Millennial Commissions Renewable Energy-Powered On-Site Development Park at Their Flagship Pastos Grandes Lithium Project; Caution Regarding Recent Online Article Concerning the Company

Vancouver, British Columbia--(Newsfile Corp. - March 4, 2019) - Millennial Lithium Corp. (TSXV: ML) ("Millennial" or the "Company") is pleased to announce the inauguration of its on-site permanent Project Center, including a 60-100 person camp, an on site laboratory, and a process pilot plant under construction which is to be commissioned in the second quarter. In line with the Company's commitment to sustainability, the Project Center is to be powered by a state-of-the-art hybrid solar power system that will reduce CO2 output and costs for fuel.

Millennial President and CEO, Farhad Abasov, commented: "We at Millennial are excited to be on the leading edge of the green revolution in commissioning our renewables-powered project development park at our Pastos Grandes Salar lithium brine project in Argentina. This follows through on our personal commitment to the environment while preserving shareholder value, and our goal of producing lithium products with a low CO2 footprint. The hybrid solar power system for the Project Center is the first of its type in the Puna region of Northern Argentina. In addition to its primary benefits of minimizing CO2 output while significantly reducing operating costs, the camp energy system will help us to quantify and maximize the benefit of renewable energy saturation in our commercial operations engineering and commissioning."

The Puna region of Northern Argentina has one of the highest levels of solar loading in the world, making it very attractive for sustainable technologies that minimize emissions of greenhouse gases. During the design and engineering phase of the Project Center, Millennial solicited proposals for renewable energy systems. Argentina and the province of Salta have implemented regulations and incentives to promote the adoption and use of renewable energy, thus there were a number of highly qualified providers. After careful consideration of a number of excellent proposals, Millennial selected an experienced local Salta company, Ergy Solar, to install and commission an integrated solar photovoltaic, battery and backup conventional power generation system. Utilizing 540 (1,050 square meters) photovoltaic (PV) panels of 330 Wp each totaling 178.2 KWp of solar power, a 500 kwh maximum storage bank of batteries and two low emissions diesel generators. The hybrid solar system is managed by a "smart" central controller that constantly reads loads and optimizes power output to the Project Center and the batteries to take full advantage of the high levels of solar resources in the Puna region. The system always prioritizes sustainable energy over traditional fossil fuels, resulting in major savings. The PV panel and battery system can provide power at maximum capacity for more than 18 hours throughout the daily 24-hour cycle, with diesel generator back-up only for some peak energy consumption times and infrequent non-sun events. At nominal energy use levels, the system will reduce fuel consumption costs by more than US$250,000 per year, and CO2 output by 147 tonnes annually.

The, turn-key, modern energy system has been completely engineered and built by Ergy Solar on-schedule, using the latest technology from tier-one manufacturers, including GCL solar panels, Hoppecke batteries, SMA inverters, chargers and control systems incorporating ABB components, and low-fuel-consumption Cummings 100 and 132kVA diesel generators. Final warranty inspection by ABB and commissioning will be completed by March 7. Photographs of the solar installation and camp are available for viewing on the Millennial Lithium website www.millenniallithium.com

The permanent camp, designed to house between 60-100 personnel includes comfortable dormitory units with private rooms and bathrooms, a full kitchen, dining room, recreation center, site offices and infirmary.

An on-site laboratory has been installed and is being commissioned. The lab, featuring an Agilent Technologies model 5110 2-axis ICP-OES analyzer will allow for quick turnaround of analyses for the ongoing pilot ponds system and the pilot plant.

The pilot plant has been designed for a 3 tonne per month output of battery quality lithium carbonate. The plant will be commissioned in the second quarter, and in the third quarter is anticipated to be producing battery quality lithium carbonate for optimization testing and customer trials.
