Regional geochemistry defines new large-scale gold-in-soil anomalies for drilling in early 2019
- Several extensive and coherent MMI (mobile metal ion) gold-in-soil anomalies defined in new geochemistry results on 100%-owned areas at the East Cadillac Gold Project in Quebec, Canada:
- Legrand soil anomaly covers an area of ~3.4km x 1.3km, with a peak gold value of up to 22 times background. The anomaly has a similar pathfinder response and lies in a similar structural setting to Canadian Malartic (located ~70km to the west);
- Anderson soil anomaly covers an area of ~2.3km x 0.5km, with a peak gold value of up to 22 times background, located on a regional structure that hosts several large gold deposits to the west.
- The Legrand and Anderson anomalies represent the largest and most coherent anomalies found to date at the East Cadillac Project, and are entirely untested by drilling.
- The new high-priority targets are to be drill tested in the upcoming winter drill season, due to commence in January 2019.
PERTH, Western Australia, Oct. 25, 2018 /CNW/ - Chalice Gold Mines Limited (TSX:CXN) (ASX:CHN) is pleased to announce that it has defined several new, high priority, large scale, gold-in-soil anomalies at its East Cadillac Gold Project in Quebec, Canada, based on extensive surface geochemistry programs completed during the 2018 summer field season. The newly defined anomalies represent priority drill targets.
The recent soil, rock chip and geophysical programs were designed to expand regional data coverage and define new regional drill targets for the upcoming winter drilling season. The program builds on previous regional work, completed by Chalice in 2017, which included reconnaissance soil, rock chip and bark geochemistry as well as LiDAR, Aeromagnetic and 3D-IP geophysical surveys.
The results of the previous phase of work were used to design and execute the ~28,700m reconnaissance diamond drilling program completed in Q2 2018. This drill program identified two significant new zones of mineralisation at the Lac Rapides and North Contact Prospects and confirmed the potential for large-scale gold systems on the district-scale East Cadillac Project.
Chalice's Chief Executive Officer Alex Dorsch said: "The latest results confirm that East Cadillac is highly prospective for large-scale gold systems, and that the exploration toolkit we are applying gives us the best chance of vectoring towards a substantial discovery. This potential is further underlined by the prospective geological setting of the Project in the prolific Val-d'Or district, and its location along strike from several multi-million ounce gold deposits and mines.
"Since acquiring and consolidating the Project, we have systematically explored the area and made substantial progress in a relatively short period of time. We are very excited about the upcoming drilling program and we look forward to receiving results as our exploration activities ramp-up."
Surface Geochemistry and Geological Mapping Programme
The surface geochemical and geological mapping programs were completed during June-September 2018. A total of 1,504 mobile metal ion (MMI) soil samples were collected from both newly optioned/acquired claims and in-fill samples were collected over target areas defined from the wide-spaced 2017 soil sampling program.
The MMI soil sampling results have identified four new significant gold and pathfinder soil anomalies in areas subject to limited or no previous drilling (Figure 1).
Table 1 below summarises the main attributes of the geochemical anomalies. Importantly, the MMI gold anomalies are mostly associated with gold pathfinder elements, providing more evidence that the anomalies are related to bedrock gold mineralisation.

The Legrand gold-in-soil anomaly is coherent and covers a large surface area within a 5km x 4km area of anomalous arsenic and tungsten with minor bismuth. No bedrock geology outcrops were recognised in this area although aeromagnetic interpretation suggests that the Legrand anomaly overlies Pontiac Sediments which also host significant gold deposits elsewhere in the region including the Canadian Malartic gold deposit (endowment of >16Moz Au, not owned by Chalice), located approximately 70km to the WNW (Figure 2).
The Legrand anomaly overlies a zone of interpreted complex structure in an area of folded sedimentary rocks transected by thrust faults and intruded by felsic dykes, all of which suggests a favourable setting for orogenic gold mineralisation. In addition, the distribution of anomalous pathfinder metals in soils has a similar pattern of the metal zonation documented for the Canadian Malartic gold deposit which displays a zonation from proximal Au-W to distal Cs-Li-Tl. The Legrand anomaly has not been previously drill tested and is to be prioritised for drilling in the upcoming winter program.
The Anderson anomaly is a strong coherent gold-in-soil anomaly defined over a strike length of 2.3km and located about 2.5km north of the Larder Lake-Cadillac fault zone (LLCFZ). The east-west orientation is similar to other sub-parallel structures that host the Forsan gold deposit and other gold occurrences in the northern mafic succession. The anomaly is also to be prioritised for drill testing.
Rock chip sampling conducted during the 2018 field season has identified a 1.2km long zone of anomalous gold mineralisation, with assays up to 39g/t Au, located between 1-2.5km east of the recent Lac Rapides gold discovery. Gold mineralisation is associated with pyrite and/or arsenopyrite alteration in and around quartz veins in Banded Iron Formation. Limited historic drilling in this area has not intersected significant gold mineralisation however, given the strong association of gold with sulphide mineralisation, it is likely that the planned 3D-IP survey will allow a better definition of potential targets for testing.
Mobile Metal Ion Soil and QAQC Samples
Chalice sampling consists of 1504 mobile metal ion (MMI) soil and QAQC samples. Soil samples were collected from between 10 to 30 cm below surface. For every 20 samples collected a sand blank and field duplicate are inserted with all batches dispatched to the laboratory. Results are reported for all 1504 MMI soil samples.
MMI soil samples are processed as received. MMI soil samples are analysed by SGS Laboratories in Burnaby, British Columbia, Canada using laboratory technique GE_MMI_M which is a proprietary partial leach analysis.
Rock chip and QAQC Samples
Sampling includes 157 rock chip and QAQC samples. Samples collected from available outcrops which occur sporadically in the areas traversed. For every 20 samples collected a certified standard and blank are inserted with all batches sent to the laboratory.
Rock chip samples are dried and crushed to 70% passing 2mm, then riffle split to a 250gm which is pulverized to better than 85% passing 75 microns. Samples are analysed by ALS Laboratories in Val-d'Or, Quebec, Canada using laboratory techniques ME-MS61, Au-AA23, and Au-GRA21.
New aeromagnetic and LiDAR geophysical surveys were completed in June-August 2018 on newly acquired tenure to expand existing LiDAR and helicopter-based aeromagnetic coverage to the north and west of the main Larder Lake – Cadillac Fault (Figure 3). In conjunction with field geological mapping, these surveys have improved the Company's geological understanding of the known gold occurrences throughout the project area.
Proposed Future Work
A 3D-IP OreVision survey commenced in early October to extend existing coverage along the Larder Lake-Cadillac Fault for an additional ~7km east of the 2017 survey area (which covered ~16km of strike). The grid is also being extended to the south to cover the new Legrand anomaly to the south-east of Lac Rapides. Survey results are expected by the end of December.
The recently received results are being incorporated with the previously acquired data to design a diamond drill program planned for the upcoming winter drill season, to commence in January 2019. The program will be designed to test the new surface anomalies as well as testing several zones along strike from existing mineralisation. Existing targets will be refined and additional drill targets may be added to the program once the 3D-IP survey results are finalised in late December.
