On August 12, 2020 Liberty Gold closed the sale of its interest in the Halilaga porphyry copper-gold deposit to Cengiz Holdings A.S. (“Cengiz”) pursuant to a definitive agreement signed on July 12, 2019 (the “Halilaga Agreement’). Liberty Gold interest in Halilaga was held through a 40% shareholding in Truva Bakir Maden Isletmeleri A.S. ("Truva Bakir"). TMST held the remaining 60% of this Turkish entity. Pursuant to the terms of the Halilaga Agreement, the Company and TMST agreed to jointly sell their 100% interest in Truva Bakir to Cengiz for $55 million cash. As a result of the Transaction, Liberty Gold will receive a total of US$22 million.

Summary:
Halilaga is classified as a copper-gold porphyry system. Advanced argillic alteration and gold mineralization at Kunk Hill and Pirentepe are classified as high sulphidation epithermal mineralization. Copper mineralization in the Bakirlik Tepe area is classified as proximal copper skarn. All three types are related to magmatic-hydrothermal activity associated with intrusion of the Kestane porphyry stock and other intrusions in the area.
The geology of Halilaga is characterized by various lithological associations made up of: (1) Paleozoic and early Mesozoic basement metamorphic rocks; (2) Permian and Mesozoic sedimentary and ophiolitic rocks; (3) Tertiary volcanic and intrusive rocks; and (4) Neogene sedimentary rocks. Older rocks are affected by several collisional orogenic events. Tertiary rocks record mainly brittle extensional and transtensional deformation.
The property is located in a district with significant potential for both porphyry copper-gold and high-sulphidation-style gold deposits. Investigation of geological relationships in the field along with geochemical and geochronological data suggest that magmatic activity began with the intrusion of granitoids, coeval with an early phase of volcanic activity, and was superseded by a second phase of volcanism. The mineralized intrusives are thought to be part of a suite of 26 to 38 million year old (Ma) quartz monzonites and granodiorites.
The Halilaga district is mainly underlain by Ol ........
Summary:
250 mm diameter blast hole drills are planned to perform the bulk of the production drilling in the mine (both mineralized and waste rock). The hydraulic drill with a 115 mm diameter bit would be used for secondary blasting requirements and may be used on the tighter spaced patterns required for pit development blasts. The main loading and haulage fleet is planned to consist of 40 t haul trucks, loaded primarily with the diesel powered 7 m3 front shovels or the 7 m3 wheel loader, depending on pit conditions.
As pit conditions dictate, the D9-class dozers are planned to rip and push material to the excavators and maintaining the waste dump.
The additional equipment is planned to be used to maintain and build access roads and to meet various site facility requirements, including stockpile maintenance and further exploration development.
