High-Grade Gold Exploration in Washington State
This profile is part of a paid investor education campaign.*
Adamera Minerals Corp. (TSXV:ADZ, OTC:DDNFF) is a junior exploration company looking to establish a high-grade gold deposit in Washington State, US. The company has four projects in northeastern Washington State, including three in the Republic gold district which has reportedly produced 6 million ounces of gold. Adamera’s flagship Cooke Mountain project encompasses five past-producing mines and contains two mineralized trends.
The Cooke Mountain project is strategically located near Kinross’ (TSX:K) Kettle River mill, which was put on care and maintenance when the Buckhorn mine was closed in 2017. The project is home to the high-grade gold, multi-kilometer Overlook and Lamefoot trends which host multiple high-priority targets and past-producing mines.
Key areas of focus for the project include the Key West and Lamefoot South targets. Drilling at Key West has returned intercepts of one meter grading 4.5 g/t gold, 2.3 meters grading 3.9 g/t gold and 1.07 meters grading 19.4 g/t gold. The Lamefoot South target meanwhile hosts a 400-meter by 400-meter area located 280 meters south of the historic Lamefoot mine.
Adamera also holds three additional projects in Washington State: Empire Creek, Flag Hill and Talisman. The Empire Creek and Flag Hill properties are also within the Republic gold district and are located near Kinross’ Kettle River mill and K2 mine. Both properties have returned one-meter intercepts grading 41 g/t gold. Adamera intends to conduct drill programs on the properties in the near term.
The historic Talisman copper–silver mine reportedly produced 521 tons of ore grading five percent copper, 102.9 g/t silver and 4.1 percent zinc in the early 1900s. Adamera’s initial exploration program yielded results as high as 144 g/t silver, 3.45 percent copper, 6.3 percent lead and 6.91 percent zinc. The company will be conducting additional mapping and prospecting to better define the mineralized zones on the property.

Adamera holds a substantial land position in the Cooke Mountain area in Washington State. The project encompasses five past-producing mines: Overlook, Lamefoot, Key West, Key East and Belcher. During the 1990s, approximately 1 million ounces of gold were mined from these deposits. The property is also located near Kinross’ Kettle River gold mill which has been placed on care and maintenance.
One property, two trends
A recent VTEM survey along with ground magnetics, detailed soil sampling and geological mapping has defined numerous high-priority targets that have been drilled. Adamera identified two significant gold producing, multi-kilometer trends on the property in its 2017 and 2018 exploration program. The Overlook gold trend rests on the east side of the project, and the Lamefoot gold trend on the west. Both trends contain numerous untested and drill-confirmed targets.
The Overlook trend hosts four past producing mines: Key West, Key East, Belcher and Overlook. The trend extends for over eight kilometers, and Adamera has confirmed high-grade mineralization in three areas that are on strike with the trend.
Underneath the Overlook mine workings, Adamera has identified high-grade gold in the magnetite and drilling returned intercepts of 10.8 meters grading 9.6 g/t gold and 2.1 meters grading 9.9 g/t gold. The 10.8-meter intercept was drilled at a depth of 209 meters. The company has developed a 3D model of the old workings of the mine to determine the best way to test the extent of the mineralized horizon and to generate new exploration targets.
The company has also identified shallow, high-grade gold veins throughout the Overlook trend. At the Oversight target, Adamera recovered samples grading up to 69 g/t gold. Drilling of the veins in 2018 returned intercepts of 1.1 meters grading 9.3 g/t gold and 2.8 meters grading 6.5 g/t gold.
In 2019, Adamera intersected 10.57 meters grading 2.5 g/t gold including two intervals grading 10.2 g/t gold and 11.2 g/t gold. The results indicate that this new gold trend falls within north-northeast trending IP anomalies and that the deposit is open to the north.
“This is a significant result. The information from our last three drill holes confirms a new north-northeast trending gold zone situated east of the Overlook mine in an area untested by drilling. Based on this information, we will now set out a drilling plan to test the extent of the zone,” said Adamera President and CEO Mark Kolebaba.
Adamera has recovered high-grade gold mineralization that extends from the Key West mine, which is approximately one kilometer north of the Overlook gold mine. Drilling has returned intercepts of one meter grading 4.5 g/t gold, 2.3 meters grading 3.9 g/t gold and 1.07 meters grading 19.4 g/t gold.
The Lamefoot trend is six kilometers west of the Overlook trend and extends for seven kilometers. The historic Lamefoot gold deposit lies near the trend’s northern boundary. Adamera has identified two high-priority target areas in the Lamefoot trend: Lamefoot South and Goodfoot. The company has completed an extensive work program over the trend that included ground magnetics, electromagnetics, an IP survey and geochemical surveys.
The Lamefoot South property is contiguous to and south of the Lamefoot mine property. Seven targets have been identified on the property that are coincident with magnetic, IP and in-soil gold anomalies. One target is defined as a 400-meter by 400-meter area located 280 meters south of the Lamefoot mine.
“The Lamefoot South property is ready to drill. Multiple layers of exploration data corroborate high priority targets proximal to a high-grade past producing gold mine. There is an old saying that states, the best place to look for a mine is close to a mine and in this case our data appears to reflect that possibility. Our top target is a strong magnetic and IP target with coincident gold and arsenic soil anomalies. The target is less than 300 meters from the Lamefoot mine, within the mineralizing structure and along the same or similar lithological contact. In my opinion, we couldn’t have a better drill target unless mineralization was sticking out of the ground,” said Kolebaba.
Through an extensive exploration program, Adamera has generated 15 high-grade gold targets that are ready for drilling. The company is in the process of creating a drill program to test the newly-identified targets.
The Goodfoot property is located two kilometers south of the Lamefoot mine and is on strike with the Anfo fault which is thought to control gold mineralization in the region. Adamera has mapped a five-kilometer-long stratigraphy that is known to host high-grade gold mineralization on the property. Magnetics, IP and EM surveys and soil anomalies have generated several drill targets. One of the targets is estimated to be 25 meters deep and extends for 300 meters. Adamera intends to complete approximately 15 drill holes on the property to follow up on high-priority targets.
“The Goodfoot targets are compelling. They are within and along the same geological setting as the historic Lamefoot mine and have similar characteristics. The Goodfoot property combined with the Lamefoot South property to the north form a multi-kilometer exploration opportunity along strike of a past producer. We look forward to the initiation of drilling this season,” said Kolebaba.
The Empire Creek property is located on the western margin of the Republic graben and is six kilometers south of Kinross’ K2 mine, which produced over 1 million ounces of gold. The property is also 15 kilometers north of the Republic gold district which hosts 3 million ounces of gold grading 20 g/t gold and 16 million ounces of silver grading 110 g/t silver.
Previous work on the property has returned three meters grading 40 g/t gold and 18 meters grading 9 g/t gold. A former operator completed one drill hole that returned one meter grading 41 g/t gold. Adamera intends to complete a VTEM survey over the property in the near term which will be followed up with drilling.
Flag Hill Mine
The Flag Hill mine resides within the Republic gold mine district and is located approximately one kilometer from the Eureka trend which has produced over 2.8 million ounces of gold grading 20 g/t gold and 15.8 million ounces of silver grading 110 g/t silver. The property is also located 10 kilometers from Kinross’ Kettle River mill.
Gold mineralization at Flag Hill occurs as epithermal veins with a reported average grade of 7.2 g/t gold. Only one drill hole has been completed 300 meters to the east of the property and intersected one meter grading 41 g/t gold. The mineralization at Flag Hill is also known to occur at shallow depths.
The Historic Talisman Copper-Silver Mine
The historic Talisman copper-silver mine is located in northeastern Washington State. The property is approximately 95 kilometers by highway from Teck Resources’ (TSX:TECK.A) Trail smelter in Canada.
Actual production records for the Talisman mine are not available; however, reports exist from the early 1900s that suggest 521 tons of ore was shipped from the mine grading five percent copper, 102.9 g/t silver and 4.1 percent zinc. Twenty grab samples were recovered from a 700-meter by 800-meter area southwest of the mine. The samples graded up to 144 g/t silver, 3.45 percent copper, 6.91 percent zinc and 1.24 percent lead.
Adamera’s initial exploration program yielded results as high as 144 g/t silver, 3.45 percent copper, 6.3 percent lead and 6.91 percent zinc. The company has also completed a magnetic survey on the property which identified a large magnetic anomaly to the west of the mine that may be associated with this mineralization.
Moving forward, Adamera will be conducting additional mapping and prospecting at Talisman to trace and better define the mineralized zones at the magnetic anomaly to the west.
