Q2 Metals (TSX-V:QTWO) will conduct further metallurgical testing after releasing the results of initial testing on drill core samples collected from the 2024 program on the Cisco Lithium Project.
Initial mineralogical work was completed by SGS Canada on 16 drill core analytical pulp samples of pegmatite collected across seven drillholes at the Cisco Project. The purpose of the mineralogy work was to provide a preliminary characterisation of the lithium pegmatite at Cisco and to orient the direction of subsequent mineral processing test work.
All samples were analysed by X-ray diffraction (XRD) for quantitative modal mineralogy. The samples that were submitted had representatively low, mid and high grades, with individual samples containing lithium between 0.53% and 3.8% Li2O.
The results of the XRD analysis indicated average spodumene content of 17% within sample results, ranging between 6% and 39%. The remaining minerals in the samples include quartz, albite, microcline, muscovite and occasionally biotite and/or beryl.
To follow-up the initial XRD analysis, samples are currently being prepared for additional metallurgical test work, including heavy liquid separation (HLS), dense media separation (DMS), magnetic separation, and flotation.
The primary objective of the follow up preliminary metallurgical program is to evaluate the beneficiation of the currently defined mineralized zone at the Cisco Project with a traditional lithium pegmatite flowsheet. The goal of the proposed work is to produce a spodumene concentrate of greater than 6% Li2O with low iron content, at a maximum lithium recovery.
VP Exploration Neil McCallum says all minerals are present in common rations compared to other pegmatites in the James Bay Lithium District. Cisco is located within the greater Nemaska traditional territory of the Eeyou Istchee James Bay, Québec, Canada.
“Having spodumene as the only primary lithium-bearing mineral verified with a high-precision method like XRD is an important milestone for the Cisco Project, verifying our core observations of coarse-grained spodumene,” says McCallum.
“We will be conducting further metallurgical testing of the mineralised zone at the project to understand its amenability to HLS and DMS flowsheet work.”
Q2 Metals CEO Alicia Milne and VP of Exploration Neil McCallum will present live at the Metals and Mining Virtual Investor Conference on 12 February.
The company will be exhibiting at this year’s Prospectors & Developers Association of Canada (PDAC) event being held from 2-5 March in Toronto, Canada.
The annual award winning convention brings together up to 30,000 attendees from over 130 countries for its educational programming, networking events, as well as business and investment opportunities.
