2021 Exploration Program

The 2021 exploration program on the Project is a continuation of the work initiated in 2020 that included a compilation of historical information and reports and completion of its high-resolution airborne magnetics and time-domain electromagnetic data collection over 203 line-kilometers at 100m spacing.  Several geophysical anomalies were identified and targets for follow-up were recommended.  Marvel’s geological team began the 2021 program work of prospecting, bedrock mapping and rock sampling.  Trenching is being done for further definition of the gold mineralization associated with the known anomalies and geological structures.  Diamond drilling is underway with 16 drill holes planned for the summer field season.  

Phase One (1,116.25m)

Highlights from the drilling program include:

Black Fly Northeast Zone (Figure 2)

  • Drill hole BF21-19 intersected multiple gold domains, including 6 g/t gold over 0.5 m from 39.2 – 39.7m and together with hole BF21-18, extends the Black Fly Northeast Zone by 130 m to the northeast.

    Black Fly Main Zone (Figure 3)
  • Drill hole BF21-13 intersected 06 g/t gold over 9.3 m from 14.3 – 27.7m.
  • Drill hole BF21-16 intersected 79 g/t gold over 7.7 m from 7.3 – 15.0 m.
  • Drill hole BF21-14 intersected a broad mineralized zone with 2 m grading 0.21 g/t gold, including 1.74 g/t gold over 1.0 m.

    Mosquito Zone
  • Drill hole BF21-15 intersected multiple gold domains, including 96 g/t gold over 0.3 m from 7.7 – 8.0 m, corresponding to the 2021 discovery of up to 52.5 g/t gold in a grab sample. Visible gold was noted in this hole (see press release dated August 3, 2021) at 7.7-8.0m downhole.

    Deer Fly Zone
  • Drill hole BF21-17 intersected multiple gold domains, including 10 g/t gold over 2 m from 40.0 – 42.0 m.

    Black Fly Northwest Zone
  • Drill hole BF21-13 intersected 93 g/t gold over 6.7 m from 105.7 – 112.4 m including 1.42 g/t gold over 4.0 m from 108.4 – 112.4 m.

QA/QC and Core Sampling Protocols

Samples collected in 2021 were analyzed by Activation Laboratories, an ISO/IEC 17025:2017 accredited facility.  Drill core was logged and sampled in Marvel’s secure facility located near Atikokan, Ontario.  Samples were obtained by cutting the core in half using a diamond cutting saw and were stored in Marvel’s secure field office until their transportation by Marvel personnel to Activation Laboratories’ sample preparation facility in Thunder Bay, Ontario. Gold was analyzed by fire assay with an Atomic Absorption finish; samples with >5 g/t Au were re-analyzed by fire assay with gravimetric finish. Certified gold reference standards, field duplicates and blanks were regularly inserted into the sample stream. Selected samples were also chosen for duplicate assay from the coarse reject of the original sample. Gold results from the holes reported herein varied from below detection to 50.06 g/t. No quality control/quality assurance issues were noted with the results reported herein.

Field Mapping and Sampling

Gold mineralization on the Blackfly Gold Project is clearly being presented in several hosts and with varied mineralized styles, ranging from traditional gold in quartz veins to gold occurring in highly altered host rocks.  Mineralization is developed within altered northeast trending, steeply dipping structures that obliquely cut the regional foliation.

  • First round of 2021 surface sample highlights:
    • 40 of the 78 samples returned assays greater than 100 ppb gold
    • 7 samples graded from 1.00 g/t and up to 2.99 g/t gold
    • 15 samples in excess of 3.00 g/t gold of which 4 samples assayed greater than 10 g/t gold with coarse visible gold noted in sample W1069699 that assayed 24.3 g/t gold

Airborne Geophysical Data

ProspectAir of Gatineau, Québec completed the surveys which consisted of high-resolution airborne magnetics and time-domain electromagnetic data collection over 203 line-kilometers at 100m spacing.

The magnetic anomalies as denoted by the orange to red to purple zones on the map occur as bands of highly magnetic bedrock.  TerraX Minerals Inc. reported in 2012 that the geology of the Property comprised bands or lenses of mafic volcanic units within intrusive tonalite and diorite.  The mafic rocks were noted as being modestly to highly magnetic with approximate northeastward strikes.

The principal gold occurrences including the zones where the Blackfly shaft occurs are associated with a dominant magnetic high cutting through the central part of the Property.  In addition, ProspectAir stated that the gold occurrences are associated with a strong V-folded magnetic feature in the middle of the property.  The Company believes that it can target new gold mineralization along the magnetic feature that contains the Blackfly Main, Northeast, and Southwest gold zones over its 5 km length. 

Assessment file records indicate that the original Blackfly gold discovery was made in 1897, making the occurrence one of the earliest found in the Atikokan gold mining camp.  The project’s 45-foot shaft was sunk in 1898 shortly after gold was discovered.  Several companies have added to the database of the Property including: Rebair Gold Mines Ltd. (1945 to 1948), Steeprock Mines Ltd. (1949 and again in 1961), Aavdex Corporation (2004) and TerraX Minerals Inc. (2009 to 2012).
