Conquest identifies 20 targets from Golden Rose survey

2018-07-12 12:17 ET - News Release

Mr. Robert Kinloch reports

CONQUEST REPORTS FINAL RESULTS OF AIRBORNE GEOPHYSICAL SURVEY

Conquest Resources Ltd.'s final results and an interpretative report for the high-resolution, airborne geophysical survey on its Golden Rose property have been received and analyzed.

"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 electromagnetic 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 kilometres of VTEM data and horizontal magnetic gradiometer geophysical measurements were collected over the Golden Rose mine property, along transverse lines spaced 100 metres apart and tie lines spaced 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 in Aurora, Ont., in April, 2018. An interim processing report was delivered in May, 2018, with the final report delivered to Conquest in June, 2018 (Geotech, 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.

More specifically, the objectives of the VTEM survey were:

  1. To detect and map conductive zones related to gold mineralization and to provide geometrical and conductivity (or conductivity-thickness) estimates;
  2. To map and delineate sulphides and altered zones that could represent interest for gold mineralization;
  3. 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:

  1. To derive a detailed structural map of the property;
  2. To identify the structural control of mineralization (faults and contacts);
  3. To delineate magnetite-rich iron formations that may host or control gold mineralization;
  4. 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 1-D, 2-D and 3-D 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 3-D inversion yields a three-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 3-D 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 or mafic/ultramafic bodies. Moreover, magnetic data analysis focused on delineating alteration zones that may control, host and surround the mineralization (for example, secondary hematite or magnetite alterations).

Geophysical interpretation

The acquired magnetic data were transformed to provide detailed maps for comprehensive analysis, including 3-D magnetic inversion to obtain three-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 1-D electromagnetic inversion, 3-D MVI inversion, 3-D magnetic susceptibility inversion and 2.5-D 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 southeast dipping, and associated with highly magnetic features.

The 3-D 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 3-D inversion outcomes resulted into a detailed structural map of the Golden Rose property area, which include 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 m to 1,000 m) and generally striking in the northeasterly 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 km by 5 km in size, dominating the survey area, and stretching in the northeast 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 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 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, 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 20 conductors were identified and delineated, among which eight targets that occur 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.
