序言
2006年，Kaskad N的勘探集中在Skalistoe,以及Aleksandrovskoye地区，特别是Veseloe 勘探前景。之所以决定集中在这些地方，主要是基于人们所认知的地理优势，现有的数据资料和允许进入的公路分布等因素综合考虑的。此外，在2007年中，其他八个地区的勘探计划也随之确定下来。
依据历史数据资料，Kaskad N 推断220平方千米的Kuludjun获许可地区仅仅开发了大约25％。
6.2 Veseloe 勘探前景
Veseloe勘探地区位于获许可地域的东南部，与Bapern-Veseloe Fault地区（图5）相接壤。在苏联时期（图23和24）获许可的地区曾大规模的钻孔和挖沟，显示有3.1公吨黄金的C1+C2资源和其他1.9公吨黄金未定义的C1+C2+P2资源。Kaskad N于2006年完成了第一阶段填空钻井项目，大多数的化验结果尚未出来。
矿化出现是连续的，高等级晶体（>2 g/t Au）的趋势从北到南延伸，宽度从3米至5米，长度从50米至150米（图23）渐变。宽度长达10米的高等级晶体并不常见。矿化作用倾向于东方，大约50度角，虽然高等级晶体可能卷拢角度变得更陡（ca. 60°）和更浅（ca. 60°）（图24）。横截面高等级晶体有一定程度的下倾，在50至200米之间，形成亚平行主体。几个亚平行高等级晶体不会在地表上显露出来，而是被更深的钻孔在地表50米以下（见图24）被截断。
根据0.1 g/t Au的等高线（见图23和24）划分，高等级晶体但低等级矿化出现在地表附近。 表面宽度在10至75米之间并形成一个从北西北至南东南的宽阔地带，大约400米长。低等级的区域又形成小的分支并很可能与主要Bapern-Veseloe Fault的分支相结合。在横截面中，低等级矿化倾向东面，角度约为45°，其厚度在30至50米之间（见图24）。
未经证实的苏联钻孔处获得的化验结果表明Veseloe勘探前景的核心部分矿化情况明显。从地表深度150米处开始截断较好，按照截面8的线路进行（见图24），包括：26.4米11.6 g/t Au, 14.9 米5.68 g/t Au, 11.4 米7.03 g/t Au, 6.0 米 1.95 g/t Au 及8.1 米5.4 g/t Au。
现有的横截面表明Veseloe露天矿场的Veseloe矿石主体正在向北，向南逐渐变薄（图24和图25及26），且厚度/等级截断相对较小。可是这也折射出苏联钻探的更大潜力空间（每个截面中的钻孔见的距离为ca.50至200米）。
2006年，Kaskad N 钻探项目将目标设定为近地表，使用一连串的近距离垂直和有角度的钻孔完成钻探。大多数的化验结果尚未出来。Kaskad N在氧化矿化物中进行的黄金化验结果是Veseloe露天矿场（见图27）的基础。中途截取包括3.0米2.54 g/t Au, 2.2 米 4.95 g/t Au, 5.9米2.12 g/t Au, 6.0米3.3 g/t Au, 5.8米2.65 g/t Au 以及8.5米1.95 g/t Au.

6.3 Vladimirskoe-Preavednoe 地区
Vladimirskoe-Preavednoe地区位于Veseloe 地区（见图6）的北西北部约2公里处。苏联时期拥有挖沟，开采和钻井的执照（见图28和29）。该区域拥有2.3公吨黄金的C1-C2 近地表资源，及1.6公吨黄金的P1资源，平均等级在3.2至3.8 g/t Au之间。苏联矿体的厚度从1米至3米不等。在40米（见图29）的最大深度处对几个区域进行有限的地下开采和采矿已经完成。产品的详细资料仍然是个未知数。

GEOLOGY AND MINERALIZATION: ADVANCED PROJECTS
6.1 Preamble
Exploration by Kaskad N in 2006 concentrated on the Skalistoe, Aleksandrovskoye and especially the Veseloe Prospects. The decision to explore these prospects was based on a combination of perceived geological merit, density of existing data and proximity to an access road. In addition, eight other prospects have been identified for exploration during 2007.
Based on historic data Kaskad N have concluded that only approximately 25 % of the 220 km2 Kuludjun licence has been explored to any degree.
6.2 Veseloe Prospect
The Veseloe Prospect is located in the southeast of the licence and is associated with the Bapern-Veseloe Fault Zone (Figure 5). The licence was extensively drilled and trenched in Soviet times (Figures 23 and 24) which resulted the delineation of a C1+C2 resource of 3.1 tonnes of gold and an additional undefined C1+C2+P2 resource of 1.9 tonnes of gold. Kaskad N completed a first stage infill drilling programme in 2006 for which most assay results are pending.
Mineralization occurs as a series of broadly north-south trending high grade lenses (>2 g/t Au) which are generally between three to five metres wide and between 50 to 150 metres long (Figure 23). Less commonly the high grade lenses are up to 10 metres wide. Mineralization dips to the east at approximately 50° although the dip of the high grade lenses may roll through steeper (ca. 60°) and shallower (ca. 30°) angles (Figure 24). In cross-section high grade lenses have a down dip extent of between 50 to 200 metres, and form several sub-parallel bodies which pinch and swell and may anastomose. Several sub-parallel high grade lenses which do not crop out at surface have been intercepted in the deeper drill holes at vertical depths of up to 250 metres below surface (Figure 24).
The higher grade lenses occur within an envelope of significant but lower grade mineralization defined by the 0.1 g/t Au contour (Figures 23 and 24). This envelope is between 10 to 75 metres wide at surface and forms a broadly north-northwest to south-southeast trending zone that is up to 400 metres long. The lower grade envelope bifurcates into a series of splays that are probably associated with fault splays of the main Bapern-Veseloe Fault. In cross-section the lower grade mineralization dips to the east at approximately 45° and is between 30 to 50 metres thick (Figure 24).
Unverified assay results from the Soviet drill holes indicate that the core of the Veseloe Prospect is significantly mineralized. The better intercepts from the surface to a depth of 150 metres in the line of section 08 (Figure 24) include: 26.4 metres at 11.6 g/t Au, 14.9 metres at 5.68 g/t Au, 11.4 metres at 7.03 g/t Au, 6.0 metres at 1.95 g/t Au and 8.1 metres at 5.4 g/t Au.
Existing cross sections indicate that the Veseloe ore body thins immediately to the north and south of the Veseloe open pit (cf. Figure 24 with Figures 25 and 26) and that thickness/grade intercepts are significantly lower. However, this may in part reflect the wider spacing of the Soviet drilling (ca. 50 to 200 metres between holes in the line of each section).
The 2006 Kaskad N drilling programme sensibly targeted near-surface mineralization with a series of closely spaced vertical and angled drill holes. Most assay results are pending. Gold assay results for channel samples taken by Kaskad N in oxide mineralization in the base of the Veseloe open pit (Figure 27) were significant and substantiate the Soviet data. Intercepts include 3.0 metres at 2.54 g/t Au, 2.2 metres at 4.95 g/t Au, 5.9 metres at 2.12 g/t Au, 6.0 metres at 3.3 g/t Au, 5.8 metres at 2.65 g/t Au and 8.5 metres at 1.95 g/t Au.

Soviet and Kaskad N trenches, Soviet exploration pits, and Soviet and Kaskad N drill holes are shown. Note the outline of the open pit.
6.3 Vladimirskoe-Preavednoe Zone
The Vladimirskoe-Preavednoe zone is located approximately two kilometres to the north-northwest of the Veseloe zone (Figure 6) and is hosted by the same regional fault system. The licence was trenched, pitted and drilled during Soviet times (Figures 28 and 29) and a C1-C2 near surface resource (Figure 30) of 2.3 tonnes and a PI resource of 1.6 tonnes of gold was defined at average grades of between 3.2 to 3.8 g/t Au. The thickness of the Soviet ore blocks varied from one to three metres. Limited underground development and mining was completed in several areas to a maximum depth of 40 metres (Figure 29). Details of production is unknown.
