TORONTO, ON / ACCESSWIRE / November 25, 2020 / AEX Gold Inc. (AIM:AEXG)(TSXV:AEX), an independent gold company with a portfolio of gold licences in Greenland, announces an update to its 2020 exploration drilling campaign at its Nalunaq property in South Greenland. The results are complementary to the drilling results reported in a previous press release on October 21, 2020.
Objective of drilling program
To further develop the Company's understanding of the area to the south west of the deposit that is thought to be a parallel structure now known as "Valley Block".
This area has previously demonstrated good continuity of the Main Vein ("MV") through extensive drilling between 2017-2020 and returned high-grade intersections.
The 2020 infill drilling program was designed to understand the thickness and continuity of the Main Vein in the Valley Block.
Drilling result highlights
Further results from the Valley Block infill drilling programme include 52.4 g/t over 0.55 meters (AEX2008) and 5.9 g/t over 0.5 meters (AEX2009).
Visible Gold observed in AEX2009.
These results support the interpretation that Valley Block is a high-grade domain with a similar footprint to South Block.
Eldur Olafsson, CEO of AEX, commented:
"We are very encouraged at the prospective nature of the Valley Block following the delivery of further interesting drilling results from this year's drilling campaign. With previous drilling suggesting that the Valley Block has a similar footprint to other historically mined blocks at Nalunaq as evidenced by the thickness and continuity of the vein, we believe that there is significant potential in the area given the mineralized structure is open at depth and along strike. We are confident that with the implementation of an underground development program in the area next year, supported by a surface drilling program, will enable the Corporation to enlarge the Valley Block area in 2021."
Drilling in 2020 was designed to improve confidence in the Valley Block ahead of planned exploration underground development in this area in late 2021 / early 2022. This zone lies approximately 100 meters to the south of the South Block (Figure 1) and has now been drilled to 30 meters or closer drill spacing over an area of approximately 200 meters by 250 meters. Valley Block remains open along strike to the south west and is open at depth and up-dip.
Drilling at Nalunaq is primarily used to determine the presence of the Main Vein structure, with drilling generally under calling grades when compared to historical production due to the strong nugget effect observed at Nalunaq (see section below). Fundamental sampling error can also be high at Nalunaq due to geological heterogeneity resulting in the potential for with coarse gold being present in the unsampled half drill core, which remains in the core box.
Highlights from the second batch of assay results from the 2020 field season are shown in Table 1, with the location of the drillholes shown in Table 2.

A note on drilling at Nalunaq and the nugget effect - "Drill for structure, drift for grade."
The high variability of gold grades in high-nugget deposits such as Nalunaq means accurate estimation of grade from widely spaced drilling data alone is challenging. Historic operators of Nalunaq defined Mineral Resources based predominantly on underground channel sampling from development drives, and drilling was used as a guide to confirm the presence of Main Vein. A comparison of all past surface drilling in mined areas with block model grades (estimated using underground channel samples which reconcile with production) suggests that surface drilling typically under-calls gold grade (Figure 2). This phenomenon is not unique to Nalunaq, and AEX emphasises that whilst drilling is useful for identifying the mineralised structure, it may not be a reliable indicator of grade. With this in mind, the 2020 drilling program has been successful, locating the Main Vein structure in six holes. Ultimately, underground exploration development will be required in order to estimate grade and Mineral Resources above the Inferred category.
Figure 2 Main vein intercepts in historical drilling were compared to the nearest block in the official 2017 SRK block model (both datasets diluted to 1.5 meters mining width). Grades are plotted on the above scatter plot. Points highlighted in the red box represent historical drilling intervals that underreported the production grades. Dashed lines show 5 g/t Au cut-off, which was the historical mining cut-off grade. Note log scale.
Selective sampling of historic cores may have missed the Main Vein structure where there is subtle gold-bearing alteration and no well-developed quartz vein. To ensure all potential mineralisation is captured in the 2020 campaign, the entire length of the drill hole was half-core sampled. Samples were also assayed for 33 elements by ICP-AES with four-acid digestion to better understand the geochemistry of mineralised intersections. This dataset will support a future study investigating geochemical indicators for potential high-grade domains. Holes AEX1703 and AEX1707 from the 2017 drilling campaign were also re-examined and sampled over their entire lengths, although assays are pending.
Sampling and QAQC Disclosure
Drill core was cut in half using a diamond blade core saw. Where a bottom of hole orientation line was present, the cut line was marked approximately 5 degrees off axis, and the right-hand side of the core was sampled. Drill core samples were placed into calico or thick polymer bags with a sample ticket, weighed, and assigned a sample ID. Each sample was sealed with a security tag, which assigns a unique security ID to the sample. Samples were transported from site to an accredited laboratory for analysis; priority samples were sent to SGS Burnaby, BC, Canada and all remaining samples were sent to SGS Sudbury, ON, Canada.
Sample preparation scheme PRP94 was used on all samples, with the addition of a rotary split. This involves crushing to 75% passing 2 mm, rotary split off 1 kg, and pulverizing the split to better than 85% passing 75 microns. Samples were then analysed by 50g fire assay with ICP-AES finish, technique GE_FAI50V5 which has a detection limit of 0.001 ppm Au. Samples containing visible gold and samples considered to be the Main Vein were assayed with screen-metallics fire assay technique GO FAS50M which has a detection limit of 0.01 ppm Au. This involves screening 1 kg of pulverised sample to 106 µm followed by 50 g fire assay of the entire plus fraction and duplicate analysis of the minus fraction. In addition, all samples were assayed with a Four-Acid Digestion / 33 element ICP-AES package, technique GE_ICP40Q12.
The QA/QC program of AEX consists of the systematic insertion of certified standards of known gold content, and blanks, at a rate of 1 in 20 or 5% per QAQC type. In addition, SGS insert blanks and standards into the analytical process. The average sample mass was 2.08 kg.
