KARABALTA

The Karabalta site was identified based on the data of predecessors, where schlich and lithochemical anomalies of gold were found on the left bank of the Karabalta River.

Subsequently, during office processing using the Vertical Mapper method in the MapInfo a prospecting area was identified, which required an additional exploration.

The geological structure of the investigated work area is mainly represented by terrigenous rocks of the Karabalta Formation (O3kb).

To verify the lithochemical anomalies of the predecessors, a small amount of work in this area was concentrated on the left bank of the Karabalta River. Here, loose sediments were sampled using the Stream Sediment method. These samples were taken on dry valleys from the surface from the undersoil-vegetation layer to a depth of 0.4-0.7 m. The weight of the samples was 10-12 kg.

Samples were wet sieved to <80 mesh at the Alex Stewart Laboratory in Karabalta and then analyzed. In total, 23 samples were taken.

In one sample, a gold grade of 0.134 g/t was noted, in another five samples the gold grade varied from 0.011 to 0.024 g/t (which is a good indicator for this type of sampling), the rest of the samples had the grades of less than 0.01 g/t.

The prospects of the Karabalta remains unclear on its potential due to the small amount of work carried out.

AKSU

A small amount of prospecting work was carried out on the Aksu site. The routes were conducted in areas of known occurrences and points of mineralization. A total of 9.56 linear kilometers of search routes was done, 41 chip samples were taken, 24 samples were taken using the Stream Sediment method.

A sampling of one of the quartz veins among the wax-red siltstones of the Lower Chonkainda Subformation and another one 3 m later showed: the width of the first vein is 0.4 m, and the second – 0.3m. Their length varies from 15 m to 20 m. White quartz contains disseminated sulfides and malachite along the cracks. The gold grade in the first vein was 0.003 g/t and in the second – 0.144 g/t. The copper grade in the first case was 0.047% and in the second – 1.5%.

Three delineating samples were taken from the host siltstones visually un-altered. However, the first sample returned the gold grade 0.003 g/t, and copper – 0.11%; in the second sample gold – 0.23 g/t, and copper – 0.92%; and in the third gold – 0.019 g/t, copper – 0.092%.

In the sample taken from talus represented by greenish siltstones of the Lower Chonkainda Formation gold grade was 0.012 g/t, and copper – 0.65%.

Mineralization was spread all over the place was obviously associated with quartz veins and veinlets forming stockwork structure.

In addition, loose sediments were sampled using the Stream Sediment method. A total of 24 samples were taken. Three samples returned with relatively high gold grades – 0.015 g/t, 0.012 g/t, and 0.011 g/t. The rest of the samples showed gold grades ​​in the range of 0.003-0.005 g/t and the presence of bismuth, molybdenum, and tungsten.

The prospects of the Karabalta remains unclear on its potential due to the small amount of work carried out.

PROMEJUTOCHNOE

Promejutochnoe prospect was highlighted in the analysis of spectrozonal satellite images. A very strong and contrast iron anomaly was identified on it, which most likely reflects rather strong sulfide mineralization (pyrite).
