Meridian Mining UK. S (TSX: MNO), (Frankfurt/Tradegate: 2MM) (OTCQB: MRRDF) ('Meridian' or the 'Company') is pleased to report further strong drill results from its resource delineation program at the Santa Helena Au-Cu-Ag & Zn VMS deposit ('Santa Helena').
Drilling has intercepted multiple bands of shallow mineralization highlighted by CD421's 11.3m @ 3.7g/t AuEq1 from 35.0m, including 3.4m @ 8.6g/t AuEq from 42.9m. CD-421's high-grade mineralization projects outside of the modelled limits of Santa Helena's Exploration Target announced in December 20232 , strengthening the upside potential that Santa Helena's drill results have delineated. The Company is also confirming a major extension of the along strike extent of Santa Helena's mine horizon with CD-431 returning 5.4m @ 0.7g/t AuEq from 38.4m, located 580m east of the historical mine's limits. This extends the focus of Santa Helena's open pitable resource delineation corridor to 1.6km, requiring further infill drilling while yet still remaining open to the east. Drilling programs continue at the Cabacal Project with further results pending.
HIGHLIGHTS REPORTED TODAY Santa Helena assays multiple bands of Au-Cu-Ag & Zn mineralization extending past the Exploration Target's limits: o CD-421: 11.3m @ 3.7g/t AuEq3 from 35.0m; Including: 3.4m @ 8.6g/t AuEq from 42.9m;/ o A 320m strike extension of Santa Helena's lower Au-Cu-Ag & Zn layer defined and remains open; Santa Helena's open pit target corridor expanded to over 1.6km but still remains open to the east; o VMS system confirmed to extend outwards past historical mine's limits by 580m; o CD-431 returns 5.4m @ 0.7g/t AuEq from 38.4m and Results confirm that Santa Helena 3km mine horizon's IP anomaly remains only partially tested and remains open.
Mr. Gilbert Clark, CEO, comments: 'As part of the Cabacal hub and spoke development strategy, Santa Helena is adding more high-grade gold-copper-silver and zinc mineralisation into this highly prospective VMS belt. CD-421 also gave another along strike extension to Santa Helena's newly identified lower VMS sequence, combining to add more Au-Cu-Ag & Zn mineralization to an already expanding deposit. Most importantly, the near mine eastern extension is firming up with CD-431's results, extending the potential a further 580m. Having Santa Helena's mineralization and its extension consistently hosted within the 3km
SANTA HELENA DRILL PROGRAM UPDATE
Santa Helena is a historical Cu-Au-Ag & Zn VMS mine located 9km to the southeast of the Cabacal Mine. It has over 10,000m of historical drilling and is the most advanced of a series of exploration targets along the Cabacal Mine Corridor. The Company commenced initial drilling in August 20234 as part of a verification program, to validate the historical mine's data in line with NI43-101 requirements, and to initiate scout drilling of targets for resource extensions defined by geophysics and coincident geochemical anomalies. The Company's compilation of historical drill data indicated that many past holes were not completely sampled, that reconciliation of surveyed drilled positions and mine workings (and records), indicated that the high-grade massive sulphide mineralization was only partially mined, and that extensions of near-surface mineralization to the east were also not integrated into the historical resource calculations. The Company has concluded that this historical resource area is considered open, and based on new and historical data, defined an Exploration Target of 3.2 - 7.2 Mt @ 3.0 - 3.2g/t AuEq5 . The Company has completed thirty holes for 1730m to date. Initial results from holes drilled along the main trend for resource verification and resource extension were very positive6 . The latest results have continued to define mineralization up-dip and south of the historical resource limits and confirmed that the eastern sector of the trend remains open.
CD-421 was drilled to test the continuity of up-dip mineralization on the southern flank of the deposit. The drill hole intersected an upper mineralized zone of 11.3m @ 3.7g/t AuEq (1.1g/t Au, 1.5% Cu, 27.9g/t Ag & 2.0% Zn) from 35.0m, including a higher grade core of 3.4m @ 8.6g/t AuEq (2.2g/t Au, 3.2% Cu, 64.4g/t Ag & 5.5% Zn) from 42.9m. Lower bands of mineralization were present, including 12.3m @ 0.7g/t AuEq (0.1g/t Au, 0.1% Cu, 4.6g/t Ag & 1.0% Zn) from 58.5m, and 3m @ 0.4g/t AuEq (0.1g/t Au, 1.6g/t Ag & 0.6% Zn) from 79.7m. The latest result continues the eastward extension of strong intersections previously reported over the southern extension of the chargeability anomaly. Further scope exists to test the response to the immediate east over a 200m gap in the drilling, and beyond where numerous geophysical targets have been defined. CD-431, positioned up to 580m to the east of the historical mine's limits, was drilled as one of the Company's initial reconnaissance holes testing the 2km eastern extension of the IP anomaly. The hole was significant in confirming this trend is mineralized, returning 5.4m @ 0.7g/t AuEq (0.4g/t Au, 27.8g/t Ag & 0.4% Zn) from 38.4m. The mineralization was intersected below an upper carapace gabbroic sill which masks the surface geochemical response of this trend. A further reconnaissance hole, located over 840m further east southeast again, intersected traces of shallow bedrock mineralization. Further geophysical work is being conducted to refine targets in this eastern corridor and remains in progress, with a Fixed Loop Transient Electromagnetic Survey in progress (FLTEM) to supplement the existing IP dataset. Anomalies are expected to be quite subtle, given the limited conductivity of sulphides in the presence of sphalerite, but potentially more copper-rich targets may have enhanced conductivity
Cabacal is a gold-copper-silver rich VMS deposit with the potential to be a standalone mine within the 50km VMS belt. Cabacal's base and precious metal-rich mineralization is hosted by volcanogenic type, massive, semi-massive, stringer, and disseminated sulphides within deformed metavolcanic-sedimentary rocks. A later-stage gold overprint event has emplaced high-grade gold mineralization. The Preliminary Economic Assessment technical report (the 'PEA Technical Report') dated March 30, 2023, entitled: 'Cabacal Gold-Copper Project NI 43-101 Technical Report and Preliminary Economic Assessment, Mato Grosso, Brazil' outlines a base case after-tax NPV5 of USD 573 million and 58.4% IRR from a pre-production capital cost of USD 180 million, leading to capital repayment in 10.6 months (assuming metals price scenario of USD 1,650 per ounces of gold, USD 3.59 per pound of copper, and USD 21.35 per ounce of silver). Cabacal has a low All-in-Sustaining-Cost of USD 671 per ounce gold equivalent for the first five years, driven by high metallurgical recovery, a low life-of-mine strip ratio of 2.1:1, and the low operating cost environment of Brazil (see press release dated March 6, 2023). The Cabacal Mineral Resource estimate consists of Indicated resources of 52.9 million tonnes at 0.6g/t gold, 0.3% copper and 1.4g/t silver and Inferred resources of 10.3 million tonnes at 0.7g/t gold, 0.2% copper & 1.1g/t silver (at a 0.3 g/t gold equivalent cut-off grade), including a higher-grade near-surface zone supporting a starter pit.
