Cooke Mountain Project


Drilling returns high-grade gold results on the Oversight IP anomaly on the Cooke Mt project.

19.4 g/t Au over 1.07 metres 

Drill terminated in the mineralized zone - Follow up drilling is planned to determine the extent of the zone.

See news release for full details and view images below.

Figure 1. Numerous IP anomalies, which warrant drill testing have been identified on the property. The map shows IP anomalies with coincident gold mineralization near the Overlook Mine, Outlook Ridge and Oversight area. Several IP anomalies are also coincident with anomalous gold in soil. The insert focuses on the two Oversight IP anomalies currently being drill tested. The current drilling has only tested a small portion of the 600 metre trend both laterally and along trend. Gold in rock samples are shown as blue circles and gold in soil samples are shown as red circles.

Photograph of core at end of hole OS18-02 shows strong alteration immediately before mineralized zone with 19.4 g/t gold. Drill hole tests IP anomaly and intersects high-grade gold.

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 have been drilled.

Cooke Mountain Trends - Overlook Trend and Lamefoot Trend

As a result of an aggressive 2017-2018 exploration program and interpretation of associated data and results, Adamera has defined two significant gold producing multi-kilometre trends within the Cooke Mountain Project. The two trends include the Overlook Gold Trend on the east side of the project and the Lamefoot Gold Trend on the west side. Both trends contain numerous untested and or drill confirmed targets.


Overlook Trend 


A.  Deep Overlook - Deep Overlook refers to the high-grade gold intercept of 9.6 g/t gold over 10.8 metres intersected below old workings of the Overlook Mine. The intercept was at a depth of 209 metres. The Company is currently generating a 3D model to determine how to best test the extent of this horizon. Final hole selection and any additional drill permitting should be completed in time for a July drilling start.


B.  Overlook Mine High-Grade Veins – Historic drill holes within the southern portion of the Overlook mine intersected shallow veins carrying significant mineralization, including a drill hole with 5 g/t gold over 45 metres. This style of mineralization is important as it reportedly contributed to half of the gold produced at the mine.

Adamera drilled two holes, OS17-01 and 03 approximately 300 metres from the Overlook Mine. Both holes intersected shallow zones of high-grade gold mineralization associated with quartz and sulfide veining. Intervals of significance include 6.5 g/t gold over 3 metres (including 10.3 g/t gold over 1.2 m), 9.3 g/t gold over 1.1 metres and 15 g/t over 0.3 metres.  A test induced polarization (IP) survey recently completed over the two drill holes generated an anomaly that warrants drill testing.



Prospecting For Overlook Style Veining - Anomalous gold in soils being detected directly above shallow vein occurrences suggests Overlook style veining is the source of such surface gold. Adamera has conducted extensive sampling resulting in anomalous gold in soils. These areas are devoid of magnetic or EM responses so remained untested. Such areas may have significant unrecognized potential for Overlook veining should IP surveying be confirmed as an effective prospecting tool.

Outlook Ridge is an occurrence of high-grade veins that was discovered by surface prospecting. Grab samples from several locations on a 1 km transect yielded gold values ranging from 8 to 69 g/t.  The planned IP survey will cover this area.



C.  Key West Mine Extension - VTEM conductors that extend 450 metres north of the Key West Mine were tested by two Adamera drill holes.  Multiple zones of significantly anomalous gold include up to 2.3 g/t gold over 4.4 metres. The highest gold values are associated with magnetite rich material in the drill core. Several zones of high magnetics within the VTEM anomaly are untested and warrants drilling.




Lamefoot Trend

The Lamefoot Trend is located 6 kilometres west of the Overlook Trend. The trend extends for 7 kilometres, with the historic Lamefoot gold deposit near its northern limit.

Adamera has identified two high priority areas on the trend that contain a number of compelling drill targets. These areas include the Lamefoot South and Goodfoot properties. The targets are based on a multi-discipline database compiled over the past several months.

Detailed work recently completed by Adamera includes: ground magnetics, electromagnetics to detect massive sulfides, induced polarization (IP) to detect sulfide veining and silica, and gold plus pathfinder element geochemistry.

Lamefoot South Property

Lamefoot South is located south of and contiguous with the Lamefoot Mine property. Seven targets with coincident magnetic, IP and soils gold anomalies have been identified on a limestone contact within a structural corridor on strike from the Lamefoot Mine. One target is defined by a 400 metre by 400 metre area located a few hundred metres south of the Lamefoot mine (See Figures 1A, 1B and 1C).

The targets are all interpreted to be shallow. A total of 15 drill sites have been submitted for permitting on state lands. Other drilling is planned on nearby private land where owner consent is the only requirement. Drilling is expected to begin in July or sooner.

Goodfoot Property

Goodfoot is located 2 kilometres south of the Lamefoot mine and on strike with the Anfo Fault, a key structure thought to control Lamefoot mineralization. Adamera has identified and mapped on the property 5 kilometres of stratigraphy known to regionally host high-grade gold mineralization. Coincident magnetics, IP, EM and soil anomalies have identified several shallow drill targets.

One of the best targets is estimated to be 25 metres deep and to extend for 300 metres (See Figures 2A, 2B and 2C). Approximately 15 proposed drill holes have been submitted for permitting.

Elsewhere, IP surveying on the Overlook Trend has recently begun and is targeting high-grade gold in quartz veins that were intercepted in Adamera Drill
