![]() of the Hope Mining Company Claims Resurrection Creek Valley, Alaska Al Johnson, Revised March 22nd, 2004
Location and Access
History Originally established in 1923, Hope Mining Company has conducted placer gold mining operations on Resurrection Creek south of Hope, Alaska. The Resurrection Creek Valley is an historic mining district; the first recorded discovery of gold was in 1888 and some historians believe that the Russians mined the area even before that date. By 1900, thousands of people occupied a thriving mining community in the Hope area, which was one of the principal mining camps in the state before the more widely known gold rushes in the Klondike and the Nome area drew the more foot-loose of the Hope miners away. Significant production continued in the Hope district until all gold mining nationwide was shut down for WWII. There was little activity in the area after the war but in the mid 1970’s the de-regulation of the price of gold sparked renewed interest and there has been mining on the creek ever since.
Land Status Production History From the turn of the last century until World War II, Hope Mining Company’s claims were mined using hydraulic equipment. Hydraulic mining utilizes large, high-pressure water nozzles to move and wash the placer deposits and to stack the tailings. In the years after World War II, there was little mining activity in the Resurrection Creek Valley due to post-war labor and material costs and a fixed price for gold of $35.00 per once. Interest in gold mining increased, however, with the de-regulation of gold and subsequent rise in the price of gold in the 1970’s. Since that time there have been several heavy-equip-ment operations conducted on Hope Mining Com-pany’s claims (Figure 3), typically consisting of machines such as bulldozers, excavators, and front-end loaders and a gravity recovery plant utilizing water moved by large pumps. According to the former U.S. Bureau of Mines (now part of the U.S Bureau of Land Management) the placers of the Hope Mining District as a whole have had an estimated total production of approximately 940,000 ounces of gold. Production figures for Hope Mining Company’s claims are shown in Table 1.
Geology According to the U.S. Geological Survey, the gold in the placer deposits in the Resurrection Creek drainage originated in quartz veins and igneous intrusions in the marine sediments of the surrounding Kenai Mountains. These rocks are of Cretaceous age and assigned by the U.S. Geological survey to the Valdez Group formation. The Valdez Group stretches along the south side of the Chugach Mountains from Kodiak Island to the Canadian border and hosts numerous lode and placer gold deposits throughout its extent. The broad U-shaped valleys of the Kenai Mountains were subjected to alpine glaciation in Quaternary time. The large prominent benches along Resurrection Creek consist of material deposited in a short period at the end of the region’s last glaciation. These sediments consist primarily of unstratified and poorly sorted sand and gravel with a few boulders dispersed in it. The gold was concentrated locally, but because of the rapidity of deposition, much was distributed throughout the deposit. A subsequent drop in relative sea level resulted in streams cutting down into the post-glacial gravels to form the present valleys, in the process reworking the gravels and further concentrating the gold. On some of the Hope Mining Company claims the gold concentrations are related to a "false bed rock" of yellow-gray glacial clay. This clay layer is of varying thickness and overlays unsorted gravel of about the same age and composition. Above the clay layer is a well-sorted Quaternary gravel with huge boulders resting right on the clay. Gold occurs throughout the gravel above the clay layer, but the highest pay is in the eighteen inches above the clay. As might be expected, the highest concentrations of gold are found beneath large boulders laying directly on the clay layer. The placer gold on Resurrection Creek tends to be fine-grained and flat. It averages 82-87% gold, with the rest primarily silver. Recent testing indicates significant values (up to .015 oz/ton) remain in the black sand concentrations after removal of the gold recoverable by present methods. Occasionally, small nuggets are found, some with quartz attached. Prior to World War II hard-rock (lode) gold mines were located east of Resurrection Creek in the Palmer Creek drainage (which empties into Resurrection Creek). Hope Mining Company has several gold claims on Palmer Creek, some of which are placer claims, and some of which are lode claims.
Placer Gold Deposits Potential placer gold reserves on Hope Mining Company’s claims occur in three types of deposits:
The modern stream gravels average 0.027 ounces of gold per yard based upon current testing and historical production data. The hydraulic tailings have been recently mined and tested and average about 0.017 ounces per yard. The benches are a much larger resource. They have not yet been mined, but according to testing done so far, average in the neighborhood of .017 ounces per yard. Table 2 gives estimated yardages for the three types of deposits, together with possible total gold contents and present gold values. Yardage estimates assume average depths of 12 feet for the modern stream gravels and tailings, and 21 feet for the bench gravels.
Conclusions Hope Mining Company has clear title to a very significant and verifiable gold resource in an established placer mining area. Gold has been profitably mined there for many years, and ongoing operations are planned and permitted. The property constitutes an excellent investment opportunity. The gold (and silver) resources summarized above are valuable assets belonging to a long-established and stable corporation. Professional Qualifications: Toni K.
