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."
