Graycliff Exploration Continues Intercepting Near Surface Gold Mineralization with Hole 10 Grading 5.51 g/t Gold over 4.0 metres

Graycliff Exploration Limited (the "Company" or "Graycliff") (CSE:GRAY)(OTCQB:GRYCF)(FSE:GE0) is pleased to announce additional assay results from its over 2,000 metre ("m") phase two core drilling program on the Company's Shakespeare Gold Project located on the prolific Canadian Shield near Sudbury, Ontario

Drill Hole J-10-21 intersected two mineralized intervals eight metres ("m") apart with the higher interval returning 5.51 g/t gold ("Au") over 4.0 m, including 24.60 g/t Au over 0.55 m. Drill Holes J-11-21 and J-14-21 were stopped after of 30 m as they intercepted the historic underground workings or a fault. Drill Holes J-12-21 and J-13-21 were heavily fractured and core recoveries were poor. The significant intervals for Holes J-10-21 through J-14-21 are detailed below:

President and CEO, James Macintosh stated: "The continued success we are having at Shakespeare is very encouraging. We now have anomalous gold intervals in 9 out 14 holes and we are getting some very significant widths and grades in several of those holes. As we have mentioned before, we continue to see visible gold in some of the drill core and we look forward to receiving those results in the coming weeks. All of this information will be going into the 3D model that we have commissioned. I strongly believe that at current prices, Graycliff is fundamentally undervalued considering the continuing success of our ongoing drill program"
