| Area: | 3 concessions approximately 5,875 Hectares |

| Status: | First phase scout drilling, some past artisanal mining, developing drill targets |
| Ownership: | 100% (subject to 1% NSR) |
History:
Selective artisanal mining on the property was being carried out as recently as the late 1970's. There are at least 5 different areas on the property where artisanal mining occurred. Previous historical mining occurrences have indications that high grade gold is present on the property. Mining was done from surface cuts, shallow stopes and small declines/tunnels, which vary from 5 to 50 metres in length. Chesapeake Gold geologists explored the property beginning in 2006 with a strong focus in one area of mineralization referred to as the "The Main Zone". Other regional sampling was completed within 3 km of the Main Zone with anomalous results.
Property Geology:
The geology of the Tecomate project is not yet well understood, but it is known that precious metals of economic interest mainly occur in a northwest-trending corridor that is roughly 1.5 km wide. That corridor is interpreted to be the margin of a caldera or superimposed calderas. Paleocene tuffs, subvolcanics, and agglomerates collectively known as "Lower Volcanics" comprise the geology of the corridor and they are predominantly andesitic. Elsewhere in the Western Sierra Madre the Lower Volcanics host virtually all known gold deposits. Unaltered Oligocene "Upper Volcanics" unconformably overly the Lower Volcanics and bound the main corridor of gold mineralization at Tecomate on the northeast and southwest. The Upper Volcanics are thought to have been down-dropped during caldera collapse, and are predominantly rhyolitic tuffs and agglomerates in the lower part of the package and ignimbrites in the upper part of the package.
Mineralization:
Mineral systems identified so far at Tecomate occur within a primary structural corridor approximately 1.5 km wide and at least 4 km long. This corridor is interpreted to be the margin of a caldera or superimposed collapsed calderas. Numerous artisanal workings occur within this area and were focused on northwest trending shear veins, sheeted veinlet zones and breccias. These occur within zones of phyllic altered volcanics up to 200 meters wide. A secondary corridor as been outlined 2 km east from the primary corridor, with similar mineralization styles. This area is currently 250 meters wide and approximately 1 km long. Currently four mineralized zones have been identified at Tecomate: Northwest, Main, Southeast, and Brenda.
