Increased Exploration Target at Baita Plai
Vast Resources plc, the AIM-listed producer & development company, is pleased announce an increase to the exploration target for its Baita Plai Polymetallic Mine (‘Baita Plai’) in Romania. Further to the recent Baita Plai JORC Resource and Reserve report (see RNS dated 29 October 2020) (the ‘Report’), which confirmed a JORC compliant mineral total gross resource of 608,000 tonnes at 2.58% copper (‘Cu’) equivalent and an exploration target in the range of 1.8M-3M tonnes, Vast has now had the opportunity to review further historical data which has only recently been made available and is pleased to update the market that the Antonio North skarn, which is one of a number of high priority exploration targets, may be more extensive than previously interpreted.
The previous 1.8M-3M tonnes exploration target referred to in the Report assigned 0.2M–0.5M tonnes to the Antonio North skarn and also included the historical 1,800,000 tonnes under the NAEN Russian Code, as announced on 10 December 2014. Following an analysis of historical data records, the exploration target tonnes assigned to the Antonio North skarn has been updated to between 1.4M–2.8M tonnes giving an increased total gross exploration target of between 3.2M–5.8M tonnes.
Based on these findings, the Directors believe that the Antonio North skarn represents a major near to medium term mining opportunity illustrated below in Figure 1. An underground exploration drilling programme is currently being compiled to better determine its potential.
Andrew Prelea, CEO of Vast Resources PLC commented: “Antonio North represents a major opportunity for the Company not only to expand our production profile but also to significantly extend the life of mine plan at Baita Plai. In our initial exploration target of between 1.8M–3M tonnes, Antonio North represented 0.2M-0.5M tonnes; however, based on this new information Baita Plai and subject to further confirmation we will have an increased exploration target of between 3.2M–5.8M tonnes. The significant value potential of Baita Plai continues to reveal itself and we are committed to maximising this.”
Further InformationData comprising available historical assay results, logged lithologies and general plan data was recently collated from data archives accessed by the mine geologists and Mr. Harvey, which has enabled the construction of a basic geological model for the Antonio North skarn. This has led to a revised Company determined exploration target for Baita Plai as detailed below:
| Exploration Target | Range (M tonnes) | Range (Cu %) | Range (Pb %) | Range (Zn %) | Range (Ag g/t) | Range (Au g/t) | ||||||
| Min | Max | Min | Max | Min | Max | Min | Max | Min | Max | Min | Max | |
| 3.2 | 5.8 | 0.50 | 2.00 | 0.10 | 2.00 | 0.10 | 2.00 | 40.00 | 80.00 | 0.20 | 0.80 | |
The Antonio North skarn is located approximately 200m to the north of the Antonio skarn. Historic drilling from 15 level and 16 level identified a skarn below the Antonio skarn, which was subsequently mined between 15 and 16 level. Underground development on 17 and 18 levels is limited and intersected the Antonio North skarn on the western margin of the skarn. Limited mining of the Antonio North skarn has taken place on 17 and 18 levels due to the underground development not continuing below 16 level as depicted in Figure 1 (to view the release with the illustrative diagrams please see the link at the bottom of the announcement).

There is a major near to medium term opportunity for the mine to extend both the 17 and 18 level development along strike of the Antonio North skarn and to commence mining as the infrastructure is developed.
Analysis of the historical drill hole records which are presumed to have been drilled in the early 1990’s, revealed numerous skarn intersections. Unfortunately, not all the records had corresponding assay data or other data such as date drilled, type of drill used or where laboratory assays were undertaken. The Antonio North skarn has been interpreted from underground intersections in 17 and 18 level development on the western margin, from underground intersections in the 15 and 16 level development above, and from four historic underground drill holes drilled from 15 level.
The drill holes intersecting the Antonio North skarn are L-16, L-28, 1388BSK and 1389BSK. The assay values from these drill holes are provided in mm. A weighted average copper % is calculated as 1.66%, lead % at 0.02% and zinc % at 0.08%. The drillholes and extent of the newly interpreted Antonio North skarn are depicted in Figure 2.

Based on the recent drilling in the adjacent Antonio skarn, the Company expects that a similar grade range for copper, lead, zinc, gold, and silver would be present in the Antonio North skarn. The historic drillhole intersections show that the grades are present and within the same broad range.
An underground drilling programme is being developed to test the geological interpretation by drilling a series of underground diamond drill holes from 15 level to intersect the Antonio North skarn.
