Mosquito King
INTRODUCTION
The Mosquito King ~ silver, zinc, lead, copper, gold, cadmium property has been located by its current owner, Craig Lynes of Rich River Exploration Ltd. The claims cover known reserves of base metal, massive sulphide minerals.
LOCATION AND ACCESS
The Mosquito King claim is located on map sheet 82M/04E in the Kamloops Mining Division, British Columbia Canada. The claims are accessed via a good network of logging roads approximately 31 kilometres from the Trans Canada Highway and the main branch of the Canadian Pacific Railroad.
The claims are located in the highly mineralized Adams Plateau region of BC.
MOSQUITO KING ~ GENERAL LOCATION MAP
The Mosquito King claim and area has a very good network of existing logging and spur roads. The map below shows the network of access roads in the claim area. This excellent infrastructure should facilitate any future exploration in a cost effective and expeditious manor.
REGIONAL GEOLOGY
The area is underlain by favorable geology of the Eagle Bay Assemblage.
Consisting of arc and inter-arc type environments of intermediate to felsic volcanic and metamorphic equivalents, volcaniclastic grits and carbonates.
Transitional back arc units of sedimentary and metasedimentary rocks also occur in the immediate area.
These rock units are considered highly favorable for VMS and Sedex types of deposits.
The claim area is underlain by the Lower Cambrian part of the Eagle Bay Formation, consisting of siliceous and graphitic phyllites, phyllitic limestone, greenschist, chlorite schists and greenstone.
The metavolcanics and metasediments generally strike northeast and dip 10 to 40 degrees north- west. The rocks are cut by Late Cretaceous or Early Tertiary quartz- feldspar porphyry and mafic dykes with northerly trends.
PROPERTY
The 1073 hectare, Mosquito King, Ex-Spar and-Pet Silver group is centered on substantial outcroppings and showings of base and precious metals. Mineralization is mainly comprised of sulphides of silver, lead, zinc and copper, within metasedimentary and metavolcanic rocks on the north limb of the Nitwikwaia synform.
The showings occur within a dominantly metasedimentary succession of siliceous and/or graphitic phyllite, calcareous phyllite, streaky banded calc-silicate rock, limestone and quartzite. The metasediments are stratigraphically underlain by chloritic schist's and greenstone.
The mineralization occurs as layers, lenses and pods of semi- massive to massive sulphides, generally within a siliceous gangue. The dominant sulphides are pyrite, galena, sphalerite, chalcopyrite and pyrrhotite.
The sulphide horizons are generally well banded and conformable to the schistosity and to the bedding. Intense deformation of the rocks has caused discontinuity and marked variability in the widths of the sulphide horizons.
Massive sulphide horizons have been noted to thicken in the hinge zones of both isoclinal and recumbent NE to SW plunging synmetamorphic folds. Recommendations have been suggested, that further exploration should be directed toward the linear-plunging sulphide bodies. That are localized and thickened in medium scale fold hinges.
MOSQUITO KING ~ REGIONAL GEOLOGY MAP
EBGs ~ Dark to light grey siliceous and/or graphitic phyllite, calcareous phyllite, limestone, calc-silicate, cherty quartzite, minor green chloritic phyllite and sericite-quartz phyllite.
The Mosquito King showings occur as stringers, lenses and disseminations over an area of about 1000 by 500 metres. Mineralized widths vary from less than a metre to over 6 metres wide. An 18 foot (5.5m) wide sample assayed 1.4 oz/t Ag, 5.2% Pb, 7.2% Zn
The deposit character is concordant, disseminated and massive. It's classification is Sedimentary Syngenetic (Sedimentary Exhalative Zn-Pb-Ag)
Drill indicated reserves to date, in the area of the main workings are;
33,744 tonnes grading 13.3 grams per tonne silver, 0.83 per cent lead, and 2.09 per cent zinc.
An additional 4,716 tonnes grading 19.8 grams per tonne silver, 2.6 per cent zinc, and 1.38 per cent lead has also been defined.
Another massive sulphide layer on the property trends northeast and dips 30 to 40 degrees to the northwest. This layer can be traced approximately 600 metres to the north where it is folded and truncated by a fault.
Mineralization comprises sulphides of silver, lead and zinc within metasedimentary rocks.
The showings occur within a dominantly metasedimentary succession (EBGs) of siliceous and/or graphitic phyllite, calcareous phyllite, streaky banded calc-silicate rock, limestone and quartzite.
To date, the drill Indicated mineral reserves in this area are 11,157 tonnes grading 187.60 g/t silver, 10.56 % lead and 4.83 % zinc.
The Mosquito King claim also covers numerous other showings of
Noranda Kuroko type (VMS) massive sulphide Cu-Pb-Zn-Ag.
One such occurrence is the PET- SILVER BELL ~ (Minfile No. 82M 143)
This is comprised of a highly mineralized gossan, measuring over 100 by 10 metres. The metavolcanic rocks in this area consist of mainly calcareous chlorite schists, fragmental schists and greenstone derived from mafic volcanic and volcaniclastic rocks.
The massive sulphide showings occur within silicified tuffs and phyllites along a north 060 degree trend.
Mineralization at the Pet showings consists of massive pyrite, pyrrhotite, sphalerite, galena, and minor chalcopyrite.
A 2.1 metre wide sample assayed 2.99 per cent lead, 5.54 per cent zinc, 0.09 per cent copper, 38.4 grams per tonne silver and 1.8 grams per tonne gold.
Other occurrences within the Mosquito King claimed area are the Oro and the Pioneer Westville groups. These showings are similar in appearance to the Mosquito King zone. The showings are known to occur over a lateral distance of more than 370 metres.
This zone of massive lead zinc sulphides appears to occur in the same stratigraphic sequence. The mineral zones are located approximately 500 metres down dip from the Mosquito King workings.
Mineralisation in this area occurs in multiple horizons and is comprised of mostly fine grained massive base metal sulphides. However the main showing primarily consists of course grained galena and sphalerite.
A sample of this zone ran 50.8 ounces of silver to the ton.
LANDSAT IMAGE ~ MOSQUITO KING AREA
There are numerous other showings of base metal massive sulphides in the immediate area. Most of these showings are classified as either
Noranda Kuroko type (VMS) massive sulphide Cu-Pb-Zn-Ag.
Or Sedimentary Syngenetic, Sedimentary Exhalative (Sedex Zn-Pb-Ag)
Previous work programs on this property have delineated several
geochemical and geophysical anomalies.
Further exploration has been recommended and is warranted to follow up on these targeted areas.
