"In porphyry copper deposits, copper grades range from 0.2% to more than 1%, molybdenum grades range from approximately 0.005 to about 0.03%; and silver contents range from 0.004 to 0.35 g/t, gold content ranges from 0.2 to 5 g/t."

"Porphyry copper deposits are the largest source of ore, supplying nearly 60 percent of the world’s copper. Porphyry ore bodies typically contain between 0.4 and 1.0 percent copper in concert with smaller amounts of other metals such as molybdenum, silver and gold. Porphyry deposits are massive, and extracted by open pit mining."

I'm not sure if you've been following the drill program, if you were, you'd realize that the first 3 holes and the first part of the 4th have been focused on proving up the previously-estimated $2 billion mineralization in the Gordon Breccia...the ~400 meter pipe that leads down to the porphyry. Auryn Mining has drilled both in-fill drilling confirming the consistency of the mineralization and step-out drilling to expand the footprint of the mineralization (i.e. increase the $$$ estimate) while tracing the pipe down to the porphyry.
The drill program has not yet hit the porphyry of the deposit, though the fault line that was recently hit is where the presumed top of the porphyry begins. Stay tuned and read those articles I provided so you can better understand the implications of the drill results.
