Calidus Resources works to establish a new ore source for its Warrawoona Project, WA

Gold producer Calidus Resources (ASX:CAI) is aiming to establish its Felix discovery as an ore source for its Warrawoona Gold Project in Western Australia. 

The $112.40 million market capitalisation company has recently completed a second-stage soil sampling program at Felix, with 800 samples collected and analysed on-site using the Portable PPB process. 

This program aimed to better define the magnitude and strike extent of soil anomalies in the area and will be used to inform a future infill reverse circulation (RC) drilling program across nearly 2km of the Blue Spec fault zone, which is yet to be drill tested and lies west of the area covered by 2022 scout drilling. 

Meanwhile, at Marble Bar, follow-up work to previous drill programs will include drilling southern extensions of the reef that were not previously drilled in 2022. These results are aimed to provide the basis for a decision on establishing a Mineral Resource Estimate (MRE). 

This announcement comes after Calidus received ‘strong’ drilling results from its Felix discovery that support its strategy to grow the inventory, production, and mine life at the Warrawoona Project by defining and developing deposits within trucking distance of the project. 

Results include drillhole 23GORC052 with 15m @ 2.19g/t Au from 22m, including 1m @ 19.82g/t Au from 31m; and drillhole 23GORC039 with 10m @ 1.56g/t Au from 16m, including 2m @ 4.11g/t au from 23m. 

Commenting on the results, Calidus Resources Managing Director Dave Reeves says: “These results support the prospect of Felix becoming a source of ore for Warrawoona, enabling us to increase mine life and leverage the infrastructure. 

The results will be used in conjunction with the results from a soil sampling program currently underway to plan the next stage of drilling to determine the likelihood of a mineral resource amenable to open-pit mining. 

Results from the program will be used to test the potential for high-grade ore feed for Warrawoona, which is only 25km away”

At Marble Bar, planned drilling is designed to test the thickness and grade continuity of a high-grade portion of the quartz reef and to test down-dip and along-strike extensions of the reef that are currently open. Results from the program will be used to test the potential for high-grade ore feed for Warrawoona, which is only 25km away.”

The drilling program completed was designed to follow up on initial results by testing the potential for Felix to host a shallow mineral resource. Results from the program have demonstrated the geometry of the mineralised horizons and their strike continuity. 

Calidus says this was an important step because there was no previous drilling or substantive exploration work in the Felix discovery area. 

The Felix discovery is located 65km from the Warrawoona Project and 5km from Calidus’ Blue Spec deposit. 

Calidus Resources is a gold exploration and development company with a portfolio of assets in the Pilbara Goldfields region of Western Australia. The company’s projects include the Warrawoona Gold, Blue Spec Gold, and Spear Hill Lithium projects. 

As of 31 March 2023, the company had $8.8 million cash and cash equivalents at hand after a $15 million debt repayment and $2.6 million spent on development and growth activities, according to its latest quarterly report published on 27 April 2023.
