum Gold Limited, the European focused base and precious metals exploration and development company, has told DirectorsTalk that it has commenced a 19 hole diamond drill programme at Kvemo Bolnisi, one of two priority targets at the 861 km(2) Bolnisi Project (‘Bolnisi’ or the ‘Project’) which is located in the Republic of Georgia.
Highlights
-- Targeting outcropping shallow secondary quartzite high grade gold mineralisation
— The outcropping mineralised area has been identified as having the potential to be fast tracked into production – this campaign is focused on generating an initial JORC resource
— The presence of significant gold mineralisation at Kvemo Bolnisi already identified through previously announced high grade historic trench and diamond drill results including:
o EKBDDH003 – 5.5m @ 5.80g/t Au from 0m
o EKBDDH005 – 4m @ 6.26g/t Au from 0m
o KBTR25 – 12m @ 7.79g/t Au from 0m
o KBTR_010-1 – 12.11m @ 3.46g/t from 0m
— New drilling campaign will test continuity between historic diamond drilling and trenching around EKBDDH003 and EKBDDH005
— This high grade gold mineralisation is not fully closed off to the north east and this will also be an area of focus in the coming months
— Near term production potential is strengthened significantly through the presence of a 30 year mining licence, the current excess capacity at the local partner’s mine processing operation and the excellent existing infrastructure in the area
Kvemo Bolnisi
Kvemo Bolnisi is located less than 7km from the currently operating Madneuli mine and processing plant, owned by the Company’s local partner. Circa 47,000 metres of diamond drilling was completed during the 1970s and 80s to test gold and polymetallic sulphide mineralisation mostly at depth between 30 and 150 metres. A further 13,032 metres of drilling was completed in the last few years principally to test secondary quartzite gold – copper mineralisation at or near surface.

The polymetallic sulphide mineralisation drilled at depth is located on the same NE-SW regional structural trend that hosts both the Madneuli mine and Tsitel Sopeli. More recently, work has focused on the outcropping secondary quartzite gold mineralisation, which has the potential to be developed into a starter pit. Drill holes, existing exploration trenches and some shallow exploratory adits in that area have now been surveyed. Available diamond drill core has been re-sampled as part of a verification process and sample splits sent to an independent overseas laboratory for assay checks.
The Kvemo Bolnisi mineralisation comprises the eastern mineralised block that makes up the bulk of the GKZ approved copper resource; the outcropping gold bearing secondary quartzites also at Kvemo Bolnisi East; the poorly defined Kvemo Bolnisi West polymetallic mineralisation; and a large area between the east and west blocks where little exploration has taken place. The whole of the target area requires more detailed ground IP-resistivity geophysical surveying to broadly define underground targets for follow up.
The outcropping secondary quartzite mineralisation has been successfully tested with both shallow diamond drilling and trenching. Some recent highlights can be seen below. This high grade gold mineralisation is not fully closed off to the north east and this will also be an area of focus in the coming months.
Significant gold mineralisation noted in recent Kvemo Bolnisi diamond drilling:
-- EKBDDH002 - 4m @ 3.51 g/t Au from 0m -- EKBDDH003 - 5.5m @ 5.80g/t Au from 0m -- EKBDDH005 - 4m @ 6.26g/t Au from 0m
More recently, re-assay work identified a new copper discovery in an area previously only assayed for gold. Please see the announcement dated 19 November 2015. The results from this work included:
-- 40m at 2.11% copper ('Cu') from 69m (including 5m at 9.95% Cu) -- 83m at 0.71% Cu from 23m (including 15m at 1.17% Cu) -- 7m at 4.02% Cu from 39m -- 13m at 1.52% Cu from 2m
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
