The Lucky Mike Project is located 20 kms north of Merritt, British Columbia and within the Nicola Mining Division. The property is made up of 30 claim blocks totaling over 8,136 hectares and is accessed via a well developed network of logging roads. It is proximal to power, water, local labor force and is surrounded by several mining operations and new discoveries such as Highland Valley Mine, owned by Teck Resources, which is the largest copper mine in Canada. The MDP Project owned by Kodiak Copper, which is a new discovery and the New Afton Project owned by New Gold which is a high grade copper-gold alkali porphyry deposit. Then there is the shovelnose property to the south, currently being worked on by Westhaven Gold Corp.
The property is also home to a number of past producing silver mines with reported historic mining on the Property area highlighting shipments of 118 tons of ore with an average grade of 1 g/t Au and 2,014.8 g/t Ag. In addition to the past producing mines on the Property there are several key silver prospects yet to be explored by modern techniques.
Lucky Mike was first discovered in 1916 by prospector Oscar Schmidt. An inclined shaft dipping west followed the mineralized vein down dip for 35 meters and two short drifts were driven chasing the veins at 7m and 20 meters respectively. These areas produced a 22 ton ore sample which was sent out for processing and it returned grades of 4.66% Cu.
In 1926 the claims were optioned to Thelma Mines Ltd, who continued development work until 1930 with a 220ft shaft, drifting and crosscutting on multiple levels. The project was then optioned off to Sheffield Gold & Silver Mines ltd.
In 1934 Sheffield Gold & Silver Mines Ltd was mining on the property until a fire destroyed the head frame and building. At that point the claims were sold in a court order and remained inactive for the most part until the 1940’s
In 1942-43 W.B. Milner conducted numerous trenches and open cuts tracing the skarn 80 metres along a north-south strike. Two bands of skarn are separated by a greenstone unit. Numerous W03 values reneging from 0-1% to 1% occur over variable widths. Then, later in 1943 the Strategic Metals Committee part of the Wartime investigation for Tungsten drilled 14 diamond drill holes over a 100 metre strike length. Eight holes intersected a weighted average of 0.312% W03 over an average width of 25 feet. However no samples were assayed for gold or copper. The deposit was considered too low grade with poor continuity of scheelite mineralization.
Between 1958-65 Torwest Resources Ltd. conducted work including trenching, geophysical, geochemical and geological surveys. In addition, two or more drill programs were completed which consisted of 23 holes over 150 metre strike length on the Lucky Mike, skarn zone . Based on these programs plus 1943 data, Torwest defined two east dipping tungsten-skarn bodies.
In 1973, Consulting Engineer C.H.Donaldson estimated ” a drill-proven” reserves for the Lucky Mike deposit of 350,000 tons grading 0.56% copper, 0.30% W03, and 0.60 oz/ton silver.
In 1980, owner at the time W. Petrie dewatered and upgraded the old workings followed by a small sampling program. After that the project remained fairly inactive until the 1980’s, when Lacana was brought in to do more geological mapping and geochemical work in an attempt to create new targets around old workings.
Between July 10 and August 15th, 1986, Altar Resources Ltd completed detailed geological mapping, sampling, and geophysical surveys which resulted in outlining an oxidized zone 600 meters long, 25 to 70 meters wide with very encouraging silver assay results. A few samples were taken from this zone and assayed between 50.6 g/t Ag to 2,228.4 g/t Ag.
By 1988, Corona Resources acquired the property and had enough information that a drilling program was put in place to test the newly identified targets. In connection with this program, a comprehensive airborne geophysical survey was completed over what is now the southern half of the Rey Lake property. At this point it became clear that previous operators drilled down dip and ultimately missed they key target areas. Unfortunately, Corona could not conclude an agreement with the owners of the adjacent claim to Lucky Mike and thus allowed their option to lapse.
In July 1991, Strato Geological Engineering Ltd. completed a preliminary I.P. program for Hera Resources Corp. This was followed by a comprehensive I.P. survey conducted during the spring of 1993 and in turn, was immediately followed by a drilling program. This I.P. survey covered parts of the Southeast Sophia claim and just north of the Lucky Mike deposit. Drilling in 1993 took place just to the northeast of the Southeast Sophia claim.
In 2011, ArcPacific Resources (Formerly Plate Resources) optioned the property and did some exploration drilling of their own along with a range of geophysics. This project remained the main focus of the company until the name change to Arc Pacific in late 2016.
In 2011, PLATE funded an airborne geophysical survey over the property. Initial work included, an airborne geophysical program of 576-line km covering all but 3 new claims, by Precision Geo Surveys of Vancouver, British Columbia. This included magnetic and radiometric surveys and small program of sampling and mapping from the Lucky Mike and Sunshine mineralized areas.
Several magnetic anomalies were identified which appear to correlate with potassic radiometric responses, indicating that the intrusive plutons which have magnetite content also have potassic content, either as original K-feldspar components or as potassic alteration. This is consistent with the model for intrusive hosted copper porphyries.
On January 19, 2021 ArcPacific announced the completion of an extensive data compilation program resulting in the identification of highly elevated gold, copper and silver occurrences spread across the 8,136 hectare Lucky Mike Silver Lode Project. The work program compiled all available data including 75 separate reports dating back as far as the 1950’s into a single merged database. This data includes 11,306 rock, soil, silt and core samples containing 280,716 values for multiple elements, and multiple historic geophysical surveys. ArcPacific utilized this information to perform an extensive and in-depth detailed analysis of the project.
LMSL Litho-geochemistry Analysis Summary
As part of the data analysis, a review of the regional geological setting was also undertaken. It was determined that the LMSL Project is located along pronounced mineralized structural corridor stretching from Kodiak Copper’s MPD project and possibly all the way to New Gold’s New Afton Project. Given the project is also directly adjacent to Teck’s Highland Valley mine (as shown in Figure 1), the Project sits in a well-endowed region of BC.
The litho-geochemical analysis showed that geochemical signals in the Project area are consistent with a series of hydrothermal centers present at varying levels of exposure at surface. These range from the lithocap/advanced argillic environment down to a high temperature potassic level. Porphyry-epithermal signatures are present but are unusually associated with distinctively high silver values. This may represent overprinting events, or reflect high host rock reactivity and skarn formation during the early onset of an evolving system.
In the context of superimposed and genetically related skarn/porphyry systems, the patterns observed could be explained adequately. Carbonate horizons in the Nicola or Ashcroft likely captured early base and precious metal fluids as skarns and the evolving system could generate sericite in volcanic facies of the Nicola in proximity to said skarns.
It was also observed that the historic drilling in the Lucky Mike Area most likely focused on a very high level part of a porphyry system, within the molybdenite halo and on base with precious metals or “proximal skarns” within the surrounding stratigraphic horizons. If the system is tilted with the top towards the north-northeast, as suggested by the data, then a possible underlying porphyry is likely located within and adjacent to the molybdenum anomaly.
Swakum Mountain lies within the Intermontane Belt of the B.C. Cordillera. This belt includes a large number of major, past and present, porphyry copper producers, some of which occur in the Kamloops-Merritt district such as the Highland Valley and Afton. Much of the area consists of folded, Nicola Group (Triassic) Volcanics with minor inter bedded sedimentary units. These rocks are intruded by large north trending – felsic to intermediate intrusions (batholiths) east and west of the mountain. Nicola Group rocks on the mountain strike north to northeasterly with generally steep dips. For the most part they consist of andrsitic flows and tuffs, agglomerates, occasional basalt and rhyolites. A mixed volcanic sedimentary unit consisting of tuffs, limey sediments and a prominent limestone has northeasterly strike and crosses the Old Crown Grants on the mountain which spans over a 2.5 km strike length.
The Silver Lode Claims and Lucky Mike Project area is host to multiple styles of mineralization including silver-lead-zinc veins and replacements, polymetallic quartz veins, skarn type mineralization, and copper porphyry mineralization. Recent efforts have focused on the porphyry potential on the Property which remains open for additional exploration. The Property is situated in the Quesnel Terrane and is underlain by volcanic and sedimentary rocks of the later Triassic to early Jurassic Nicola Formation. These rocks have been intruded by Tertiary volcanics of variable composition.
