Rain City Resources Inc. (CSE: RAIN) Announces MOU with Advanced Mining

Technology Center of University of Chile

Partnership to focus on direct-lithium-extraction technology (DLE)

Wednesday, October 23, 2024 – Vancouver, BC – Rain City Resources Inc. (RAIN:CSE) (the

“Company” or “RAIN”) announces it has entered into a Memorandum of Understanding (“MOU”)

with the Advanced Mining Technology Center (AMTC) of the University of Chile. AMTC is the

leading research center in Chile in technology applied to mining, whose mission is to generate world

class multidisciplinary research and transfer new technologies in response to the challenges of mining

in Chile.

Chile ranks as the second- largest lithium producer in the world accounting for about 24% of global

production. Partnering with AMTC allows Rain to collaborate with some of the nation’s top talent and

expertise. The objective of this collaboration is to promote the advancement of environmentally

responsible extraction of lithium and associated by-products from salars in Chile.

The partnership between Rain and AMTC will focus on strategic areas of DLE including:

a) collaboration on opportunities in joint Research and Development (R&D) projects;

b) evaluation of defined projects and processes;

c) support in process certification through technical studies and access to AMTC laboratories and

technicians for analysis of samples taken from Rain’s Chilean projects;

Benjamin Hill, CEO of Rain commented:

“It is a tremendous privilege to collaborate with AMTC and the University of Chile. This MOU aligns

perfectly with Rain’s objectives to position the ACCELi technology as one of the most environmentally

friendly and lowest cost lithium extraction methods globally. We also welcome the opportunity to

bridge relationships between Canada and Chile in the DLE sector and look forward to a cooperative

and productive relationship.”

About AMCT

AMCT was founded in 2009 in the Faculty of Physical Sciences and Mathematics at the University of

Chile and supports more than 170 researchers including academics and graduate students. In addition

to partnerships with private sector mining exploration and production companies, AMTC has also

developed significant cooperation agreements and joint research initiatives with government agencies,

and research and technology centres worldwide. In 2021, AMTC executed a technological development

agreement with Codelco, Chile’s state-owned mining company, with a mandate to drive innovation and

address environmental challenges in the mining sector.

About Us:

Rain City is an integrated lithium technology and project development company committed to solving

the environmental, social, and economic issues associated with extracting lithium from brine. Adapting

technology which has already been proven in the oil fields with over 20 million barrels of water treated,

to one of DLE, will, we believe, provide a step-change in the cost of lithium production, with an industry

leading footprint and with little to no water use.
