Minaurum Drills High-Grade Silver on the Quintera Vein Zone at the Alamos Silver Project: 5.30 m of 570 g/t Ag, Including 2.50 m of 1,024 g/t Ag and 5.80 m of 581 g/t Ag
MWN-AI** Summary
Minaurum Silver Inc. has announced encouraging high-grade silver drill results from its Alamos Silver Project in Sonora, Mexico, specifically within the Quintera and Europa Vein Zones. These results come amid a substantial Phase II resource expansion program, which entails 50,000 meters of drilling.
Notable highlights from the drilling include a significant intersection of 5.30 meters yielding 570 g/t silver (633 g/t silver equivalent) from Hole AL26-180W, with a standout segment of 2.50 meters at an impressive 1,024 g/t silver (1,120 g/t AgEq). Another hole, AL26-188, recorded 5.80 meters averaging 581 g/t silver (658 g/t AgEq). These findings suggest strong potential for further high-grade mineralization within previously unexplored veins, which were not accounted for in Minaurum’s initial resource estimates.
According to Darrell Rader, the company’s CEO, these results bolster confidence in expanding resource estimates, particularly from the Quintera vein zone, historically mined up to 1908, averaging significant silver and copper grades. Six drill rigs are currently operational at the Alamos project, targeting resource expansion across multiple vein zones, including Europa, which has also shown promising continuity and high-grade intersections.
Minaurum aims to incorporate these findings into an updated resource estimate expected in the latter half of 2026, reinforcing the exploration strategy focused on advancing its high-grade silver assets. With the continuous drilling efforts and positive assay results, Minaurum is strategically positioned to enhance shareholder value while exploring its production-permitted properties in Mexico.
MWN-AI** Analysis
Minaurum Silver Inc. (TSXV: MGG) has recently reported promising high-grade silver drill results from the Quintera and Europa vein zones at the Alamos Silver Project in Sonora, Mexico. The standout results include 5.30 meters of 570 g/t silver, with sections yielding even higher grades, such as 2.50 meters of 1,024 g/t silver. These results are critical as they indicate strong mineralization potential in previously unassessed areas, which could enhance overall resource estimates.
Investors should take note of several key factors. First, the ongoing Phase II drilling program comprises a substantial 50,000 meters, indicating Minaurum's commitment to resource expansion. Successful resource expansion typically drives stock valuations in the mining sector, suggesting favorable market sentiment ahead.
Furthermore, historical context adds to the optimism; the Quintera vein historically held significant mineralization (averaging 40 oz/t Ag), indicating it could once again be a lucrative asset. The current grades reported are considerably high and underscore the area's potential, particularly as the silver market shows resilience against price fluctuations.
With six drill rigs operational and consistent high-grade results reported, Minaurum is positioned to deliver a substantial updated mineral resource estimate in the latter half of 2026. Investors might find value in entering or expanding positions in Minaurum prior to this potential update, as positive results likely will attract increased interest.
Nevertheless, potential investors should remain cautious and consider risks such as fluctuating silver prices, operational challenges, and delays in resource estimates. Given the robust findings to date, maintaining a watchful eye on developments in drilling and market conditions will be crucial for informed decision-making. Overall, Minaurum Silver appears well-positioned for growth, making it an attractive prospect within the silver mining sector.

Vancouver, British Columbia--(Newsfile Corp. - March 31, 2026) - Minaurum Silver Inc. (TSXV: MGG) (OTCQX: MMRGF) ("Minaurum" or the "Company") is pleased to report high-grade drill results from both the Quintera and Europa Vein Zones, as part of its ongoing Phase II, 50,000-metre resource expansion program at the Alamos Silver Project ("Alamos") in Sonora Mexico.
Highlights include:
- 5.30 metres of 570 g/t silver (633 g/t silver equivalent "AgEq"), including 2.50 metres of 1,024 g/t silver (1,120 AgEq) (Hole AL26-180W)
- 5.80 metres of 581 g/t silver (658 g/t AgEq) (Hole AL26-188)
"These drill results at Quintera highlight the strong potential to define and expand high-grade mineralization in vein zones not included in Minaurum's initial Mineral Resource Estimate. At Europa, ongoing step-out drilling to the south continues to demonstrate excellent continuity, with several high-grade intersections," stated Darrell Rader, President and CEO of Minaurum Silver. "With consistent high-grade results across multiple vein zones, including the newly tested Quintera zone, Minaurum remains on track with its fully funded 50,000-metre drill program and is well positioned to incorporate these results into an updated mineral resource estimate in the second half of 2026."
The Quintera vein zone was mined along approximately 800 m of strike length and to depths of 500 m and runs parallel to the Travesia vein zone merging with it to the north. Historical records indicate that the La Quintera mine closed in 1908 due to a drop on the silver price while still in mineralization averaging 40 oz/t Ag and 8% Cu (see news release dated December 14, 2016 and February 6, 2020). Quintera was not included in Minaurum's inaugural mineral resource estimate and will be incorporated into the resource update.
Minaurum is operating six drill rigs at the Alamos project, focused on expanding resources along strike and at depth at the Europa and Promontorio-Travesia vein zones, while also carrying out resource-definition drilling at San Jose, Quintera, Cotera-Pulpito, and Minas Nuevas (Figure 1).

Data review and verification: Stephen R. Maynard, Vice President of Exploration of Minaurum and a Qualified Person (QP) as defined by National Instrument 43-101, reviewed and verified the assay data, and has approved the disclosure in this news release. Verification was done by visual inspection of core samples and comparison to assay results. Assay results have not been checked by re-analysis. No factors were identified that could materially affect the accuracy or reliability of the data presented in this news release.
Analytical Procedures and Quality Assurance/Quality Control: Preparation and assaying of drilling samples from Minaurum's Alamos project are done with strict adherence to a Quality Assurance/Quality Control (QA/QC) protocol. Core samples are sawed in half and then bagged in a secure facility near the site and then shipped either by a licensed courior by Company personnel to ALS Minerals' preparation facility in Hermosillo, Sonora, Mexico. ALS prepares the samples, crushing them to 70% less than 2mm, splitting off 250g, and pulverizing the split to more than 85% passing 75 microns. The resulting sample pulps are prepared in Hermosillo and then shipped to Vancouver for chemical analysis by ALS Minerals. In Vancouver, the pulps are analyzed for gold by fire assay and ICP/AES on a 30-gram charge. In addition, analyses are done for silver, copper, lead, and zinc using 4-acid digestion and ICP analysis. Samples with silver values greater than 100 g/t; and copper, lead, or zinc values greater than 10,000 ppm (1%) are re-analyzed using 4-acid digestion and atomic absorption spectrometry (AAS).
Quality-control (QC) samples are inserted in the sample stream every 20 samples on average, and thus represent 5% of the total samples. QC samples include standards, blanks, and duplicate samples. Standards are pulps that have been prepared by a third-party laboratory; they have gold, silver, and base-metal values that are established by an extensive analytical process in which several commercial labs (including ALS Minerals) participate. Standards test the calibration of the analytical equipment. Blanks are rock material known from prior sampling to contain less than 0.005 ppm gold; they test the sample preparation procedure for cross-sample contamination. In the case of duplicates, the sample interval is cut in half and then quartered. The first quarter is the original sample, the second becomes the duplicate. Duplicate samples provide a test of the reproducibility of assays in the same drilled interval. When final assays are received, QC sample results are inspected for deviation from accepted values. To date, QC sample analytical results have fallen in acceptable ranges on the Alamos project.
When final assays are received, QC sample results are inspected for deviation from accepted values by the QP. To date, QC sample analytical results have fallen in acceptable ranges on the Alamos project.
