Cooke Mountain Project


Oversight - Lambert Creek – HLK - Lamefoot South - Lamefoot East – Goodfoot – Strongfoot - St. Peters Creek

Adamera Minerals holds a broad land position in the Cooke Mountain area in Washington State. The land surrounds or encompasses part of 5 past producing mines including Overlook, Lamefoot, Key West, Key East and Belcher. The Kettle River Gold Mill which was recently placed on care and maintenance is central to Adameras Cooke Mountain project. Approximately 1M oz. of gold have been mined from these high-grade deposits during the 1990s.

A recent VTEM survey combined with ground magnetics, detailed soil sampling and geological mapping has defined numerous high priority targets which are currently being drilled.


Drilling is underway on the  SE-01, gold target.  The target is located approximately 4 kilometres from the Kettle River gold mill in Washington State.

The SE-01 target was initially identified in Adamera’s VTEM survey as a high conductivity electromagnetic (EM) anomaly that coincides with a strong magnetic high. It represents the strongest conductor identified by the survey. Subsequent geophysical, geological and geochemical surveying has determined a possible strike length of +500 metres. 

SE-01 target is a combination of strong EM and magnetic anomalies with overlying soils enriched in gold,arsenic, copper, zinc and other metals.  Gold values directly overlying the target range from 18 to 350 ppb.

Another positive aspect of SE-01 is its position within 100 metres of the eastern bounding fault of the Republic Graben.  These major faults are associated with more than 90% of the gold deposits in the region.

Overlook/ Oversight Area

Adamera's drilling has identified two sources of gold mineralization on this property using two different methods of exploration.

  1. Shallow high-grade gold associated with silica alteration in high level clastic rocks. The shallow mineralization appears to be best targeted using soil geochemistry ranging from surface to 60 metres depth.
  2. Deeper high-grade mineralization occurs in massive sulfide/magnetite at the limestone clastic rock contact. This mineralization is highly conductive and detectible using an airborne VTEM survey. A recently flown VTEM survey has identified an 800 metre conductor on this property.

The Overlook Mine lies in the central part of this conductor leaving the northwest and southeast extent of the conductor important exploration targets for Adamera.

The most recent drilling was conducted near the past producing Overlook Mine. Several holes have intersected mineralization including a zone with 9.6 g/t Au over 10.9 metres. (see table)

Key West - Northern Extension

Adamera's Cooke Mountain property includes a large portion of the past producing Key West deposit. A VTEM survey has identified conductors extending out from the existing open pit mine and to the north along strike. Soil sample results exhibit gold, copper and arsenic anomalies associated with these conductors making these high priority targets.


Part of the Cooke Mountain project includes land on strike of the past producing Lamefoot deposit. Detailed soil sampling, ground geophysics, structural mapping and prospecting have developed targets similar to the Lamefoot deposit. Several targets have been outlined for drilling.

Martin St. Pierre P.Geoph, a Qualified Person as defined by National Instrument 43-101 has reviewed the data in this release.
