Azure has received further hints about the true scale of lithium mineralisation at its Andover project in WA after step-out drilling returned more broad lithium intercepts.

The latest assays of 90.2m grading 1.23% Li2O (ANDD0214) and 63.7m at 1.15% Li2O (ANDD0210) have demonstrated the excellent continuity of broad zones of lithium mineralisation over a strike length of over 1,000m and from surface to more than 350m downdip.

Highlighting just how rich Andover could be, the lithium mineralisation remains open along strike and downdip.

Azure Minerals (ASX:AZS) certainly believes that there’s more to fine and has five rigs operating on the project to carry out both extensional and infill drilling along the AP0011 / AP0012 / AP0014 pegmatite corridor.

“It’s very pleasing to confirm that as we step out our broad-spaced drilling along strike and down-dip, we’re continuing to intersect substantial widths of high-grade lithium mineralisation,” managing director Tony Rovira said.

“The 50m to +100m mineralised widths confirm that the AP0011 / AP0012 pegmatite corridor, which extends over a strike length of more than 2km, has potential to host sizable volumes of lithium mineralisation.

“Our confidence that Andover has the potential to host lithium resources of world-class scale continues to grow, particularly as we consider the abundance of pegmatites within the overall project area that have demonstrated similar high-grade lithium mineralisation at surface that are yet to be drilled.” 

Andover pegmatites

The Andover pegmatite swarm extends over an area of 9km (east-west) and up to 5km (north-south) and comprises hundreds of outcropping pegmatites with many containing high lithium grades identified from extensive surface sampling.

Azure has to date completed 30 diamond holes totalling 9,790m and 25 reverse circulation holes totalling 4,889m to date.

Drilling is currently testing along the +2,000m strike extent of the corridor containing the AP0009, AP0010, AP0011, AP0012 and AP0014 pegmatites.

The company noted that the broad lithium intercepts in the latest holes ANDD0214 and ANDD0210 demonstrate strong continuity of mineralisation up-dip from the previously reported broad high-grade intersection in hole ANDD0208 of 105m at 1.26% Li2O.

Excellent lateral continuity of mineralisation has also been demonstrated in the central part of the AP0011 pegmatite with infill holes ANDD0216 (5.5m at 3.61% Li2O, 28m at 1.12% Li2O) and ANDD0217 (32.7m at 1.32% Li2O) confirm continuous mineralisation between the eastern intersections (ANDD0206 and ANDD0202) and the western intersection in ANDD0215.

Azure is currently awaiting assays from hole ANDD0223, which was drilled as a twin to hole ANDD0219 that intersected high-grade mineralisation of 4.9m at 1.92% Li2O at the top of the AP0011 pegmatite but was abandoned prematurely due to drilling issues.

Ongoing and upcoming work

Two diamond rigs and three RC rigs are currently testing the western extensions of AP0009, AP0010, AP0011 and AP0014 pegmatites with sequential step-outs on 200m-spaced sections over an 800m strike length.

Going forward, the company plans to carry out infill drilling on a 100m spaced sections to ensure rapid delineation of lithium resources.
