Executive Director, Matt Boyes, commented:

"We are delighted to announce the commencement of our maiden drilling program at Jaguar a mere 22 days after executing the option agreement over the project. The program is designed to provide our first indication of the potential strike, depth and thickness, along with confirmation of mineralisation style and grade. It's an extremely exciting time for the Company and its shareholders, as we drill at a previously underexplored pegmatite in what we hope will become Brazil's next major lithium province. I look forward to arriving on site as the first core is pulled from our maiden drill hole."

The initial program is designed to test the strike extent, thickness, orientation and the down dip extent of the pegmatite body along the known strike length of 1.4km. The first hole will target the down-dip extent of the main outcropping pegmatite in the Jaguar artisanal workings (Figures 2 & 4) with the hole position shown in Figure 3. This is expected to provide a better understanding of the structural controls and orientation of mineralisation and will be followed by step-out drill fences to define the continuity of the system (Figure 3).

The initial program is expected to take approximately 90 days during which the Company will keep shareholders informed at regular intervals with a series of updates as drilling progresses. All drill core will be processed at the Company's facilities nearby and sent to SGS laboratories in the State of Minas Gerais for assaying where current turnaround times are approximately 20-days from the submission date.
