Results have been received for 53 rock chip samples and one standard submitted following start-up of fieldwork in
Sixteen samples were taken in the west of the Lead Trial area, the majority uphill from the main historic working associated with breaks in slope over an area of 200m by 170m. The samples consisted of well-developed quartz-vein stockworks in silicified felsite and quartz-rich boulders including hydrothermal breccias. Some of the breccias contained silicified clasts of felsite and schist along with sporadic blebs of galena and sphalerite. Separate crosscutting banded quartz, bands of saccharoidal quartz and later barite were observed in some boulders. Highlights include:
· Sample with 3.05g/t Au, 1.14% Pb and 0.46% Zn from quartz breccia with mica clasts,
· 2.27g/t Au in a boulder of quartz with small felsite clasts (7.83 g/t Au in aqua regia leach), and
· 1.71g/t Au in a quartz-stockwork breccia boulder.
Two other samples had 1.06g/t Au and 0.96g/t Au respectively while many have anomalous gold. This area is over 2km from the Lead Trial-Dunan area to the southeast but multiple float boulders and exposure of outcrops has allowed geologists to develop a better understanding of the mineralising system. Mineralisation appears to be focussed at the brecciated contacts of the felsite sill although a mineralised extensional joint set with northeast trend has also been observed and may also be important as a secondary control on the mineralisation. An additional 12 samples have been taken extending the boulder train 200m to the southeast. Result are pending.
At the Lead Trial-Dunan area 14 float samples were taken. The best sample from a boulder measuring up to 90cm across returned 2.12g/t Au, 22.3g/t Ag, 4.31% Pb and 1.1% Zn. This sample was taken 140m downhill from the large boulder or subcrop that gave 17.15g/t Au. A sample from a quartz-barite cobble taken 97m to the west of the former sample returned 0.73g/t Au, 0.52% Pb and 1.98% Zn. The results give further confidence that there is a proximal source to mineralisation in this area, however, exposure is poor. In order to better define the target, a soil sampling survey has commenced with sample spacing of 100 x 50m centred on the high-grade boulder area.
A large representative chip sample weighing 8.49kg taken from dumps at the historic working at Lead Trial was analysed for coarse gold by the metallic screen method (Au-SCR24C) at the ALS laboratory in Loughrea,
This confirmation of the presence of coarse gold means that the soil sampling analysis has been chosen specifically to analyse for gold with multi-element using a larger 25g sample, which should give a more representative gold analysis. The analysis used will be the AuMe-ST43 package at ALS in Loughrea,
A waste dump of white quartz vein material located 1.6km west north west and downhill of the historic Corrie Buidhe silver mine was sampled by the Company for the first time and yielded low to medium-grade gold. A selective sample containing arsenopyrite in quartz returned 6.98g/t Au, 10.55g/t Ag and 862ppm As, a sample with galena in quartz had 0.44g/t Au, 47.9g/t Ag, 1.18% Pb and 0.25% Cu and a representative chip sample from the dump returned 0.88g/t Au, 61.7 g/t Ag, 0.16% Cu, 0.25% Pb and 10.35ppm Te. The results are significant as this occurrence is 225m below the Corrie Buidhe mine workings and suggests that the historic mine, where up to 18 high-grade silver-bearing quartz veins were worked, may grade into more auriferous mineralisation with depth or along strike. To date, a total of 14 samples taken by both Erris Resources and GreenOre Gold from quartz veins and quartz mine dumps at Corrie Buidhe have returned an average of 149g/t (4.77 oz/t) Ag, 308pm Bi and 1.6% Pb with anomalous Te. The distinctive high Ag-Bi-Pb-Te signature over a large area with 1.7km extent warrants further investigation especially given the high silver grades and new gold result to the west and downhill. Silver grades up to 424g/t have been sampled by GreenOre at Corrie Buidhe while an in-situ vein sample in the mine portal yielded 300 g/t Ag. The dump material is believed to have been hand sorted so that galena-bearing higher-grade material has been removed during operations in the 18th Century. Veins are reported to be from 20cm to up to 1m wide. The Company will continue to investigate how this prospect is related to the historic Tomnadashen copper mine located a further 250m downhill and 3.1km to the north of the new samples. At Tomnadashen, mineralisation is structurally controlled, and sulphide-rich samples have yielded high Cu, Ag, Mo and Bi along with some anomalous gold up to a maximum of 1.58g/t Au and 200g/t Ag. The Tomnadashen-Corrie Buidhe mineralisation may be part of a single gold-silver-lead-zinc-copper system. The Company will review and consider its findings in relation to this prospect.
Mapping and sampling will continue at Lead Trial in parallel with the soil survey which is now underway. The results will be reviewed as received and the work plan amended as required in order to expand or close off anomalies and mineralised boulder trains and rapidly identify drill targets. The Company plans to trial a ground magnetic survey across the Lead Trial prospect to determine if the contacts of the felsite sills and structures can be mapped. If the results are positive, then the survey can be expanded to cover the entire +3km trend. The combination of geophysics, detailed mapping and soil and rock geochemistry will be used to identify future drill targets at Lead Trial. Other targets within the large licence area such as the Corrie Buidhe area will be investigated to determine if they have economic potential. The field team have secured a base in the area for fieldwork and the Company looks forward to advancing these prospective targets.
