Canada: Dotted Lake Property - Geophysics Survey Update
Panther Metals PLC (LSE:PALM) the company focused on mineral
exploration in Canada and Australia, is pleased to announce the
receipt of the processed high-resolution Airborne Electromagnetic
("AEM") and Magnetics geophysics survey data and associated maps
and report over the Dotted Lake Property on the north limb of the
Schreiber-Hemlo greenstone belt in Ontario, Canada.
Highlights
-- Processed data, mapping and report received for the Dotted
Lake Property high-resolution airborne electromagnetic ("AEM") and
magnetics ("Mag") geophysics survey (announced 13 October
2020).
-- Canadian airborne geophysics survey company Prospectair
Geosurveys ("Prospectair") flew the 818 line-km survey utilising
helicopter-borne sensors over a series of seven flights conducted
between 9(th) -11(th) December 2020. Prospectair also successfully
flew geophysics over Panther's Big Bear Project in June 2020.
-- A total of 138 geophysical anomalies have been identified by
the survey, these are now being evaluated and prioritised for
follow-up investigation.
-- Dotted Lake Property is located 93km east of Panther's Big
Bear Gold Project, 18km north of the Barrick Hemlo Mine and 34km
north-east of the Marathon Palladium Project where a proposed open
pit mine for palladium, platinum, gold and copper is currently
undergoing permitting and planning by Generation Mining,
Darren Hazelwood, CEO, commented:
"We are delighted to announce the receipt of the processed
airborne geophysics survey data, maps and report for the Dotted
Lake Property in Canada. The survey was flown by Prospectair, the
same company who flew AEM and Mag over the Big Bear Gold Project
survey in June of 2020.
The processed data and report recommendations for the Dotted
Lake survey are now being evaluated and will be used to help direct
further work in addition to the drilling that is already planned
for the property".
Survey Technical Details
The Dotted Lake Property area was flown with traverse lines at
50m spacing and control lines spaced every 500m. The survey lines
were oriented 162degN with control lines oriented perpendicular to
traverse lines. The nominal flying height aimed by the pilot was
85m, but the active topography resulted in the average helicopter
height above ground of 86m, with the mag sensor and receiver coil
at 61m, and the transmitter loop at 36m above the
ground. The average survey flying speed (calculated equivalent
ground speed) was 31.1m/s.
Airborne Magnetometers: Geometrics G-822A
Both the ground and heliborne systems use a non-oriented
(strap-down) optically-pumped Cesium split-beam sensor. These
magnetometers have a sensitivity of 0.005 nT and a range of 15,000
to 100,000 nT with a sensor noise of less than 0.02 nT. The
heliborne sensor is mounted in a bird made of non-magnetic material
located 25 m below the helicopter when flying. Total magnetic field
measurements are recorded at 10 Hz in the aircraft. The ground
system is recording magnetic data at 1 sample every second with a
GSM-19 Overhauser base-station magnetometer.
Real-Time Differential GPS: Omnistar DGPS
PROSPECTAIR uses an OmniStar differential GPS navigation system
to provide real-time guidance for the pilot and to position data to
an absolute accuracy of better than 5 m. The Omnistar receiver
provides real-time differential GPS for the Agis on-board
navigation system. The differential data set is relayed to the
helicopter via the Omnistar network of geosynchronous satellites
for the survey location. The receiver optimises the corrections for
the current location.
Airborne Navigation and Data Acquisition System: Pico-Envirotec
AGIS-XP system
The Airborne Geophysical Information System (AGIS-XP) is an
advanced, software driven instrument specifically designed for
mobile aerial or ground geophysical survey work. The AGIS
instrumentation package includes an advanced Satellite navigation
(GPS), real-time flight path information that is displayed over a
map image (BMP format) of the area, and reliable data acquisition
software. Thanks to simple interfacing, the radar and barometric
altimeters, the RSI spectrometer, the Geometrics magnetometer and
the ProspecTEM time-domain electromagnetic system data are easily
integrated into the data acquisition system and digitally recorded.
Automatic synchronisation to the GPS position and time provides
very close correlation between data and geographical position. The
AGIS is equipped with a software suite allowing easy maintenance,
upgrades, data QC, and project and survey area layout planning.
Time-Domain Electromagnetic System: ProspecTEM
Prospectair Geosurveys significantly modified and improved the
Emosquito II that was built by THEM Geophysics of Gatineau (Québec)
to develop ProspecTEM. It is a powerful light-weight system adapted
for small size helicopters and easy manoeuvrability enabling the
system to be flown as close to the ground as safely possible and
ensuring maximum data resolution. Advanced signal processing
technique and a full processing package was developed in house to
optimise the ProspecTEM data.
The ProspecTEM system employs a transient or time-domain
electromagnetic transmitter that drives an alternating current
through an insulated electrical coil system. The towing bridle is
constructed from a Kevlar rope and multi-paired shielded cables. It
is attached to the helicopter by a weak link assembly. An onboard
harness with outboard connectors mounted on a plate allows for
quick disconnection or connection of the exterior elements. The
system uses a 4 KW generator and a large condenser to transmit
alternating 2.75-ms half sine pulses with intervening off-times of
13.916 ms electric pulse, 60 pulses per second.
