Sama Resources Québec Completed a 1,494 line-km HELITEM2 Survey at the Lac Brulé Nickel-Copper Project in the Province of Québec outlining several high conductivity zones.
- A 1,494 line-km HELITEM2 survey outlined several high conductivity-thickness (CTP) zones characterised with elevated conductivity levels near the discovered gossan and along an interpreted 10 km-long folded amphibolite unit.
- Based on these excellent results, a large exploration program is planned for summer 2022 at the Lac Brulé and Lac Brennan properties. Exploration works will include geological mapping and sampling, ground geophysical survey aimed at drilling priority targets by the fall of 2022. An existing vast network of forestry roads and bridges will greatly facilitate access for all our exploration works.
Montréal, Quebec, March 22, 2022 – Sama Resource Inc. (“Sama” or the “Company”) (TSX-V: SME | OTC-PK: SAMMF) is pleased to report that Sama Resources Québec Inc. (“SRQ”) a fully owned subsidiary of the Company has announced the completion and interpretation of a HELITEM2 electromagnetic and magnetic helicopter geophysical survey of 1,494 line-kilometres (line-km) at the new Lac Brulé nickel-copper property in the Province of Québec, Canada (Figure 1).
As a follow-up on the new gossan discovered in May 2021 (see Press Release 2021-06-16)*1,SRQ commissioned Xcalibur Multiphysics (MPH) Canada Inc. for a HELITEM2 electromagnetic survey supplemented by a high-sensitivity cesium magnetometer. One block of claims (390 claims) was flown between December 5 and December 14, 2021. The survey coverage consisted of 1,374 km of traverse lines flown with a spacing of 200 and 100 metres (“m”) and 119 km of tie lines with a 2000 m spacing.
Figures 2 to 5 show Xcalibur’s final compilation outlining several high conductivity-thickness-product (“CTP”) areas grading 5 to 6 on the Conductivity Grade scale (Table1). Highest Conductivity Grade and CTP, outlined by the late off-time channel/gates (Figures 2 & 5), are located next to the discovered gossan. Figure 6 shows the rooted EM response down to 600 m from surface. Detailed Interpretation and targets modeling will be performed by M. Joel Simard, P. Geol./Geoph based in St-Donat, Quebec province, Canada.

“While we are fully committed at exploring and developing our Ivorian Samapleu Ni-Cu-PGM assets with our partner Ivanhoe Electric, Sama is demonstrating its ability at finding new highly prospective grounds worldwide in totally virgin territories.” said Marc-Antoine Audet, Ph.D, P.Geo and CEO of Sama Resources Inc. Dr. Audet is continuing by saying “SRQ’s 100% owned Lac Brulé project is only 5 hours driving north of Montreal, Québec Province, which greatly facilitate our upcoming explorations programs”
No historical prospecting or ground exploration had been reported from the Lac Brulé area prior to SRQ. The past-producing Renzi nickel-copper mine is the closest mining activity with historical information available. The Renzi mine is located 48 km east-southeast of the Lac Brulé property. The Company is targeting possible accumulations of Ni and Cu mineralisation at Lac Brulé that could be of similar nature to that at the Renzy mine, Voisey Bay Ni-Cu mine and at other well-known Ni-Cu deposits in Canada and worldwide.
Geophysical HELITEM2 electromagnetic Program
The HELITEM2 system is composed of a 40 m cable to which is attached the transmitter loop. The receiver platform and the receiver coil are located at the centre of the 35 m diameter transmitter loop approximately 0.1 m above the centre of the transmitter plane. The real time navigation GPS antenna is on the tail boom of the helicopter. The barometric altimeter, radar altimeter, laser altimeter, video camera and data recorder are all installed in the helicopter. GPS antennae are attached to the transmitter loop to give positional information and transmitter orientation.
The survey used a 7.5 Hertz (“Hz”) one half cycle of the HELITEM2 system is made up of a square pulse (on-time) of approximately thirty-four milliseconds in duration followed by approximately thirty-four milliseconds of off-time before the pulse is repeated with the opposite polarity. After acquisition the measured data are windowed into twenty-five ranges called “gates”. Gate widths increase as time after turn-off increases because as the energy from the transmitter decays a wider sample must be taken to get a valid average. The position of the first off-time gate is selected after examining several flights of data and is as close to the transmitter turn off as possible. The power of the pulse causes eddy currents in the system after the turn off and the first off-time gate cannot start until these have died away. The earliest data has had less time to penetrate the subsurface and so contains information from the near surface. Detailed technical information on the survey is available on Sama’s website.
Xcalibur MPH selected electromagnetic (“EM”) anomalies automatically using proprietary software from both X and Z components using the fourth off-time gate and a threshold of 100 nT/s. These automatically generated anomalies were then examined in profile form for each line against the X & Z EM responses, decay information, magnetic responses, altimeter readings and flight path videos removing those not considered valid and adding additional anomalies missed by the threshold. For each anomaly the conductor type was interpreted and assigned to each anomaly. After reviewing all anomalies, the following parameters were associated with each anomaly using the data for the fourth off-time gate and where applicable: conductivity-thickness-product (CTP) (Table 1), amplitude of EM response, last off-time channel with an anomalous response, time constant, apparent depth and dip.

2022 Exploration Program
SRQ will continue surface exploration at the Lac Brulé and Lac Brennan properties. Exploration works will include geological mapping and sampling, ground geophysical survey aiming at drilling priority targets by the fall of 2022. An existing vast network of forestry roads and bridges will greatly facilitate access for all our exploration works.
