Further High-Grade Gold Intercepts at Blue Moon Prospect, Bailieston, Victoria

ECR Minerals plc (LON: ECR), the exploration and development company focused on gold in Australia, is pleased to announce results for three more drill holes from the Blue Moon Prospect, Bailieston, Victoria, including our best gold intercept for this 2022 drilling campaign in hole BBMDD010.

ECR Minerals plc has 100% ownership of the Bailieston Project (EL5433), which contains the gold prospects known as HR3, Cherry Tree, Blue Moon and Black Cat. The projects are operated by ECR’s wholly owned Australian subsidiary Mercator Gold Australia Pty Ltd (“MGA”).

ECR CEO Andrew Haythorpe commented: “The Board are pleased to report further drill results from Blue Moon, with the drilling campaign almost complete, and that we have for the most part seen continuity of grades across results from the holes announced today. As largely expected by the geo team, the best result came from hole BBMDD010, with an impressive composite grade of 6.35m @4.56 g/t from 84.9m down. With the modelling for Blue Moon nearly complete, we are close to finalising our plan of action here for 2023.”

“My thanks to Adam Jones and the team for working through the logistical challenges encountered during the campaign, and I look forward to reporting next steps for Blue Moon on receipt of assays for holes BBMDD012 and BBMDD013 in the next few weeks.”

HIGHLIGHTS

• Results from drillholes BBMDD009, BBMDD010 and BBMD011 received

• Best results from hole BBMDD010 include 0.5m @ 17.77 g/t Au from 84.9m, 0.4m @ 15.02 g/t Au from 85.4m and 0.3m @ 10.62 g/t Au from 85.8m.
• Results include 0.4m @ 0.25 g/t Au from 205.2m (BBMDD009).
• 1m @ 0.72 g/t Au from 95m (BBMDD011).

OPERATIONAL UPDATE

Diamond drilling has now been completed at Blue Moon, with the Midas rig demobilised on the 23^rd February 2023. Midas will undergo a service before delivery to the Brewery Lane property at Creswick (EL006184). The rig is expected to be up and drilling within the property boundary by mid to late next week, and drilling is scheduled to follow up on the RC drill results from the 2019 Creswick campaign. The Board has also planned a number of drillholes into the quartz reef (Spring Hill Reef) where recent high grade rock chips in situ were taken from the walls of the historic workings (see RNS dated February 7 2023 here).

BBMDD009-010-011 RESULTS

Drillhole BBMDD009 was designed to test the deeper levels of the Blue Moon dyke vertically below the best previous intercept in hole BBMDD004 of 0.5m @ 7.29 g/t Au. Although the dyke target was intercepted in hole BBMDD009 at a depth of 200m, the contained gold was negligible, with 0.4m @ 0.25 g/t Au from 205.2m the best result.

Site access and wet weather hampered access to drillholes BBMDD010 and BBMDD011 at the start of the campaign. Both drillholes were designed to test the shallower levels of the Blue Moon dyke either side of ECR’s best intercept to date in RC hole BBM007 (11m @ 5.13 g/t Au from 55m). Once drilling at BBMDD010 commenced, an immediate increase in the width of the hosting dyke became apparent, supported by the best drill intercepts from the current drilling campaign including 0.5m @ 17.77 g/t Au from 84.9m, 0.4m @ 15.02 g/t Au from 85.4m and 0.3m @ 10.62 g/t Au from 85.8m. Grouped together, the intercepts from 84.9m depth composite together at a grade of 6.35m @ 4.56 g/t Au (using a cut-off of 1 g/t Au).

Drillhole BBMDD011 did not contain any significant value, with a best intercept of 1m @ 0.72 g/t Au from 95m depth.

The drilling of earlier holes BBMDD004 to BBMDD008 was designed to test the possible extent of mineralisation to the west. If the drill results from these initial holes had proven successful, the known strike extent of Blue Moon will effectively double.

RECOGNITION OF POTENTIAL HIGH GRADE GOLD TREND AND NEXT STEPS

Drilling into the Blue Moon Project between 2018 and to date includes 12 diamond drill holes and 12 RC drill holes. Plotting the best intersections to date onto a long-section profile along strike of the Blue Moon dyke does, in the opinion of the Board, indicate the presence of a high-grade gold shoot, which may plunge moderately to the west under hole BBMDD004 (refer to Figure 2 above). A lineal trend plots between high grade gold intercepts in hole BBM004 (RC drilled), hole BBMDD004 and hole BBMDD010 (diamond drilled). The last drilled hole BBMDD013 is targeting the downward trend of this hypothetical shoot. The presence of some high grades from Blue Moon drilling results to date is encouraging, although the width and strike of the predicted grade plunge is narrower than at first thought. Once results from holes BBMDD012 and BBMDD013 are received (anticipated in the next two to three weeks) the Board can finalise a 2023 plan of action for Blue Moon.
