DIOS EXPLORATION INC.: Major Favourable Diamond Indicator Counts at Hotish
MONTREAL, QUEBEC, CANADA--DIOS EXPLORATION INC. reports major and
significant till diamond indicator mineral counts on its
wholly-owned 530 sq. km HOTISH project, Quebec, showing highly
favourable chemistry. This new area located southwest of the Otish
Mountains extends the favourable diamond potential area to an
underexplored area for diamonds located right along the Renard 1-7
diamondiferous kimberlite - Beaver Lake kimberlite corridor. The
indicator chemistry is distinct from Beaver Lake. A cluster seems
delineated from several trains uncovered with several small
clustered geophysical anomalies up-ice on DIOS' property,
suggesting distinct sources from known pipes. The picking on 266
basal till samples processed for heavy minerals returned up to 128
diamond indicators per sample, an indication of the kimberlitic
source proximity. Microprobe testing is completed on 83 samples
but pyrope testing on all samples, returning 10 % harzburgitic
pyropes following Guerney's classification and 37 % G10 over G9
pyropes following Dawson & Stephen's classification. A multitude
of picroilmenites returned very high chromium and magnesium
contents, indicating very low oxygen fugacity in the mantle (very
good physical conditions to form diamonds), with perovskite rims,
indicating conditions to preserve diamonds in the raising chimney.
Such Cr-picroilmenite data mean the mantle under the earth crust
underlying the HOTISH project presents very low oxygen content,
necessary to form diamonds, reports M.-J. Girard, P.Geo, and the
perovskite rims show conditions to preserve them while raising up.
For instance, if magnetite (Fe3O4) rims had been encountered
instead of perovskite rims, it would have meant a high oxygen
content in the raising chimney thus possibly destroying the
diamonds back to graphite. We are very enthusiastic about these
results, especially as very fragile kimberlite minerals were also
observed in the rims, again indicating the proximity of the
kimberlitic source. Diamond mines worldwide are mainly hosted
within kimberlites. Research work at DIOS is focused on extensive
systematic basal glacial sand sampling and interpretation,
completed with geophysics which turn out to be a lot easier
south-west of the Otish than north of it due to the sedimentary
background enabling small intrusives to be more easily targeted
than in the highly magnetic background north of the Otish.
Due to the high significance of these results, partial follow-up
has already been carried out. The rest of the microprobe results
should be available shortly and follow-up geophysics and drilling
is planned for this fall and this winter, respectively. SIRIOS
RESOURCES INC. (TSX: SOI) is the major shareholder of DIOS.
