producer.
1. EXPLORATION IN ORAPA
Prospecting License (PL) 085, PL 210
1) Heavy concentrate sampling (30-50 litres) on detailed sites,
selected according to the results of mineralogical research.
Sampling grids - 200 x 200 m and 400 x 400 m.
2) Washing of heavy concentrate samples.
3) Mineralogical analyses of heavy concentrate samples in the field laboratory.
4) Sampling and washing are completed. Drilling will begin in early May.
PL 260
1) Diamond drilling on kimberlite pipe AK-21 of two boreholes to a total depth of 423 m.
2) Heavy concentrate sampling (30-50 litre) on detailed sites
selected by the results of the airborne magnetic survey.
3) Complex of ground geophysical surveys (magnetic, electric) to
delineate anomalies connected with kimberlites.
4) Transient Electro Magnetic soundings (TEM) on kimberlite
pipes AK-22 and AK-23 in order to get definitions of sizes and
morphology to a depth of 300 m.
5) Ground geophysical TEM works on kimberlite pipe AK-21 in
order to specify the morphology of the body to a depth of 150-300
m.
6) Studying the core of the boreholes.
7) Hard rock sampling of the core and selection of specimens for various analyses.
8) Hard rock samples treatment and washing.
9) Mineralogical analyses of the heavy concentrate and hard rock
samples in the field laboratory.
10) Diamond drilling, early core analyses and TEM works are
completed as is much of the heavy concentrate sampling. Reverse
Circulation Drilling and sampling will continue into May.
2. EXPLORATION IN GOPE
PL135, PL136, PL137 AND PL 235
1) Ground geophysical works and TEM soundings on anomalies.
2) Heavy concentrate sampling (250 litre) on geophysical anomalies.
3) Washing of heavy concentrate samples.
4) Mineralogical analyses of heavy concentrate samples in the field laboratory.
5) This work is ongoing.
The Alrosa-led team is applying state-of-the-art technology in
an innovative way. Mineralogical analyses of heavy concentrate
samples in the field laboratory allows us to accelerate results so
that our experts can focus the drill programme.
