Drilling planned to commence next month to test multiple new ground-based EM targets
Highlights
Moving-Loop Electromagnetic (MLEM) survey completed over four previously identified airborne EM targets on 100%-owned hard-rock mineral rights tenure:
Cluster of strong, discrete, late-time EM conductors identified at the Ephesus Target; and
Two shallow conductors identified with ~5,000 Siemens conductance overlying Ruins Dolerite outcrop – a known host of high-grade magmatic nickel sulphides in the district.
Airborne EM program completed over a previously untested ~8km strike length of Ruins Dolerite outcrop within the King Sound Area (Chalice earning an 85% JV interest):
New strong, discrete EM conductor identified at King Sound Target; and
Additional MLEM planned to refine target for possible inclusion in maiden drill program.
Maiden RC drill program planned to commence in September to test the two high-priority Ephesus EM conductors and potentially additional targets defined at King Sound.
King Leopold Orogen continues to demonstrate the potential for new high-grade nickel sulphide discoveries.
Chalice well positioned with a ~1,800km2 land-holding in this frontier nickel sulphide province and >A$30 million in working capital and investments.
Nickel market outlookexceptionally strong, driven by electrification across multiple industries and increasing demand for class-1 nickel for use in lithium-ion batteries.
PERTH, Western Australia, Aug. 20, 2019 /CNW/ - Chalice Gold Mines Limited ("Chalice" or "the Company") (ASX: CHN| TSX: CXN | OTCQB: CGMLF) is pleased to advise that it has identified several highly prospective EM conductors from recent ground-based and airborne EM geophysical surveys over the King Leopold Nickel Project in the west Kimberley region of WA (Figure 1).
Commenting on the results, Chalice's Managing Director Alex Dorsch said: "Our first program of ground-based and airborne geophysics has delivered encouraging early-stage results. Given we have only owned the project for a couple of months, we have made great progress on the project in a short timeframe."
"Ground-based EM surveys have confirmed several strong, shallow EM targets at Ephesus which, considering their proximity to the high-grade Merlin nickel sulphide Prospect, may represent massive sulphides. The cluster of strong shallow conductors overlying Ruins Dolerite outcrop represent priority targets for our upcoming drilling program."
"The recently completed airborne EM survey over the previously untested King Sound Area has also identified promising additional targets that will be further refined with ground-based EM surveys ahead of the drill program. We are very much looking forward to the start of RC drilling next month."
All high-priority targets identified are located within or near outcropping / sub-cropping Ruins Dolerite, a known host rock of high-grade magmatic nickel sulphides in the province.
Ground-based EM Results
A MLEM survey was completed over E04/1169, where Chalice owns 100% of the hard-rock mineral rights. The program followed up on four priority targets identified from the previous "Xcite" Airborne EM survey in 2018, with the objective of defining drill-ready, discrete, late-time EM conductors.
The MLEM survey included 125 stations over 12 lines and successfully generated nine conductive plates. Two high priority, strong, discrete and shallow EM conductors were identified and modelled at the Ephesus Target (Figure 2).
Conductors A and B have a strong conductance of ~4,800 and ~5,000 Siemens respectively, and are modelled at a shallow depth within an extensive suite of Ruins Dolerite. The interpreted source of the conductors is massive sulphides.
Conductors C to F are modelled with low to moderate conductance (<3,000 Siemens) and based on field reconnaissance are likely sourced from pyritic and/or graphitic units. They are therefore considered to be lower priority for follow-up drill testing.
All conductors will be field checked in the coming weeks in order to locate any surface expressions of the conductive sources.
Table 1 below summarises the properties of each significant conductor identified to date at the Ephesus Target.

These parameters have been produced from Maxwell geophysical modelling software, and are approximations based on ground based EM surveys only.
Chalice is encouraged by this first phase of MLEM, with two highly prospective drill targets already identified in a similar geological setting to the nearby Merlin Prospect owned by Buxton Resources (ASX: BUX) and Independence Group (ASX: IGO). Buxton's Merlin Prospect has had several phases of EM and drilling, with drill intercept grades up to 8% Ni reported.
Airborne EM Results
A SkyTEM airborne EM survey was recently completed over E04/2299 and E04/2325, where Chalice is earning an 85% JV interest. This survey is the first geophysical program to be completed over this area, which includes an ~8km outcropping strike length of prospective Ruins Dolerite.
A total of 1,394 line kilometres were flown at 150m line spacing, which generated clear and high-quality EM anomalies in a highly resistive environment.
Several discrete and strong mid-to-late time EM anomalies were identified, coincident with the outcropping ridge of Ruins Dolerite, which require immediate field checking (Figure 3).
Forward Plan
A heritage survey is planned in late August on the southern areas of E04/1169 as well within key areas of interest on E04/2299 and 2325. Field reconnaissance and further ground EM will then commence in early September at the King Sound Area, as well as at two additional targets on E04/1169.
RC drilling at the Ephesus Target and potentially additional King Sound ground EM targets is expected to commence in mid-late September. The program may be expanded subject to the results of the next phase of reconnaissance and geophysics.
Sampling Techniques
No drilling data to be reported
Khumsup Geophysics was contracted to complete the Moving Loop Electromagnetic (MLEM) survey.
SkyTEM Australia was contracted to complete the Airborne Electromagnetic (AEM) survey.
MLEM survey data was collected with 200x200m loops and 50 to 100m stations spacing using a Smartem 24 system and FluxGate 3 component receiver in a 200m offset Slingram configuration. Z, X and Y component data were collected at a base frequency of 1Hz.
AEM survey was heli-borne, with 150m line spacing using a high current and low base frequency (12.5Hz) system
Maxwell software was utilised to process and model the MLEM and AEM data.
Modelling and interpretation of the EM survey geophysical data was undertaken by Armada Exploration Services
MLEM data locations are surveyed with a handheld GPS with an accuracy of +/-5m which is considered sufficient for MLEM data location accuracy.
Chain of Custody is managed by the Company's geophysical field contractor and geophysical consultants. The data is transferred daily and is QA/QC checked by a qualified (i.e. Member of ASEG) geophysicist.
The King Leopold Nickel Project covers an area of ~1,800km2 in the west Kimberley region of Western Australia (Figure 4). The Project covers several known areas of Ruins and Hart Dolerite, which are both considered highly prospective for magmatic nickel sulphides as well as other related metals (Cu, Co and PGEs).
The Ruins Dolerite has been demonstrated to host high-grade nickel sulphides (drill intercept grades up to 8% Ni) after the Merlin discovery in 2015 by Buxton Resources (ASX: BUX). Buxton has since executed two option and earn-in joint venture agreements with Independence Group (ASX: IGO) and large-scale exploration activities are underway in the region. The JV has also substantially increased its licence holding in this frontier province.
Chalice's King Leopold Nickel Project is a combination of several 100% owned exploration licences, 100% owned hard rock rights as well as an earn-in agreement (earning up to 85%). Field activity on the Project commenced in late June 2019, initially focusing on areas immediately adjacent to the Merlin discovery.
