Cerro Grande Mining Corporation Reported Today that Watts, Griffis and McOuat has Completed an Updated NI 43-101 Technical Report on Pimenton Mine

TORONTO, July 28, 2016 /CNW/ - Cerro Grande Mining Corporation (the "Company" or "CEG") (CSE:CEG) (OTCQB:CEGMF)  reported today that Watts, Griffis and McOuat, Toronto, Canada has completed an updated NI 43-101 "Technical Report on the Pimenton Mine, the surrounding Pimenton Property, and nearby Tordillo Property in Central Chile". A "Summary of Resource Estimate 2016, Pimenton Mine" is as follows:

Summary of Resource Estimate 2016, Pimenton Mine
Category	Tonnes	Au, g/t	Cu, %
Measured	44,000	15.4	1.4
Indicated	36,000	10.0	1.1
Total Measured + Indicated	80,000	13.0	1.2
Inferred	14,000	9.7	1.0

"There is potential to expand the inferred resources considerably at this site as well as to find new veins. MMI Sampling has covered the alteration area surrounding the Pimenton Mine and outlined a gold geochemical anomaly 1,100 m by 600 m in extent. Coupled with satellite imagery, CEG has identified sixteen possible targets for trenching at surface or drilling from underground. A target of particular promise is at the western limit of a strong part of the MMI anomaly where strongly leached vein material had in the past reported 3.2 g Au/t over 2m. In WGM´s opinion, this exploration should be undertaken when funding is available ahead of any other exploration on the properties".

The recently discovered Monica vein has the potential to produce significantly higher grades. The Resource section of the WGM report states the following: "The low grades for the Monica stopes in Table 7 were obtained from muck pile samples derived from the lower portion of these stopes where dilution was increased by the uppermost flat-lying fault.  Sampling by CMP at the time of Brady's site visit of the current Monica 3195 stope back 20 m above the level yielded 13.9 g Au/t over 0.8 m (weighted average of 50 samples).  The grade of the Monica Vein is therefore expected by WGM to be higher than that used in our reserves and resources."

Pimenton Mine Mineral Reserves (Inclusive from the Resource Estimate) (Effective July 21, 2016)
Category	Tonnes	Au, g/t	Cu, %
Proven
Stopes	2,000	9.6	0.8
Remnants	28,000	15.8	1.4
Total Proven	30,000	15.4	1.4
Probable
Stopes	39,000	9.5	1.0
Remnants	0	0	0
Total Probable	39,000	9.5	1.0

The complete report has been filed on SEDAR.

The Company believes this report will be of assistance in helping it to raise a financing of US$3,000,000 to put its Pimenton Mine back into operation, which suspended operations on June 4, 2016 as previously reported.

Cerro Grande Mining Corporation is a minerals producing, exploration and development company with properties and activities currently focused in Chile.
