礦區(qū)工程施工說明-中英對照
序言
2006年，Kaskad N的勘探集中在Skalistoe,以及Aleksandrovskoye地區(qū)，特別是Veseloe 勘探前景。之所以決定集中在這些地方，主要是基于人們所認知的地理優(yōu)勢，現(xiàn)有的數(shù)據(jù)資料和允許進入的公路分布等因素綜合考慮的。此外，在2007年中，其他八個地區(qū)的勘探計劃也隨之確定下來。
依據(jù)歷史數(shù)據(jù)資料，Kaskad N 推斷220平方千米的Kuludjun獲許可地區(qū)僅僅開發(fā)了大約25％。
6.2 Veseloe 勘探前景
Veseloe勘探地區(qū)位于獲許可地域的東南部，與Bapern-Veseloe Fault地區(qū)（圖5）相接壤。在蘇聯(lián)時期（圖23和24）獲許可的地區(qū)曾大規(guī)模的鉆孔和挖溝，顯示有3.1公噸黃金的C1+C2資源和其他1.9公噸黃金未定義的C1+C2+P2資源。Kaskad N于2006年完成了第一階段填空鉆井項目，大多數(shù)的化驗結果尚未出來。
礦化出現(xiàn)是連續(xù)的，高等級晶體（>2 g/t Au）的趨勢從北到南延伸，寬度從3米至5米，長度從50米至150米（圖23）漸變。寬度長達10米的高等級晶體并不常見。礦化作用傾向于東方，大約50度角，雖然高等級晶體可能卷攏角度變得更陡（ca. 60°）和更淺（ca. 60°）（圖24）。橫截面高等級晶體有一定程度的下傾，在50至200米之間，形成亞平行主體。幾個亞平行高等級晶體不會在地表上顯露出來，而是被更深的鉆孔在地表50米以下（見圖24）被截斷。
根據(jù)0.1 g/t Au的等高線（見圖23和24）劃分，高等級晶體但低等級礦化出現(xiàn)在地表附近。 表面寬度在10至75米之間并形成一個從北西北至南東南的寬闊地帶，大約400米長。低等級的區(qū)域又形成小的分支并很可能與主要Bapern-Veseloe Fault的分支相結合。在橫截面中，低等級礦化傾向東面，角度約為45°，其厚度在30至50米之間（見圖24）。
未經(jīng)證實的蘇聯(lián)鉆孔處獲得的化驗結果表明Veseloe勘探前景的核心部分礦化情況明顯。從地表深度150米處開始截斷較好，按照截面8的線路進行（見圖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。
現(xiàn)有的橫截面表明Veseloe露天礦場的Veseloe礦石主體正在向北，向南逐漸變�。▓D24和圖25及26），且厚度/等級截斷相對較小�？墒沁@也折射出蘇聯(lián)鉆探的更大潛力空間（每個截面中的鉆孔見的距離為ca.50至200米）。
2006年，Kaskad N 鉆探項目將目標設定為近地表，使用一連串的近距離垂直和有角度的鉆孔完成鉆探。大多數(shù)的化驗結果尚未出來。Kaskad N在氧化礦化物中進行的黃金化驗結果是Veseloe露天礦場（見圖27）的基礎。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 地區(qū)
Vladimirskoe-Preavednoe地區(qū)位于Veseloe 地區(qū)（見圖6）的北西北部約2公里處。蘇聯(lián)時期擁有挖溝，開采和鉆井的執(zhí)照（見圖28和29）。該區(qū)域擁有2.3公噸黃金的C1-C2 近地表資源，及1.6公噸黃金的P1資源，平均等級在3.2至3.8 g/t Au之間。蘇聯(lián)礦體的厚度從1米至3米不等。在40米（見圖29）的最大深度處對幾個區(qū)域進行有限的地下開采和采礦已經(jīng)完成。產品的詳細資料仍然是個未知數(shù)。

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.
