Bankable Feasibility Study! 🤑 🫢

In the past few weeks, I’ve received several questions from investors and licence holders about Bankable Feasibility Studies (BFS)—what they cost, how much land is needed, who buys the project afterwards, and whether it’s worth doing one for gold. These are important questions for anyone serious about developing a mining asset.

What does a Bankable Feasibility Study cost?
A BFS is the highest level of technical and financial confidence in mining. Depending on the scale and complexity, costs typically range from USD 1.5M to 15M+. It includes mine design, metallurgy, geotechnical work, environmental studies, tailings design, and full financial modelling.

How big should the land be?
There is no fixed requirement. The land must simply cover the orebody and all mine infrastructure—processing plant, tailings facility, waste dumps, water dams, workshops, and buffer zones.
Small underground mines may need 5–20 ha
Medium open pits may require 200–500 ha

Who buys a project after a positive BFS?
A BFS transforms a licence into a financeable asset, attracting:
Mid‑tier and major mining companies
Private equity mining funds
Royalty and streaming companies
Strategic investors and regional operators

How are fees charged when a buyer is found?
Industry‑standard models include:
A success fee (1–5% of transaction value)
A finder’s fee for introductions
A technical advisory fee for data room preparation and due diligence support
Transparent structures protect both sides and maintain professional integrity.

Is it worth doing a feasibility study for gold?
Yes—when the project has real geological potential. A BFS is not a gamble; it is a value‑creation tool. If the resource is too small or poorly defined, it’s better to invest in drilling and resource definition first. When the geology is strong, a BFS can significantly increase project value and attract serious capital.

Mining decisions must be both technical and strategic. A well‑executed feasibility study often determines whether a licence becomes a long‑term asset or remains just a piece of paper.

If you’re serious about moving your mining project forward, understanding these fundamentals isn’t optional—it’s critical. A BFS is your ticket from exploration to enterprise. Got questions? Let’s talk about where your project stands and what’s next.

THE "THINK BLANK" MINDSET: THE FOUNDATION OF INTEGRITY IN MINERAL LABORATORIES

In the high-stakes environment of mineral processing and geochemical analysis, precision is not just a goal; it is an absolute requirement. One of the most critical, yet often overlooked, principles governing this precision is the "Think Blank" mindset. To "Think Blank" means to approach every stage of sampling, preparation, digestion, and analysis with the assumption that contamination, carry-over, or background signal is present unless rigorously proven otherwise. It is far more than a standard Quality Control procedure; it is a fundamental culture of zero contamination tolerance.

The concept originates from the use of blank samples in mineral exploration to detect contamination throughout the analytical workflow. Blanks are designed to identify unwanted analytes introduced from field collection bags, crushing and pulverizing equipment (often referred to as "mill memory"), laboratory reagents, glassware, environmental background, or even analyst handling. Because contamination can infiltrate at any point, the "Think Blank" philosophy demands that laboratory professionals constantly ask themselves: "If this were a blank sample with zero analyte, would my process still produce a clean, near-zero result?" If the answer is no, the process carries an unacceptable contamination risk.

In daily laboratory practice, this mindset manifests through rigorous discipline. It requires cleaning equipment as if the very next sample is a blank, checking reagents to ensure they produce a zero signal, and handling all materials with the awareness that even microscopic dust or residue will compromise a blank. It involves reviewing results by questioning whether a blank would pass under the same conditions and designing workflows that meticulously minimize carry-over between high-grade and low-grade samples. This aligns perfectly with the core principle that blanks must contain no analyte, meaning any detected value is a direct indicator of contamination.

For mineral laboratories, the stakes are exceptionally high. Facilities routinely handle high-grade ores, trace-level pathfinders, and sensitive digestion chemistries under heavy sample throughput. Even the slightest contamination can severely distort gold assays, multi-element ICP results, geochemical anomalies, and ultimately, resource estimation datasets. By adopting the "Think Blank" mindset, laboratories protect the integrity of the entire dataset, ensuring that the results delivered to clients are accurate, defensible, and implicitly trusted.

Ultimately, "Think Blank" is about working as if every sample could be a blank and expecting contamination unless proven otherwise. It demands unwavering discipline in cleaning, handling, and QC protocols, using actual blanks to verify that this mindset is actively working. This culture of zero contamination tolerance is essential for producing the trustworthy mineral assay results that the global mining industry relies upon.

Why Fake-Gold Scams in Africa Keep Trapping Investors — And How to Protect YourselfGold has always carried a certain mythology: stability, wealth, and the promise of high returns. Yet every year, investors from Europe, the USA, and beyond lose millions of dollars to fake-gold schemes across parts of Africa. The stories are well-known, the warnings are everywhere, and still, the cycle continues.As a Mineral Processing Engineer who has spent years operating across Africa and the Middle East, I have seen it all. I have sat in rooms where "discounted gold" was offered with perfectly forged export permits, assay reports, and customs papers. I have watched sophisticated criminal networks use rented offices, fake refineries, and actors posing as government officials to trap unsuspecting buyers.Over the years, I have withstood every form of gold scamming attempted in this industry. More importantly, I have helped numerous investors, project managers, and businesspeople avoid losing their capital to these highly engineered traps.This isn't a story about ignorance; it's a story about psychology and structural weaknesses. Scammers prey on greed, trust, and urgency. They know how to bypass logic with pressure tactics like "the government is changing rules next week" or "the miners need cash today." They use real samples during early meetings, only to switch them with brass or tungsten bars later. To an outsider, everything looks legitimate.Many foreign investors underestimate the gold supply chain. They assume paperwork equals legitimacy or that a local contact is enough. But real gold transactions require licensed exporters, traceable supply chains, independent verification, and strict compliance procedures. Anything outside this framework is a red flag.The hard truth is that these scams continue because they are highly profitable, low-risk for criminals, and target people who believe they are too smart to be scammed.The gold sector in Africa is legitimate and full of incredible opportunities, but the risks are real. If you are looking to invest or trade, you must adopt the same discipline used in any high-value transaction:1. Independent Verification — Never rely solely on the seller's documentation.2. Licensed Exporters Only — Work exclusively through verified, legal channels.3. No Advance Payments — Legitimate deals do not require you to fund the seller's operations upfront.4. Laboratory Testing — Always use reputable, independent facilities (like ISO/IEC 17025 accredited labs) for assaying.5. Zero Tolerance for "Discounted Gold" — In the gold industry, if the deal looks too good to be true, it is.If you are navigating the mineral sector in Africa and need technical assurance or guidance on establishing secure, verifiable supply chains, let's connect. Don't let a highly engineered illusion cost you your investment.

THE FOUNDATION OF TRUST: Ensuring Integrity in Mineral Laboratory Results

By Happiness Nesvinga

The integrity of results in a mineral laboratory is not merely a technical requirement; it is the bedrock upon which multi-million dollar mining and metallurgical decisions are made. When investors, engineers, and project managers review a certificate of analysis, they are placing their trust in a complex chain of events. This trust is earned through strict control of the entire testing process, extending from the initial sample collection in the field to the final data reporting. True integrity is achieved through robust quality systems, validated methodologies, competent personnel, controlled environments, and transparent data management.

If a sample is compromised before it even reaches the analytical instrument, no amount of sophisticated technology can rectify the error. Sample integrity is the absolute foundation of trustworthy results. This begins with a rigorous chain of custody from the field to the laboratory, ensuring correct sample identification and labeling at every step. Furthermore, samples must be maintained under controlled storage conditions to prevent moisture alteration, contamination, or temperature degradation. Standardized sample preparation, encompassing crushing, pulverizing, and splitting, is critical. Laboratories must also implement stringent cleaning protocols and equipment segregation to avoid cross-contamination.

For mineral laboratories, achieving and maintaining ISO/IEC 17025 accreditation serves as the global benchmark for proving technical competence and delivering reliable results. This standard mandates the use of validated methods, traceable calibrations, documented uncertainty, and a rigorous quality management system operated by competent personnel.

Every analytical method employed must be rigorously validated to prove its efficacy within the specific laboratory environment. Method validation encompasses a comprehensive assessment of accuracy, precision, detection limits, linearity, robustness, and matrix effects. Without this fundamental validation, the resulting data cannot be trusted for critical decision-making.

A robust Quality Control system is non-negotiable. A competent mineral laboratory must run quality control checks with every analytical batch. This includes the use of blanks to monitor for contamination, duplicates to verify precision, and Certified Reference Materials to confirm accuracy. Any failure within these quality control parameters must immediately trigger a thorough investigation, corrective action, and subsequent re-analysis.

The integrity of the analytical process collapses if instruments are allowed to drift from their calibrated states. Critical controls include calibration using traceable standards, adherence to routine maintenance schedules, and daily instrument performance checks.

In the modern era, mineral laboratories rely heavily on digital systems, making data integrity and security paramount. Safeguarding data requires secure electronic systems with strict user access controls and comprehensive audit trails.

However, even the most advanced systems will fail without skilled and dedicated people. Integrity depends heavily on continuous training, regular competency assessments, and clear definitions of roles and responsibilities. Personnel must strictly adhere to Standard Operating Procedures within an ethical culture that maintains zero tolerance for shortcuts.

Every action taken within the laboratory must be meticulously documented, time-stamped, attributable, and reviewable. This level of documentation ensures full traceability from the moment of sample receipt to the issuance of the final certificate of analysis. Routine internal and external audits are vital to ensure the system functions as intended.

Ultimately, integrity is not solely a technical endeavor; it is deeply cultural. A mineral laboratory must actively foster an environment of honesty, transparency, and accountability, with absolute zero interference in analytical outcomes. Leadership sets this tone. When a laboratory combines strong sample controls, ISO/IEC 17025-aligned systems, validated methods, robust quality control, calibrated instruments, secure data management, competent staff, full traceability, regular audits, and an ethical culture, it produces results that are accurate, defensible, and implicitly trusted by the global mining industry.
