Key Highlights:
- Diamond drilling at Mazoa Hill confirms high-grade gold: 4.16 g/t gold over 23m, including 7.01 g/t gold over 11m.
- Diamond drilling at
Pancake Creek hits 25m grading 3.01 g/t gold from surface. - Diamond drilling of newly discovered shear zone at
Pancake Creek returns numerous anomalous intercepts.
Mazoa Hill Results
Note: Intervals in the reported holes are calculated using a cut-off of 0.3 g/t gold with maximum internal dilution of three continuous metres. Sampling is generally 1.50 or 1.00m in length, unless shorter for specific reasons, such as to honour geological contacts. There is insufficient geological information to ascertain whether intervals represent true widths. |
At Mazoa Hill, Golden Shield sought to test the deposit in a previously undrilled direction while simultaneously testing its depth extension. Hole MH24-40 intersected 23m grading 4.16g/t gold from 254m and 12m from 287m grading 6.74g/t gold (see Table 1), in an area of higher grade, but then deviated to the east and passed out of the favorable Ferruginous Quartzite ("FQ") lithology into unfavorable metavolcanics at 366m and stayed in metavolcanics until the hole was terminated at 417m.
Hole MH24-46 was drilled from the same collar location as MH24-40, but oriented further to the west. This hole quickly deviated beyond the allowed margins and was abandoned at 28m, without being sampled.

Hole MH24-47 was a re-start of hole MH24-47, also oriented west of MH24-40. This hole passed out the favorable FQ unit between 206 and 274m, where the high-grade intercept corresponding to that in MH24-40 was intercepted. Between these depths it passed into unfavorable metasediment, what may be an inlier within the FQ body. Below 274m the hole passed again into favorable FQ, intersecting 23m grading 2.69 g/t gold from 380m (see Table 1), but then passed again into unfavorable metavolcanics from 424m before being terminated at a depth of 621m.
The apparent base of the favorable FQ, defined by its lowest occurrence in Holes MH24-40 and MH24-47, appears to dip to the west, mimicking the "S" shaped folding pattern that is observed throughout the property (see Figure 3), and remains open in this direction and to depth.
This area corresponds to a coincident chargeability high feature as mapped by ground Induced Polarization ("IP") and magnetic low feature derived from a Calculated Vertical Gradient ("CVG") from ground magnetics. The chargeability high may indicate the presence of sulfide mineralization, that frequently carries gold at Marudi and the magnetic low may indicate the destruction of magnetite by gold bearing sulfidizing fluids. This geophysical signature has been confirmed to coincide with gold mineralization by drilling at Mazoa, as shown in Figure 4. A recent interpretation shows an undrilled area of approximately 400m by 250m with the same signature, possibly displaced by faulting, to the southwest of Mazoa, as shown in Figure 4. This represents a future drill target.

Hole LC24-44 also merits highlighting as the upper 25 meters graded 3.01 g/t gold from surface. Of these, the topmost 7.30 meters was logged as overburden and the uppermost 7 meters of this graded 6.19 g/t gold. As overburden, this may be transported material and may not reflect the grades of the underlying bedrock. Nonetheless, the bedrock below the upper 7 metres to graded 1.77g/t gold and this alone requires follow up. The diamond drill results in hole LC24-44 do not correlate well with nearby RC and this will require future investigation.
Hole PAN24-42, that contained shear zone hosted style pyrrhotite and pyrite mineralization and numerous anomalous intervals of gold mineralization, up to 9 meters long (see Table 2) also merits highlighting. Shear zone mineralization often occurs in lineaments within the shear zone ("shoots"); one diamond drill hole was insufficient to test this potential.

All Golden Shield sample assay results have been independently monitored through a quality control / quality assurance ("QA/QC") protocol which includes the insertion of blind standards, blanks as well as pulp and reject duplicate samples. Logging and sampling are completed at Golden Shield's core handling facility located at the Marudi property. Drill core is diamond sawn on site and half drill-core samples are securely transported to
pulverised and a 50-gram charge is analysed by Fire Assay with gravimetric finish. Golden Shield is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data referred to herein.
