The Filo del Sol property is comprised of mineral titles in both Chile and Argentina. Those in Argentina are controlled by Filo del Sol Exploración S.A. and are referred to as the Filo del Sol Property, those in Chile are controlled by Frontera Chile Limitada and are referred to as the Tamberías Property. Both Filo del Sol Exploración S.A. and Frontera Chile Limitada are wholly-owned subsidiaries of Filo Mining Corp.

Summary:
Mineralization in the Filo del Sol area shows affinities with both porphyry copper-gold-molybdenum and high-sulphidation gold-silver epithermal systems. The deposit defined by the mineral resource is best classified as epithermal in the north (Filo del Sol) and coppergold porphyry plus epithermal in the south (Tamberias). The mineralized system in its entirety is thought to represent a telescoped porphyry – epithermal system, with multiple intrusive and breccia centres, and so combines aspects of both these deposit types. The Flamenco fault is an important structure that separates the exposed porphyry Au-Cu system in the south at Cerro Vicuña - Tamberias, from the relatively down-dropped block to the north with the preserved high-sulphidation system at Filo del Sol.
The Filo del Sol deposit encompasses both the Filo del Sol high-sulphidation epithermal system and part of the Tamberias area which is interpreted as a fault-offset part of the same hydrothermal system. The deposit occurs within a porphyry Cu-Au and high-sulphidation epithermal Cu-Au-Ag system that formed during rapid uplift and erosion in the Middle Miocene. Porphyry intrusions and associated Cu-Au mineralization that are associated with an early, and largely eroded, epithermal system have been overprinted by at least one subsequent stage of porphyry intrusion and epithermal system development. The Filo del Sol system is largely associated with this second, later part of the progressive development of ........

Summary:
The Filo del Sol deposit is a large near surface, bulk mineable deposit that is well suited for extraction by conventional open pit methods. Ore and waste will be drilled, blasted and loaded by diesel hydraulic face shovels and front-end loaders from 12-meter benches. Haul trucks will haul the material to the ore crusher, a short-term stockpile, or the waste dump as required. Autonomous haulage was incorporated to take advantage of the technology’s proven productivity improvements and operating cost savings. The open pit will have a mine life of 14 years, including pre-stripping, with a life of mine strip ratio of 1.5:1. A maximum mining rate of approximately 65 Mt per year (including waste) is required to provide the nominal 60,000 tonnes per day of ore to the process facility. A total of 259 Mt of ore is expected to be processed over the life of the mine.
The pit design criteria used to develop the pit phase designs are as follows:
• All bench face angles are 65 degrees.
• Bench height is 12 m. All design sectors will use double benching including the Filo
LIX sector for which BGC recommends single benching.
• Haul ramps:
- 33.7-m wide double lane and 24 m wide single lane, based on the design 220mt capacity truck.
- No steeper than 10% on shortest ramp segment (inside corner) for uphill loaded hauls.
- For downhill loaded hauls, no steeper than 8%.
• Minimum Mining width 60m including one 7.2m outside be ........
