The Wolfsberg Project will comprise two integrated operations, a mining and processing operation to produce a lithium concentrate (spodumene), and a hydrometallurgical plant to convert the spodumene into battery grade lithium hydroxide monohydrate (LHM).
On 15 August 2023, the Company announced it had received a grant of new mining licenses and extensions for the Wolfsberg Lithium Project located in a new mining field called Barbara. The grant of new licenses and extensions grows the Company’s Wolfsberg Project to a total of 20 licenses, nearly doubling the footprint for the underground mining operations. |

The Wolfsberg Project is held through European Lithium AT GmbH, a 100% owned subsidiary of European Lithium.
In October 2022, European Lithium AT (Investments) Limited signed a definitive merger agreement with publicly traded special purpose acquisition company Sizzle Acquisition Corp.
The combination will form a lithium mining company called Critical Metals Corp., which will own the Wolfsberg Lithium Project.
On March 1, 2024 - European Lithium Limited (the Company) announced completion of the business combination between the Company and Sizzle Acquisition Corp., to form Critical Metals Corp. Critical Metals commenced trading on the Nasdaq on 28 February 2024 under the symbol CRML.
European Lithium Ltd. holds 67,788,383 ordinary shares in Critical Metals and is the largest stockholder with 83.03% of issued capital.

Summary:
The spodumene bearing pegmatites occur in form of veins within a regional anticline. The pegmatite veins are intruded into amphibolite and mica schist host rocks strictly concordant to their foliation. On the northern limb of this anticline, which is known as Zone 1, the strata uniformly strikes WNW-ESE(average 120 º) and dips to the NNE at an average of 60 º.
The amphibolite hosted pegmatites (AHP) are stratigraphical hanging wall position relative to the mica schist hosted pegmatites (MHP) although they overlap. The AHP has greyish to greenish spodumene crystals aligned sub-parallel to the pegmatite contacts and average about 2 to 3 cm in length reaching a maximum of 15 cm. Spodumene crystals are more or less homogeneously distributed within a fine-grained matrix of feldspar and quartz with flakes of muscovite. The MHP lack the typical features and textures of pegmatites having undergone a penetrative metamorphic overprint almost completely recrystallising the original pegmatitic minerals. The spodumene minerals are in the form of mm sized lenticular grains embedded into very fine feldspar, quartz and muscovite matrix.
MINERALISATION
The Project is located within the Koralpe-Wölz nappe system of the Upper Austroalpine unit of the Eastern Alps, a mountain range composed of pre-alpine (mainly Palaeozoic) medium- to fine-grade metasedimentary rocks. Within the Eastern Alps, a pegmatite belt covers an area of over 400 km, where most of the pegmatit ........
Mining Methods
- Longhole open stoping
- Sub-level stoping
- Longitudinal open stoping
- Cemented paste backfill
- Unconsolidated rockfill
Summary:
The most appropriate underground mining method is a variant of sublevel stoping, longhole open stoping (LHOS) with paste fill. The neighbouring stopes are mined in succession, always alongside a cemented, backfilled stope.
European Lithium plans to operate the Wolfsberg underground lithium mine with BEVs, which will contribute towards a low carbon footprint production of lithium hydroxide, and will also reduce the ventilation requirements over the LOM. Due to the project footprint constraints at the mine portal and concentrator plant site, the surface infrastructure is to be kept to a minimum. No permanent waste storage facilities are to be constructed, and part of the plant infrastructure (ore sorter plant) is to be housed in specifically designed underground caverns, alongside the paste backfill plant.
The Wolfsberg Project requires significant upfront underground development to create the various caverns, silos, and waste stopes, and to provide access and sufficient working areas to achieve a sustainable sorter plant production rate of 45 kt/month.
Two main lithologies are to be mined, amphibolite and mica schist, with some minor mica gneiss recovered during the initial development works. The mica gneiss is to be used in the concentrator plant terrace construction. European Lithium plans to sell all the amphibolite as aggregate. All the material streams that are not considered saleable are to be stored underground as uncemented rockfill (mi ........
