Ken Lapierre, President & CEO of Rockcliff commented; “This transformational transaction is finally

complete and we can now position Rockcliff as a leading base metals developer and explorer in one of

the most established mining jurisdictions in the world. Rockcliff is now very well funded as a result of a

cornerstone investment from Greenstone and has secured two advanced stage copper assets and a

leased processing facility from Norvista. Our 100% owned Tower copper project is anticipated to be fully

permitted by Q4 of this year which will allow us to make a construction decision as early as Q1 of 2020.

Over the next two years we will implement one of the largest copper-zinc focused exploration programs

undertaken anywhere in the world by a junior resource company. It will include almost 100,000 metres

of drilling and will provide substantial news flow to the market. This drill program gives us the potential

to significantly increase our existing resources as we search for the next big discovery in this world class

mining belt. We thank our shareholders for their overwhelming support and patience during this long

and detailed process. We look forward to unlocking the full value of our high-grade Manitoba assets

and transitioning Rockcliff into the next major base metal producer in the Flin Flon-Snow Lake

greenstone belt.”
