- 20 Geophysical Targets identified at Golden Rose
Property
- New insights into structural context and gold mineralization
prospectivity
TORONTO, July 12, 2018 /CNW/ - Conquest Resources Limited
(TSX-V: "CQR") reports that the final results and interpretative
report for the high-resolution, airborne geophysical survey on its
Golden Rose property have been received and analysed.
"Based on the combined magnetic and electromagnetic data
interpretation outcomes, at least 20 targets associated with
magnetic and EM conductive anomalies favourable for gold
exploration were identified and delineated within the Golden Rose
Property. Among these targets, there are eight highly favourable
targets that are prioritized for future follow up." (Geotech
Report, 2018).
The helicopter-borne Versatile Time Domain Electromagne3tic
(VTEM™ Plus) and Aeromagnetic Geophysical Survey was carried out by
GEOTECH Ltd., over the Golden Rose Mine project area in
March 2018.
During this survey, in total, 179-line kilometers of VTEM data
and horizontal magnetic gradiometer geophysical measurements were
collected over the Golden Rose Mine property, along transverse
lines spaced at 100 m apart and tie
lines spaced at 1,000 m apart, using
an Aerospatiale A-Star 350 B3 helicopter, owned and operated by
Geotech Aviation Ltd.
Data processing was performed by Geotech Ltd in Aurora, Ontario in April 2018. An interim processing report was
delivered in May 2018 with the final
report delivered to Conquest in June
2018 (Geotech Ltd, 2018).
GOLDEN ROSE – GEOPHYSICAL SURVEY OBJECTIVES
The primary objectives of the helicopter-borne geophysical
survey and the interpretation of the acquired data were to derive
detailed lithological and structural maps of the Golden Rose Mine
project area and to delineate new favourable areas for detailed
exploration of gold and/or other mineralization and related
alteration zones (anomaly map provided at:
www.conquestresources.com ).
More specifically, the objectives of the VTEM survey were:
- To detect and map conductive zones related to gold
mineralization and to provide geometrical and conductivity (or
conductivity-thickness) estimates;
- To map and delineate sulphides and altered zones that could
represent interest for gold mineralization;
- To provide a resistivity (conductivity) distribution of the
near surface area.
The data interpretation objectives were to derive a detailed
structural map of the Golden Rose property, which highlights the
structural control of mineralization and to delineate favourable
target-areas for further exploration of gold mineralization, and
related sulphides and alteration zones.
More specifically the data interpretation objectives were:
- To derive a detailed structural map of the property;
- To identify the structural control of mineralization (faults
and contacts);
- To delineate magnetite-rich iron formations that may host or
control gold mineralization;
- To identify new favourable target-areas for further exploration
of gold mineralization.
To achieve these goals the interpretation efforts were based on
magnetic and VTEM data transformations and inversion results and
their integration with known mineralized occurrences and geological
information.
Background to airborne geophysical surveys
Airborne magnetic surveys have been used for a long time as a
cost-effective tool for detailed geological mapping and mining
exploration. Advances in magnetic data processing and the
availability of robust inversion software designed to invert the
data in 1D, 2D and 3D dimensions have helped advance magnetic
prospecting techniques as an effective tool for lithological and
structural mapping in general, and mineral exploration in
particular.
The use of standard and advanced filtering techniques utilizing
Fast Fourier Transforms provides a good understanding of the
structural framework of the study area, while 3D inversion yields a
tri-dimensional distribution of the magnetic properties for the
subsurface to help detect zones of interest including,
fault-controlled mineralization, alteration zones, as well as
magnetite-rich and magnetite-bearing mineralization.
The main objectives from the magnetic data analysis and
inversion results are to derive a detailed structural analysis of
the property, a 3D distribution of the magnetic properties of the
subsurface area, and to provide geometric and magnetic parameters
of the magnetic sources such as mafic rocks, and magnetite-bearing
and magnetite-rich structures that may either host or control gold
mineralization.
One of the primary goals during the structural interpretation of
the magnetic data was to identify and delineate structures and
faults that may control either gold mineralized and gold bearing
magnetite-rich Banded Iron Formation ("BIF") or
mafic/ultramafic bodies. Moreover, magnetic data analysis
focused on delineating alteration zones that may control, host, and
surround the mineralization (e g., secondary hematite or magnetite
alterations).
GEOPHYSICAL INTERPRETATION
The acquired magnetic data were transformed to provide detailed
maps for comprehensive analysis, including 3D magnetic inversion to
obtain 3-dimensional magnetic susceptibility and magnetization
amplitude distribution of the subsurface area, as well as
identification of magnetic structures associated with
magnetite-rich BIF and mafic/ultramafic rocks suspected of either
controlling or hosting gold and base metal mineralization.
The VTEM data have been analyzed and inverted using various
algorithms based on 1D EM inversion, 3DMVI inversion, 3D magnetic
susceptibility inversion, and 2.5D Maxwell plate modelling which
confirmed the presence of numerous shallow and deep-seated
conductive zones presenting an interest for the exploration of gold
mineralization and related sulphide and/or alteration zones.
Potential gold mineralized zones highlighted from the inversion
results are suggested to occur at shallow depths, all generally
south-east dipping, and associated with highly magnetic
features.
The 3D magnetic interpretation and inversion results provided a
detailed structural map of the property, which includes the
outlines of the magnetic structures and the main faulting systems
that crosscut the survey area. The mapped highly magnetic
structures are suggested to present a link to BIF or
mafic/ultramafic rocks (komatiites) that represent the main
host/control of gold mineralization and related sulphides, and
associated alteration zones.
The combined analysis of the transformed maps and the 3D
inversion outcomes resulted into a detailed structural map of the
Golden Rose property area which includes combined results from
magnetic and VTEM data inversions and their interpretation on which
known gold mineralized zones and previously mapped lithological
units are plotted for correlation purposes.
The results suggest the presence of numerous highly magnetic
features characterized by various lengths (100-1000m) and generally striking in the north-eastly
direction. These features are interpreted to suggest a direct link
to BIF, and possibly to mafic/ultramafic rocks. Moreover, the
inversion results also suggest the presence of a broad magnetic
zone measuring approximately 1.5 × 5 km in size, dominating the
survey area, and stretching in the NE direction. This feature is
suggested to be associated with a deep-seated magnetite-rich or
hematite-rich alteration zone that surrounds the highly magnetic
features.
Based on the combined magnetic and electromagnetic data
interpretation, at least twenty (20) targets associated with
magnetic and EM conductive anomalies and favourable for gold
exploration were identified and delineated within the Golden Rose
Property. Among these targets eight (8) are regarded as highly
favourable and are prioritized for additional mapping, geochemical,
and diamond drilling follow-up.
GOLDEN ROSE – GEOPHYSICAL SURVEY CONCLUSIONS
Based on the combined magnetic and VTEM inversion and
interpretation results and their integration with known mineralized
occurrences and available geological information, new insights into
the structural context and gold mineralization prospectivity of the
Golden Rose Mine property are suggested. Several targets for gold
mineralization have been identified for further follow-up work
within the Golden Rose Mine Property.
The newly identified conductive targets occurring within
favourable geological context (lithological and structural control)
are considered as potential candidates for gold mineralization
associated with magnetic structure (magnetite-rich BIF and or
mafic/ultramafic rocks).
RECOMMENDATIONS
Based largely on the encouraging VTEM and magnetic data
interpretation results by Geotech Ltd., the following
recommendations for follow-up work on the Golden Rose property are
suggested:
- Integrate the newly obtained results with all available
geological, geochemical, and drilling information to better
prioritize the newly identified exploration targets;
- Carry out detailed soil/till/rock geochemistry over the
identified geophysical anomalies;
- Drill-test the recommended first-priority targets;
- Evaluate the potential advantages of carrying out detailed
ground geophysical follow-up surveys within the selected gold
target to better define the anomalies.
The VTEM data helped map and detect numerous conductive and
chargeable zones that may be linked to gold mineralization and/or
related sulphides and alteration zones. At least twenty (20)
conductors were identified and delineated, among which eight (8)
targets that occurr in coincidence with strongly magnetized zones
and represent prospective locations for gold-sulphide
mineralization and are considered as the most favourable areas for
mineral exploration.
