Northgold announces additional resource expansion drill results from its flagship Kopsa gold-copper project, including high-grade intervals at depth

MFN Publicerad: 10 Nov 2022 08:45

Northgold AB (Nasdaq First North Growth Market: “NG”, “Northgold” or the “Company”) is pleased to announce additional diamond drilling (“DD” or “core drilling”) results from its recently completed 2022 drill program across its 100%-owned Kopsa and Kiimala Trend projects in central Finland. Today’s announced gold assay results represent another four drill holes drilled at Kopsa, all of which encountered significant gold mineralization, with copper assays still pending.

Highlights

Highlighted gold assays from drill hole NGKOP22004 (copper assays are still pending) include:

0.63 g/t gold (“Au”) over 107.65m from 46m depth along hole (32.5m vertical depth), including:
- 1.43 g/t Au over 22.4m from 112.6m (79.6m vertical), which includes
  - 2.32 g/t Au over 8.3m from 119.7m (84.6m vertical), which includes
    - 15.72 g/t Au over 1m from 123m (87.0m vertical).

Highlighted gold assays from drill hole NGKOP22005 (copper assays are still pending) include:

0.78 g/t Au over 125.1m from 78.1m (55.2m vertical), including
- 2.21 g/t Au over 18.8m from 145.7m (103.0m vertical), which includes
  - 7.10 g/t Au over 3.2m from 150.5m (106.4m vertical).

Highlighted gold assays from drill hole NGKOP22006 (copper assays are still pending) include:

0.61 g/t over 34.45m from 108.4m (75.3m vertical), including
- 12.68 g/t Au over 0.4m from 108.4m (75.3m vertical), and including
- 1.22 g/t over 2.6m from 114.45m (79.5m vertical), and including
- 1.32 g/t Au over 7m from 130.55m (90.7m vertical), which includes
  - 4.14 g/t Au over 0.75m from 136.8m (95.0m vertical).

Highlighted gold assays from drill hole NGKOP22010 (copper assays are still pending) include:

0.66 g/t Au over 100.4m from 78.1m (55.2m vertical), including
- 2.74 g/t Au over 3.5m from 175m (123.7m vertical), which includes
  - 11.9 g/t over 0.7m from 177.8m (125.7m vertical).

Drill hole locations are shown in Table 1 and Figure 1.

Gold assay results are shown in Table 2, and Figures 2 and 3.

Drill holes NGKOP22004 and NGKOP22005 targeted extending the central main gold and copper mineralized zone eastward near its eastward extents where past drilling was more scarce. The holes encountered broad intervals (107.65-125m wide along hole) of low-grade gold mineralization (0.63-0.78 g/t Au) beginning at moderately shallow depths (55.2-79.6m vertical) which are intended to add to gold mineral resources by expanding previously scarcely defined mineralized zones and by in-filling gaps in past drilling or zones previously defined as waste rock, and also included high-grade intervals (7.1-15.72 g/t Au) of significant widths (1-3.2m wide along hole) at greater depths (from 87-106.4m vertical) near the bottom of the resource outline, that continue to require additional follow-up work to better understand the structural controls and potential of these high-grade zones at depth.

Drill holes NGKOP22006 and NGKOP22010 were drilled further south, just beyond the general southern extents of past drilling. These two drill holes traced roughly along or just outside the southern edge of the resource open pit shell or outline. The holes targeted down-dip SE continuations of the main mineralized zone in order to expand the southward limits of the deposit and by in-filling gaps in past drilling or zones previously defined as waste rock. These holes similarly encountered broad intervals (34.45-100.4m wide along hole) of low-grade gold mineralization (0.61-0.66 g/t Au) beginning at moderately-shallow depths (55.2-75.3m vertical) and included more discrete (0.7-0.75m wide along hole), high-grade intervals (4.14-11.9 g/t Au) at greater depths (from 95-125m vertical), which similarly continue to require additional follow-up work to better understand the structural controls and potential of these high-grade zones at depth.

Mitch Vanderydt, CEO, comments: “The team is excited about this tranche of drill results, which should add low-grade gold ounces to certain southern and lower portions of the Kopsa deposit in our interim resource update slated for early next year, and which also helps to further define some high-grade gold-mineralized zones near the bottom of the deposit, some of which may ultimately offer longer-term underground mining optionality in the future.”

Kopsa Historic Resource Estimate
Kopsa hosts a historic resource estimated at 16.3 million tonnes (“Mt”) at 0.81 grams per tonne (“g/t”) gold (“Au”) and 0.16% copper (“Cu”) for 423,600 ounces (“oz”) Au, or 554,600 oz gold equivalent (“AuEq”) at 1.06 g/t AuEq, the majority of which falls in the Measured and Indicated (“M&I”) category in accordance with Canada’s National Instrument (“NI”) 43-101 standards. See Northgold’s Independent Geologists Report (“IGR”) on the Company’s website for more information.

Update on 2022 Exploration Program
A total of 25 DD holes totalling 4,241 m were completed at the flagship Kopsa project during the 2022 drill program. Today’s announced results represent gold assays for four drill holes (Hole NGKOP22010 was extended from a depth of 212 m along hole to 412m, with gold assays still pending on the deeper portion). Gold assays were previously reported for three other drill holes (see press releases dated 2 August and 23 August 2022) and are pending on the remaining 18 drill holes (in addition to the deeper portion of hole NGKOP22010). Copper assays pending on all 25 holes. Additional assay results from Kopsa are scheduled to be released in the coming weeks.

Another five DD holes totalling 695 m were completed at Pirttineva (totalling 4,936m drilled company-wide during 2022), a previously un-drilled prospect at our Kiimala Trend project that looked promising based on a recently completed Induced Polarization (IP) geophysical survey and outcrop samples (see press release dated 12 September 2022), with assays pending on all five holes which are scheduled to begin to be announced in the coming weeks. Multiple sulfide-bearing zones were observed in portions of the core.

Qualified person
The technical information in this press release has been reviewed by Dr Hannu Makkonen from Suomen Malmitutkimus Oy. He has over 40 years of experience in mineral exploration in Finland, he is a European Geologist (EurGeol) and a Competent/Qualified Person as defined by the PERC Reporting Standard 2021, JORC Code, 2012 Edition, and by National Instrument 43-101 – Standards of Disclosure for Mineral Projects. Dr Makkonen owns no shares in Northgold AB, or its wholly-owned subsidiaries, Fennia Gold Oy or Lakeuden Malmi Oy.

Quality assurance and quality control (QA/QC)
Drill core is logged, sampled and cut in half by a diamond saw in a secure core storage facility located in Pyhäsalmi Mine site, Finland. The core samples were sent to Eurofins Mineral Testing laboratory in Oulu, Finland, for sample preparation. From Oulu, the samples were sent to Eurofins Mineral Testing laboratory in Sodankylä for PbO fire assay and ICPOES analysis (method code: 705P). Certified reference standards and blanks were included in the sample batches. In four standard assays out of fifty a deviation, low in absolute values ( + 0.033 – 0.089 g/t Au) but relatively notable (14.2 - 38.4%) was observed. Otherwise no QAQC issues were noted with the results reported herein and their values allow the public disclosure of the assay results. Eurofins Mineral Testing Finland is accredited according to ISO/IEC 17025 by FINAS.
