RAINMAKER - NEVADA LITHIUM - ABILITY TO ADVANCE TO PEA

Rainmaker recently announced a successful initial 43-101 technical report, which confirmed the high-grade lithium present at its Sarcobatus Flat project in Nevada. The report was completed on-budget and on-time.

The formal recommendation concluded that $2.4-Million USD would allow Rainmaker to advance through a 6-phase exploration including culminating in a PEA.

SARCOBATUS FLAT LITHIUM PROJECT, NEVADA

Rainmaker's Sarcobatus Flat high-grade lithium project is located approximately 70 km southeast of Clayton Valley - home to the only producing lithium mine in the United States. According to a recent U.S. Geological Survey, "Lithium supply security has become a top priority for technology companies in the United States and Asia." This area of Nevada has seen a rapid rise in exploration success. Access to the Sarcobatus Flat property is ideal as the project lies directly adjacent to a major US highway. Easy access to this flat and arid property means exploration costs are expected to be low and environmental impact will be minimal. The lithium content of soils and vegetation in the Sarcobatus Flat property, as reported by the Company (see Rainmaker release August 4, 2016) compare favourably with samples from Clayton Valley.

INVESTMENT HIGHLIGHTS

• Lithium: crucial mineral for electric car batteries and many other tech purposes
• Favourable Terms: share acquisition, cash reserved for exploration
• High-Potential Project: Company sampling of the near surface clays show lithium values of 140 - 300 ppm
• Location: mining-friendly Nevada
• Large Land Package: 234 placer mining claims totalling approximately 4,680 acres
• Infrastructure and Accessibility: adjacent to US Highway 95
• Rapid Advancement: lithium brines projects tend to require only a moderate amount of drilling to advance the property
• Low-Cost Exploration/Development/Production: the accessible nature of lithium brine deposits results in low costs overall
