Every few months, a junior mining company publishes a press release announcing drill results. The headline tends to lead with the biggest number, a grade, an interval, a depth. For investors who know how to read these releases, the headline is a starting point. For investors who take it at face value, it can be the whole story.

That gap is very important. The mining sector runs on forward-looking information, and early-stage exploration updates are, by design, incomplete pictures. They are snapshots of one moment in a longer geological investigation. Reading them well does not require a geology degree. It requires knowing what the numbers actually represent, what verification steps should be present, and what language typically signals a rigorous operator versus one worth watching more carefully.

Start With the Assay: What Grade Actually Means

The Number Is a Concentration, Not a Certainty

An assay result is a chemical measurement. A laboratory takes a sample of drilled rock, called drill core, crushes it, and tests it to determine how much of a given metal is present per unit of weight. For gold and silver, the result comes in grams per tonne (g/t). For copper, it comes as a percentage of total weight. The grade tells you the concentration of metal in that specific sample from that specific location. It says nothing, on its own, about how much of the deposit exists, how continuous it is, or whether it could ever be economically extracted.

Context Transforms a Number Into Information

A result of 619.6 g/t silver means very little until you know the interval it came from, the depth at which it was intercepted, how it compares to surrounding holes, and whether the laboratory that produced the number follows internationally recognized quality protocols. Those details are not decorative. They are the analytical frame around the assay that allows an investor to assess what the number actually represents.

What Silver’s Supply Structure Tells You About Grade

Most Silver Comes as a Byproduct

About 70–80% of the world’s mined silver is produced as a byproduct of other metals, primarily copper, lead, and zinc (as of January 2025). The share from primary silver mines fell from roughly 32% before 2016 to around 28% in 2023 (as of January 2025). This structural reality has a direct implication for how investors should evaluate silver-dominant intervals in drill results: they are rare, and when a company reports genuinely high-grade silver in a drill hole, the geological significance is real. The supply system does not produce such grades easily or routinely.

King Global’s Silver Cord Result in That Context

At Silver Cord, King Global Ventures (CSE: KING | OTC: KGLDF | FSE: 5LM1) reported a Phase 1 highlight intercept of 9 feet (2.7 metres) grading 619.6 g/t (21.8 oz/tonne) silver, alongside 1.0 g/t gold, 0.6% lead, 1.05% zinc, and 375 g/t antimony (as of December 2025). The Black Canyon Project in Yavapai County, Arizona, 213 contiguous concessions across 4,000 acres encompassing 15 former operating mines, sits in a region with a documented history of base and precious metal production. The Phase 1 result confirmed a polyphase silver-lead-zinc-antimony vein system within the Spud Mountain stratigraphy, with Phase 2 drilling mobilized in February 2026 to test strike extensions and depth continuity. Understanding what that means, what “vein system,” “strike extension,” and “depth continuity” actually describe, requires understanding how intervals work.

Intervals: Length, Angle, and What “Including” Signals

Downhole Length vs. True Width

When a company reports “2.7 metres at 619.6 g/t silver,” that 2.7 metres is the downhole length, the distance along the drill hole where mineralization was measured. Reported intercepts often overstate true width because drill holes rarely intersect deposits at a perfect right angle. The actual thickness of the mineralized zone in the ground, its true width, is almost always equal to or less than the downhole measurement. In early-stage exploration, companies often disclose this caveat explicitly. The phrase “interval measurements are reported as core length” in a press release is a transparency signal, telling you what was measured and how.

The Word “Including” Is Worth Watching

A transparent company writes something like: “10 metres at 5.0 g/t silver, including 1 metre at 49.1 g/t.” The “including” signals that one narrow segment is carrying the headline number, while the broader interval grades lower. Approximately 73% of drill result announcements lead with the highest-grade intercepts, regardless of whether those intercepts represent the broader deposit. Reading the full assay table, not just the headline, tells you whether the high-grade segment is an isolated spike or representative of a wider mineralized system. Continuity across a zone is what transforms interesting geology into a resource.

QA/QC: The Verification Layer Most Investors Skip

What Quality Assurance Actually Requires

Under Section 3.3 of NI 43-101, Canadian exploration companies are required to describe the quality assurance and quality control measures applied during the work being reported on (as of 2025). In practice, a rigorous QA/QC program inserts three types of control samples into the sample stream submitted to the laboratory: certified reference materials, which are known-grade standards used to verify analytical accuracy; blanks, which are samples with no detectable metals used to check for contamination; and field duplicates, which are split samples run in parallel to test reproducibility. When a press release confirms that this program was in place and that no material QA/QC issues were identified, that sentence is doing significant work. It means the chain of custody from drill site to laboratory was intact and monitored.

Why Independent Lab Accreditation Matters

The laboratory running the assays needs to be independent of the company, because a conflict of interest in assay production is precisely what destroyed Bre-X. In 1997, Bre-X Minerals collapsed after core samples from the Busang site in Indonesia were found to have been salted with alluvial gold dust, fabricating one of the largest gold discoveries in history. The scandal cost investors billions and prompted the creation of Canada’s NI 43-101 disclosure framework. Today, independent laboratory accreditation provides a foundational check. ALS Geochemistry, the laboratory that analyzed King Global’s Phase 1 Silver Cord samples, operates all its hub laboratories under ISO/IEC 17025:2017 accreditation, the internationally recognized standard for testing and calibration laboratory competence (as of 2025). That accreditation means the laboratory’s procedures are independently verified and subject to ongoing audit.

The Qualified Person Standard: Who Signs Off and Why

NI 43-101 and the QP Requirement

NI 43-101 was created in the wake of Bre-X to ensure that all scientific and technical disclosure by Canadian-listed mining companies is based on information prepared by or under the supervision of a Qualified Person. A QP must be a licensed engineer or geoscientist with at least five years of relevant experience, be in good standing with a recognized professional association, and, critically, be independent of the company in most disclosure situations. The QP must review the raw assay certificates, geological logs, drill core photographs, and QA/QC data, then certify that the information disclosed is accurate and the methods are appropriate for the style of mineralization.

What a QP Signature Tells an Investor

When a press release names the QP and confirms their independence, it means a credentialed professional has staked their license and reputation on the accuracy of that disclosure. King Global’s Phase 1 results were reviewed and approved by Andrew Lee Smith, P.Geo., ICD.D, an independent Qualified Person whose verification work included confirming sampling procedures, chain-of-custody protocols, and QA/QC program integrity. The QP also confirmed that the analytical methods, including multi-element ICP-MS and ICP-AES, were appropriate for the style of mineralization encountered. For an investor, that confirmation is a layer of professional accountability that sits between the company’s interests and the information reaching the market.

Exploration Language Decoded

“Open at Depth” and “Open Along Strike”

Two phrases appear in nearly every exploration press release, and both carry real meaning. “Open along strike” means that exploration has not found the end of the mineralization in the horizontal direction, so the zone may extend further laterally than drilling has yet tested. “Open at depth” means the same applies vertically, that drilling has not yet reached the bottom of the mineralized system. Both phrases indicate that the known footprint of the deposit is a minimum, not a ceiling. King Global’s Phase 1 results confirmed mineralization remaining open in multiple directions, which is precisely why Phase 2 targets extensions of the high-grade intervals along strike and at depth.

“Uncut Assays” and What That Means

A note common in reputable press releases states that “all assay values are uncut.” This means no individual sample grade was artificially limited before being included in the reported averages. Some companies apply a top cut to very high-grade individual samples to prevent one spectacular result from distorting the reported average across an interval, a legitimate and often prudent practice. Reporting uncut values means the numbers you see are the raw results from the laboratory. Neither approach is inherently deceptive; understanding which one is being used helps you read the numbers accurately.

What King Global’s Disclosure Signals About the Project

A Corridor With Room to Grow

Every element of King Global’s Phase 1 disclosure, independent lab accredited to ISO/IEC 17025:2017, full QA/QC program with blanks and certified reference materials, named and independent Qualified Person, uncut assay values reported as core length, reflects the practices that the NI 43-101 framework was designed to mandate. The geological picture that disclosure paints is also significant on its own terms. The Silver Cord corridor confirmed a polyphase hydrothermal vein system carrying high-grade silver, lead, zinc, and antimony, with the IP anomaly beneath the mine interpreted as siliceous alteration and anomalous copper consistent with intrusive-related hydrothermal activity at depth. That copper signal, sitting beneath the Phase 1 polymetallic intervals, is one of the reasons Phase 2 drilling is testing the structural corridor at depth. The system has not been closed off. Mineralization remains open in multiple directions across a 4,000-acre land package in one of Arizona’s most historically productive base and precious metal districts.

The Early Stage Advantage

King Global is an early-stage exploration company, and early stage is exactly when the asymmetric opportunity is most accessible. Insider ownership above 65%, with zero management selling, means the people running the program are personally aligned with the outcome of the drilling. Phase 2 is underway. Results are flowing.
