HIGH GRADE GOLD VALUES CONFIRMED IN PENTLAND PROJECT
• Over minimum 500m strike length from surface sampling
• Drilling due to commence in October
Key Points
-
Total of 36 collected samples average 7.2 g/t gold.
-
Follow-up sampling has confirmed the presence of high-grade polymetallic mineralization in the historic Toomba workings.
-
� A newly completed IP geophysical survey has identified coincident anomalies which will be developed into drill targets.
-
� Intention to drill the Toomba Prospect during October.
China Yunnan Copper Australia Limited (ASX:CYU) today announced that followup sampling over the Toomba Prospect has confirmed the presence of high grade gold and significant base metal grades reported previously. A geophysical survey has generated coincident anomalies that indicate the potential for mineralisation to be found at depth.
The Toomba Prospect of the Pentland Project was identified from reconnaissance mapping, sampling and data collation of previously collected samples. The sampling and mapping program is continuing and drill targets are being generated in preparation for drilling planned for October.
1
– Pentland Project EPM 11487, EPM 12900, EPM 12901
Mapping and sampling of the historic Toomba workings (Refer Figure 2) has confirmed the greater than one ounce gold values and strong base metal anomalies in spoil reported historically. Peak values include 44g/t gold, 128 g/t silver, 6570 ppm copper, 3.41% lead and 4.8% zinc.
Sampling of the previously unrecognised Central Zone has confirmed the potential for further poorly exposed or blind targets within the prospect.

Table 2: Results from sampling over the Central Zone.
This poorly exposed and previously unworked structure shows significant evidence of mineralisation. Highest gold values are in sulphidic vein material.
A geophysical (IP) survey over the prospect has not only identified multiple linear anomalies coincident with the known structures, but also well defined, broad anomalies at depth in the SW and near surface in the east of the grid that reinforces the potential for larger, bulk volume targets at depth
The Toomba Prospect comprises four parallel NNE vein structures and zones of veinlets up to 400m long within an area 1km by 750m. These mostly occur within an outlier of the Amarra Granite within the Grasstree Leucogranite. The southern edge of the prospect is overlain by the Tertiary Campaspe sediments.
Recent sampling over the Toomba Prospect (Tables 1 & 2 above) in the east of EPM 12900 has been successful in replicating the strongly anomalous gold and base metal values reported by previous companies. Sampling was carried out on veins in outcrop and on material found in the mullock heaps around the historic mine workings.
The recent IP geophysical survey generated three distinct classes of anomalies over Toomba. A group of NW trending planar anomalies appear to correspond to the regional tectonic fabric, as seen clearly in aeromagnetic surveys. Weaker, high-angle, planar anomalies are coincident with the known vein structures, especially the Old Toomba Workings. A group of broad anomalies occur at 150 to 200m depth in the SW and nearer surface in the east. These may represent

larger, disseminated or breccia-hosted mineralisation at depth.
The Toomba Prospect comprises a series of four NNE trending vein structures over an area of 1km by 750m. Three groups of old workings are reported in the area: Toomba, Toomba East and Lady Barrington. The main mineralisation takes the form of coarse-grained banded quartz – sulphide veins with abundant iron oxides hosted within a sericite altered granite.
CYU has identified multiple shallow pits and shafts along a 500m strike length on the eastern side of Toomba (Figure 2 below). Previous records show that sampling in this area has returned gold values of up to 37.5g/t with 5,267ppm lead, 22,800ppm zinc and 1,483ppm copper.
Planned Exploration
Toomba
A drill rig has been contracted to start drilling in Toomba in mid October. Currently a 2000m program of reverse circulation holes is planned to test both the known high grade gold structures from surface and the geophysical anomalies to a depth of approximately 200m. In addition, results are pending from a close-spaced soil-sampling program testing for blind, near-surface mineralised structures.
