Zinc One Resources Inc. is a mineral exploration company focused on the development of its Bongará zinc mine project in Peru. The project has an indicated resource of over 800,000 tonnes averaging 18.9% zinc containing over 300 million pounds of zinc. Zinc One plans to advance the project through permitting, exploration drilling, metallurgical testing, and economic studies with the goal of starting production in 2021 using a simple on-site Waelz kiln processing facility. The company's management team has extensive experience exploring and developing mines in South America and globally.

are inherently uncertain and that actual performance may be affected by a number of material factors, many of which
are beyond their respective control. Such factors include, among other things: risks and uncertainties relating to metal
prices, changes in planned work resulting from weather, logical, technical or other factors, the possibility that results
of work will not fulfill expectations and realize the perceived potential of Zinc One’s mineral properties, uncertainties
involved in the interpretation of drilling results and other tests, the possibility that required permits may not be
obtained in a timely manner or at all, risk of accidents, equipment breakdowns or other unanticipated difficulties or
interruptions, the possibility of cost overruns or unanticipated expenses in work programs, the risk of environmental
contamination or damage resulting from the exploration operations, ability to obtain sufficient financing to
implement its exploration and development plans, Zinc One receiving favorable economic studies on its mineral
projects and development plans on Zinc One’s mineral properties and the need to comply with environmental and
governmental regulations. Accordingly, actual and future events, conditions and results may differ materially from the
estimates, beliefs, intentions and expectations expressed or implied in the forward looking information. Except as
required under applicable securities legislation, Zinc One undertakes no obligation to publicly update or revise

Zinc is currently the 4th most
widely consumed metal in the
world after iron, aluminum,
and copper and the 24th most
abundant element in the
Earth’s crust.

Advances in zinc battery technology
Zinc batteries have been used for decades.
Improved technology has led to longer-life and
steadier voltage output and the potential as a fuel
cell providing power to electric vehicles including
scooters, buses and trucks.
Advances in zinc for human health
Zinc deficiency takes a toll on humans and
agricultural productivity. It is the most common
micronutrient deficiency affecting >50% of
agricultural soils. Zinc fertilizer can significantly
increase crop yield, boost nutritional value and
improve farmers incomes.

The Zinc One Investment Thesis
4
A Path to Development
• Road to paved hwy, electrical grid and high water volumes NOT required
• Production targeted for 2021 - open pit operation with permitting on-track
• Waelz kiln processing on-site with minimal waste management (slag)
• Supportive local communities due to past tangible benefits of mining
Significant Exploration Upside
• High-grade zinc drill targets proximal to previously mined area
• 300 m x 400 m area between Mina Chica and Mina Grande Norte
• Campo Cielo (500 m north of Mina Chica)
• 8 km trend with known near-surface, high-grade zinc mineralization
