Infinitum Copper (INFI.V) has released the assay results from the first two holes drilled on the La Adelita flagship project in Mexico’s Sonora and Sinaloa states as part of the ongoing drill program. Holes 17 and 18 were drilled from the same drill pad, and as you can see below, hole 17 used a 45 degree azimuth while hole 18 went in steeper at a 67 degree angle.

Both holes did encounter copper mineralization but while hole 17 was nothing to write home about with 9.15 meters of 0.14% copper and 0.06 g/t gold, hole 18 was good. It was even exceptional. The drill bit encountered 24.35 meters (20.60 meters true width) of 1.91% copper, 2 g/t gold and just under 41 g/t silver, as you can see in the table below.

Even ‘just’ the 1.91% copper would have been a remarkable result but throwing in the gold and silver values using a price of $1725/oz and $18/oz respectively, the copper-equivalent grades of the two precious metals are 1.44% and 0.3% respectively (applying a copper price of $3.5/pound). This means the 20.6 meter interval actually carries a copper-equivalent grade of 3.65%. Encountering that type of grade over an interval of in excess of 20 meters on a true width basis is excellent.

The two holes were drilled just a few dozen meters away from the old Adelita adit to try to identify the extension of the high-grade copper-gold-silver mineralization at the Cerro Grande and Cerro Grande Footwall zone. And if we pull up the same cross section again, you see hole 17 had to be abandoned before reaching the desired depth.

And that’s a pity as the current interpretation of the mineralization encountered in hole 18 seems to focus on an upward trajectory and hole 17 appeared to have been lost just meters from the anticipated mineralization there and hopefully the company will follow up on this area in the Phase 2 drill program which should start after the end of the current rainy season in Sonora. An additional bonus is the high magnetite content encountered in hole 18 (with iron values averaging 24% Fe). The combination of semi-massive magnetite with high-grade Cu-Au-Ag mineralization should be detectable with detailed magnetometry and Infinitum Copper is planning to complete a detailed magnetometer survey after the vegetation in the area dies again.
