SnapshotThe Leliyn Project is Australia’s largest graphite deposit. The resource was defined from just 4km of a 20km outcropping graphitic schist unit, highlighting substantial potential for future expansion.

The mineral resources is near surface and amenable to very efficient and productive open pit mining techniques with a very low strip ratio.

In addition to graphite, Kingsland is advancing the potential of the Leliyn Graphite Project in the Northern Territory, with metallurgical test work now underway to assess the recovery of two high value by-products: gallium and rutile.

Ongoing drilling and an increase in Indicated Resources are expected to support the development of a long-life, economically robust graphite concentrate operation.

Summary:

The graphitic schist is relatively homogeneous with hard boundaries between the graphitic schist and surrounding barren material.

The Leliyn Graphite deposit is focussed along the contact between the Cullen Granite and the Mundogie Formation. Carbon rich sediments within the Mundogie Formation have been contact metamorphosed by the intruding Cullen Granite. The carbon within the sediments has been converted into graphite. Graphitic schist is generally found adjacent to or within <100m of the granite contact. Hornfelsed sediments of low carbon content are also found adjacent to and sometimes within the graphitic schist. The graphitic schist occurs as a sub-vertical zone of about 100m horizontal width. The horizontal width can vary within the western part of the MRE from 50m to 150m horizontal width, with a minor fault offset interpreted in the area of infill drilling. Towards the east of the MRE area, the graphitic schist is interpreted to have been structurally deformed by folding and faulting. This has resulted in a series of dis-jointed zones of graphitic schist with two smaller zones of graphite mineralisation modelled with widths varying between 15 and 120 m. This occurs where the Mundogie Formation forms an embayment into the Cullen Granite.

The MRE is interpreted to form three separate mineralisation zones based on a nominal 3% TGC lower cut-off primarily falling within the material recognised and logged as graphitic schist by Kingsland geologists in the drill sampling, and with reference to the surface geological mapping and geophysical fixed loop electromagnetic (FLEM) data modelling. The mineralisation widths are interpreted using a nominal minimum of 4 metres down hole above the cut off, with internal waste zones based on a minimum of 4 metres below cut-off allowed. A total of thirteen internal waste zones have been modelled overall. A cross cutting shear zone and one fault causing minor offsetting in the main western mineralisation zone have also been interpreted. The near surface weathered material is on average roughly 20 m vertical depth and the topographic surface has been dropped 20 m to represent the top of fresh rock surface.

The mineralisation in the east is somewhat disjointed due to more intense folding and faulting with two zones interpreted. The smallest eastern most zone has a strike extent of roughly 340 m, width of ranging from 20 to 40 m and a depth of around 170 m below surface. The second of the eastern zones has a strike of roughly 670 m and ranges in width between about 15 and 120 m with a depth extent between 170 and 190 m below surface. These two zones have been extrapolated along strike by 50 m. The western lens is not as affected by structural influences and is interpreted to form a continuous arc of mineralisation with a strike extent of roughly 3 km. the width varies between about 50 and 150 m and the classified depth extent is between roughly 150 to 400 m below surface which is nominally 50 m below the drilled mineralisation intersections. This zone has been extrapolated by 200 m along strike with reference to the surface mapping drill section spacing. There is an area of about 1,200m length between the western mineralised zone and the two eastern mineralised zones where there is no drilling. This area is considered likely to host additional graphite mineralisation based on surface mapping data.
