Osisko Metals was recently issued with a new Land Use Permit and new Water Licence for the Confirmation and Exploration Program at the Pine Point Project site. The new permits were granted in late July 2022 and replaced previous permits. The proposed Pine Point Project would be comprised of 55 mining sites (47 open pits and 8 underground deposits) and one central concentrator plant site. |

On April 6, 2023, Osisko Metals Incorporated announced the successful closing of its previously-announced joint venture transaction with a subsidiary of Appian Natural Resources Fund III LP, which resulted in the formation of a joint venture for the advancement of Osisko Metals' Pine Point Project. Osisko Metals and Appian now hold approximately 74.7% and 25.3%, respectively, of the share capital of Pine Point Mining Limited (which holds a 100% interest in the Pine Point Project).
Appian will provide 100% of the equity funding required for the project until it has acquired an ownership interest of 60% in PPML or until a Final Investment Decision has been reached. The parties will fund any additional equity capital requirements for the project pro rata.
On February 22, 2024, Osisko Metals Incorporated sold an additional 5% ownership interest in Pine Point Mining Limited to a subsidiary of Appian Natural Resources Fund III LP, a fund advised by Appian Capital Advisory LLP.

Summary:
The Pine Point deposits are carbonate-hosted lead-zinc sulphide deposits with aspects of Mississippi Valley-Type (“MVT”). MVT deposits and a broader class of deposits called “sediment-hosted Pb-Zn” deposits (Leach et al., 2010).
Mineralization is hosted in three distinct deposit types:
1. Prismatic Deposits–Prismatic deposits demonstrate considerable vertical continuity but with limited lateral extent and are discordant. Mineralization is coarse to medium grained. These deposit types are further divided in to normal and abnormal prismatic deposits based on their relative stratigraphic position in the sequence. They contributed greatly to the Pine Point historical production as they contained very high-grade base metal grades and thicknesses.
2. Tabular Deposits–Laterally continuous, semi-concordant mineralized zones mostly restricted to a specific carbonate horizon.
3. N204 Deposit–N204 mineralization consists of fine crystalline mineralization deposited within the porosity ofstrati-bound layersbelow the mainsequence known as the B-spongy horizon where intense dissolution resulted in the development of a fine dolomite breccia. This type of deposit has to date only been identified at N204.
Prismatic Deposits
Prismatic deposits are generally high-grade and can contain up to 50% combined Pb-Zn, depending on the amount of sulphide mineralization present. These deposits are vertically continuous for up to 60m, and later ........

Summary:
The Pine Point Lead-Zinc Project is composed of numerous lead-zinc deposits that cover a 65-km strike length.
The Project is to be mined both as open-pits and underground workings. Two types of geological deposits (Tabular and Prismatic) are included in the mineralized material. The Tabular deposits are a rather flat layer, at shallow depth (less than 200 m) and are generally thin (5-10 m). The Prismatic deposits have a more vertical extent that could have up to 60 m thickness and are still shallow. The shape of these two types of deposits creates a series of aligned pit shells or underground workings that have generally less than 1,000 m in diameter. Some of the deposits are extensions of pits from the Cominco era that were not known or not economical at the time, while others are new discoveries.
Most of the deposits are planned to be mined as open-pits and are located in the northern and main trend. The deeper deposits with higher strip ratio are planned to be mined from underground, when the grade can support such mining method operating costs. The total mineralized material is 37.9 Mt grading 3.98% Zn and 1.44% Pb for open-pits, and 9.0 Mt grading 6.14% Zn and 3.11% Pb for underground. The total combined mineralized material is 46.9 Mt at 4.39% Zn and 1.76% Pb.
Forty-seven deposits from four zones (East Mill, Central, North, and N204) are mined as open- pits, considering the deposit’s size, shape, orientation, and proximity to the surfac ........

Reserves at July 11, 2022:
The estimate is reported using a ZnEq cut-off varying from 1.25% to 1.50% for open-pit mineral resources and 4.15% to 4.50% for underground mineral resources.
