Little-known Oceanus makes its mark in Mexico

Oceanus Resources (TSXV: OCN) is finding high grade gold and silver mineralization over significant widths on its 100%-owned Lajita property in the central portion of the Sierra Madre Occidental Province of Mexico.



Oceanus Resources (TSXV: OCN) is finding high grade gold and silver mineralization over significant widths on its 100%-owned Lajita property in the central portion of the Sierra Madre Occidental Province of Mexico.

The most significant mineralization on the property, which sits in the southwestern corner of the state of Durango, near its borders with Sinaloa and Nayarit states, has been found in seven zones so far: La Fortuna, Esperanza, Santo Nino, Dos Hermanos, Mina la Guadalupe, Las Ratones and Cerro del Sol.

The property is underlain by volcanic sequences and intrusive rocks disrupted by faulting, and the mineralization is found in a number of locations along the northwest trending La Lajita and La Lajita East structures. The mineralization consists of epithermal low-sulphidation quartz-adularia vein systems with breccias and stockwork carrying gold and silver along and adjacent to the La Lajita fault.

In September Oceanus reported results from diamond drilling at both the Santo Nino and Dos Hermanos prospects that included intersections of 7.1 g/t Au and 48.8 g/t Ag over 20 metres, including 18.9 g/t Au and 71.3 g/t Ag over 6.5 metres, at Santo Nino, and 10.2 g/t Au and 143 g/t Ag over 1.7 metres at Dos Hermanos.

The tightly held junior has a market capitalization of just $9 million, with a total of 36 million shares that over the last year have traded in a range of 15¢ to 30¢. At press time Oceanus was trading at 25¢ per share.

“There are not many opportunities to buy into an extremely attractive exploration play once the first round of excellent core drill results have been announced,” Tony Hayes, an independent mining analyst that follows the company, wrote in a recent email to The Northern Miner. “It outcrops at surface as a brecciated fault zone that has been traced over 2 km.”

“The market just seems to be totally unaware of this story,” adds Hayes, a chartered financial analyst. “This is where money can be made – going from having nothing to having something – and the early indications are that Oceanus could have something big.”

The drill results released in September followed channel sampling and geological mapping work at the La Fortuna and Cerro del Sol zones. The most significant results of that work included 8.53 g/t Au and 31.7 g/t Ag over a length of 12 metres from channel sampling at La Fortuna and 2.03 g/t Au and 11.3 g/t Ag over 16 metres, including 4 metres of 4.71 g/t Au and 23.5 g/t Ag in channel sampling at Cerro del Sol.

In June, initial results from underground and surface channel samples collected within the Santo Nino zone included 10.64 g/t Au and 41 g/t Ag over 10 metres (from underground sampling) and 3.46 g/t Au and 42.3 g/t Ag over 16 metres (from surface sampling). The Santo Nino zone is about 600 metres along strike to the north of the Dos Hermanos zone and is situated on the same fault system.

Underground and surface samples collected at the Mina la Guadalupe zone, meanwhile, which were reported in May, returned 13.7 g/t Au and 71.5 g/t Ag over 8 metres (from underground) and 11 g/t Au and 65.1 g/t Ag over 13.5 metres (underground).

The earliest small scale mining by pick and shovel on the property dates back about 50 years, and the most significant mining took place at La Guadalupe, where underground workings followed the mineralization along strike for 150 metres.

Hayes notes that while still at an early stage, the discovery is being compared to the early stages of the discovery of Pinos Altos, which “had a similar breccia fault hosted gold and silver mineralization in the upper volcanic sequence of that deposit before Agnico Eagle acquired it and drilled the lower volcanic sequence to discover the major part of the mine.”
