Benson Project Background

Metalero has signed a binding Letter of Intent (“LOI”) to acquire 100% of the Benson Project

which is strategically located in the Quesnel Trough, one of Canada’s most important

mineral belts. The Quesnel Trough is a Triassic/Jurassic-age belt of volcano-sedimentary and

intrusive rocks which hosts >360 alkalic copper-gold porphyry occurrences and deposits. At

>1,500 km long, the Quesnel Trough runs through the middle of BC stretching from the US to

the Yukon Territory. It hosts numerous major mines which produce copper and gold as well

as variable amounts of silver and molybdenum while also hosting several type s of gold

deposits.

High profile and long-lived mines in the Quesnel Trough include Highland Valley, Mt Milligan,

New Afton and Kemess which are complemented by recent exploration work including

Woodjam, MPD, Kwanika, and the extensive staking by Australian mining giant, the

Fortescue Group.

The Benson Project lies close to infrastructure and is traversed by Highway 26 and a vast

network of logging roads allowing for ready access to all parts of the Property and capital -

efficient exploration. The large land package covers 5 different target areas i lluminated by

recent Artificial-Intelligence (“AI”) w ork b y Geoscience BC (Mitchinson et al., Geoscience

BC Report 2022-07). This AI study incorporated a wide variety of historical datasets including

geophysics, geology, sampling information, and drilling data (where present) to identify high

potential (“porphyry -like”) anomalies with similarities to known porphyry deposits

elsewhere in the belt. Even the l imited historical exploration at Benson has identified

numerous gold and copper surface geochemical anomalies while modest , historical drill

programs have intersected skarn and epithermal gold and silver mineralization, which are

both intrusive-related styles of mineralization and are commonly associated with porphyry

systems.
