One World Lithium Drilling Update, Corporate Progress and Industry Trends

As previously reported, DDH-3 is located approximately 50 kilometers to the south of DDH-2 on the Company's Salar del Diablo property, located in the State of Baja California, Mexico. Mike Rosko, the Operator, from Montgomery & Associates expects DDH-3 and possibly DDH-4 will be more cost effective than previous holes drilled as aa more aggressive drill bit will be used and DDH 3 and 4 may only require total depths between 300 and 400 meters as DDH 1 and 2 reached an average total depth of 624 meters. Mike also noted the prospective area of possible hydrothermal activity may cover 20,000 hectares.

All samples will be assayed for drill holes DDH - 1 through 4 with the assay results released at the same time. On completing phase three of the drill program, OWL will have increased its working interest in the Salar del Diablo property from 60% to 80%. For more information on Salar del Diablo property and the terms of the Company's option thereon, please see the Company's press release dated March 10, 2017, and July 28, 2017.

In Mexico, mineral exploration has been deemed an essential service despite the country's various Covid-19 restrictions and, at present, the States of Baja California and Sonora currently have no further restrictions.

Lithium Separation Technologies

An ecosystem of junior mining companies are looking to take market share from major producers to meet the demand for high quality lithium chemicals and new resources to obtain these has become one of the most important emerging themes in lithium over the last five years.1 Accordingly, many of these new technologies can be developed and used in house by junior mining companies.

OWL has the right to purchase 100% of a lithium separation technology which is subject to a proof of concept testing. The Company hopes this may be successful within two months. The technology has the potential to separate lithium carbonate ("LCE") from a brine and, because of this, the Company perceives the technologies implementation as a potential industry game changer. Accordingly, some of the potential benefits may include not requiring evaporation ponds to separate LCE as well as returning the waste brine back to its producing brine formations that may stabilized the brine formation and extend a mine's life.

One World Lithium Trends

• - OWL's recent private placement offering was oversubscribed by 50% for proceeds of CAD $2,250,000.2

  - During the three month period ended December 31, 2020, OWL's secondary market traded 4.5 million common shares (each, a "Share") and in the first quarter ended March 31, 2021 it has traded 23.4 million Shares, for an increase of 421%.3

Lithium Industry Trends Are Impressive

• - The seaborne LCE battery grade spot price has increased from USD$6,000 to USD$7,500 per tonne on October 23, 2020 to USD$9,500 to USD$11,000 per tonne on March 19, 2021 (trading between China, South Korea, and Japan).4

• - Since January 1, 2021, Bloomberg reported a total of US$3.4 billion raised in equity financings in the North and South America which is seven times the total amount raised from 2018 to 2020. 5

  - Since January 1, 2021 to March 18, 2021, Bloomberg reports that junior lithium companies have raised an aggregate of USD$529 million from the capital markets. That is about USD$63 million more than the total amount raised from 2018 to 2020.5

  - The demand for lithium for electrical vehicles ("EVs") is expected to in increase approximately 599% by 2025.6

Given the renewed investor interest in the lithium sector which is driven by significant increases in the price of lithium carbonate equivalent (LCE), it has impacted OWL as its previous private placement was oversubscribed by 50% or $750,000 and its secondary market trading volume also increased over 421% to 23.4 million shares from the three month period ended December 31, 2020 compared to the three month period ended March 31, 2021. This is in response to the increase in demand for lithium-ion batteries.
