Graycliff Exploration Intersects High-Grade Interval in Hole 21 of 19.38 g/t Gold over 4.20 Metres at Shakespeare Project, Ontario

Graycliff Exploration Limited (the "Company" or "Graycliff") (CSE:GRAY)(OTCQB:GRYCF)(FSE:GE0) is pleased to announce additional assay results from drilling on its Shakespeare Gold Project located on the prolific Canadian Shield near Sudbury, Ontario. The final results are from the 2,200-metre Phase Two program that focused on defining the extent of gold mineralization proximal to the historic Miller Shaft where initial gold mining took place more than 100 years ago

Drill Holes J-21-21 intersected a mineralized interval of 19.38 g/t gold ("Au") over 4.20 metres, including 13.10 g/t Au over 1.0 m and 112.00 g/t over 0.60 metres. Significant intervals for holes J-18-21 to J-21-21 are detailed below:

President and CEO James Macintosh stated: "Drill hole J-21-21, which showed significant visible gold in the drill core, returned another great result that was also one of our deeper mineralized intersections in the first two phases. This continues to support our theory that the deposit is open at depth and along strike. Results for the Phase Two drilling are now complete, and we are shifting our focus to Phase Three, which has been underway since earlier this summer. We have now successfully extended our mineralized zone to a width of over 115 metres."
