Rock Tech Lithium Inc. 100 % Indirect
Claims for the mining rights are owned 100% by Rock Tech either directly or through its wholly-owned subsidiary James Bay Midarctic Developments (“JBMD”). For the Nama Creek leases Rock Tech holds the surface rights. The surface of all the other areas belong to the Crown. Rock Tech has legal access to its claims. The due dates for the claims range from May 2021 until August 2025 and for leases until Jan. 2031 or Jan. 2033

Deposit Type

  • Pegmatite
  • Metamorphic hosted


Summary:

Lithium occurs as spodumene in pegmatites in the Georgia Lake area. The pegmatites are hosted by metasediments. All pegmatites are Albite-spodumene type. Spodumene is the dominant Lithium (“Li”) bearing mineral in the pegmatites. Overall, the pegmatite dyke internal zonation increases in complexity from north to south within the Georgia Lake pegmatite field:
- Nama Creek - MZN and MZSW have simple zonation: aplite or granitic border zone and a spodumene zone with minor alternating aplite + pegmatite layers; and
- Harricana, Line 60 and Conway have aplite or granitic border zone, a spodumene zone and common alternating aplite + pegmatite layers.
The mineralization in the Georgia Lake Lithium Property consists of coarse-grained fresh pale green spodumene crystals, oriented perpendicular to the strike of the pegmatite dyke in homogeneous dykes, and randomly oriented within the inner spodumene zone in simply zoned pegmatite dykes. The spodumene may be altered to muscovite or fine-grained muscovite near the contacts with the host rocks and near diabase dykes. The altered spodumene has low Li contents and a high iron content.

The geology of the Georgia Lake area is of Precambrian age and is discussed by Pye (1965). The local rocks were build-up from the following types: metasediments, metagabbro, granite, pegmatite, sedimentary rocks, diabase.

Most of the pegmatites in the Postagoni Lake group and Georgia Lake group can be classified as albitesp ........


Mining Methods

  • Truck & Shovel / Loader
  • Cut & Fill
  • Sub-level stoping
  • Backfill


Summary:

The most suitable mining strategy for the Georgia Lake Project is a combination of surface and underground methods. In general, underground access can be developed from surface or from the pit bottom of the open pit with reduced incline length for mineralized body access, cost and development time. The access to the MZN mineralized body has to be developed while the open pit is still in operation and therefore a separate access has been chosen. For the other 3 small deposits access from the pit bottom has been chosen.

Open pit strategy
For outcropping and near-surface pegmatite sections, standard open pit methodologies will be employed. The rock will require drilling and blasting, and then trucked to the processing plant, the waste dump (material below cut-off grade) or at some point as backfill underground. The preliminary mining sequence foresees the extraction of MZN followed by HAR, L60 and Conway. MZSW will be mined by underground method only. During extraction of the MZN pit, waste material will be dumped nearby at the surface on a waste dump. Once this pit is fully excavated, waste material from other pits can be dumped inside MZN. Intermediate waste dumps on surface might locally be required.

Based on the optimized ultimate pit envelope, four open pits were designed for MZN, HAR, L60, and CON (MZSW mined by underground method only). Preliminary design parameter based on rock mechanical properties.
