Ongoing field reconnaissance of recent soil anomalies at Kalamazoo Resources’ (ASX: KZR) Marble Bar lithium project in Western Australia has discovered additional pegmatite outcrops and visible lithium mineralisation in the form of lepidolite (lithium mica).
Sample rock chip assays have returned up to 1.6% lithium oxide and 372 parts per million tantalum from lithium-mineralised dykes which trend into a newly-granted tenement within the neighbouring Dom’s Hill project to significantly extend the area of known mineralisation.
Kalamazoo chairman and chief executive officer Luke Reinehr said ongoing fieldwork at Marble Bar is delivering “excellent results”.
“We have identified multiple pegmatite dykes containing visible lithium mineralisation and strong rock chip assay results [and] these discoveries are lining up well with our pXRF (portable x-ray fluorescence) soil anomalies,” he said.
“We are pleased to see the pegmatite dykes extending into our newly granted tenement… we believe the potential for LCT (lithium-caesium-tantalum) pegmatite mineralisation in the immediate area is very high.”
The Marble Bar soil anomalies were identified in February and are believed to either contain, or sit in close proximity to, mapped outcropping lithium-bearing pegmatites.
The prospectivity of the region surrounding Kalamazoo’s assets is supported by Global Lithium Resources’ (ASX: GL1) nearby Archer deposit which sits within the Marble Bar lithium project and has a maiden inferred resource of 10.5 million tonnes grading 1% lithium oxide.
Global recently announced the start of a 60,000m reverse circulation drilling campaign at Archer, further highlighting the region’s lithium potential.
Soil geochemistry program
Kalamazoo recently completed a regional soil geochemistry program at Marble Bar and Dom’s Hill, which form part of its exploration joint venture with Chilean lithium producer Sociedad Química y Minera de Chile SA (SQM).
In December, SQM was granted the right to earn an initial 30% interest (up to a maximum 70%) in all mineral rights at the projects on sole funding a minimum $12 million of exploration and development activities over the next four years.
Kalamazoo’s nearby Pear Creek project covers 147sq km between Marble Bar and Dom’s Hill but is not included in the joint venture.
All three assets are considered highly prospective for pegmatite-hosted LCT mineralisation as well as gold.
Kalamazoo plans to commence an initial regional soil sampling program comprising approximately 2,300 samples across Pear Creek later this month.
