Gravimetric Survey on the Bench Marks of the Levelling Line
In spring 2007, we performed a relative gravimetric survey to determine gravitational acceleration in 45 bench marks of the levelling line.
The Company has commissioned a detailed gravimetric survey
of the Round Top project area and it is expected that the combination of the gravimetric survey
with the aerometric survey will better define drill targets both for additional masses of mineralized rhyolite and for possible limestone-fluorite-rare earth minerals replacement mineralization in the favorable limestone at depth.
Favorable results drives decision to commission close-spaced gravimetric survey to assist in identifying new exploration targets
Because the results of the magnetic survey are so favorable, we have commissioned a close spaced gravimetric survey of the area to even further define geologic structure and to guide in additional exploration drilling beyond our current program.
Waseco plans immediate exploration work consisting initially of an airborne radiometric and gravimetric survey
followed by ground mapping and drilling of the targets outlined above plus any new targets identified from the airborne survey.
This should be followed by geophysical surveys, with airborne magnetic and electromagnetic survey, if available and / or ground geophysics, including the two areas and a gravimetric survey
of the target areas and the surrounding area.
The Bouguer anomaly evaluated on the base of gravimetric surveys
(LAka, 1981) is presented in Figure 1.
Aerial and terrestrial gravimetric surveys
were carried out in the Gibraltar Strait Zone both in the northern and the southern sides between Spain and Morocco.
The GPS, leveling, gravimetric surveys
were carried on the benchmarks (Goral et al.
The data base includes - but is not limited to - low altitude magnetic surveys of the entire region, local gravimetric surveys
, bedrock surface sampling by pneumatic drilling, geologic mapping, cross sections of previous mining areas, and mine records.
Geophysical work will include both induced polarization (IP) and gravimetric surveys
and will test a large area with no rock outcrop peripheral to outcropping mineralization that is thought to have excellent potential for additional replacement-style mineralization and/or stratiform massive sulphide lenses.
