Nobel Maps a Bigger Cuprita Target Ahead of Next Drills

Nobel Resources Corp. (TSXV: NBLC; OTCPK: NBTRF) said final 3D inversion results from a Quantec pole-dipole induced polarisation survey identified a large, continuous chargeability anomaly matching the mapped lithocap at its Cuprita copper project and extending the target area south and east, as the company set out its next drill phase and began initial exploration at Janett.

Nobel Resources Corp. (TSXV: NBLC; OTCPK: NBTRF) has told the market where it intends to point the drill rig next at its Cuprita copper project, and the answer is a larger area than the one it has been working. The company said final geophysical results from a pole-dipole induced polarisation survey run by Quantec produced a 3D inversion model showing a large and continuous chargeability anomaly that lines up with the mapped lithocap at Cuprita and pushes the target area to the south and east of the ground explored so far.

Alongside the Cuprita plan, Nobel said it has begun initial exploration at its Janett project. The two properties are now being presented together as the company's near-term exploration programme.

What the Quantec survey actually measured

Induced polarisation is a workhorse geophysical technique in copper exploration. A current is passed into the ground and the decay of the voltage is measured after it is switched off; rocks holding disseminated sulphide minerals hold charge longer than barren rock. That property is called chargeability, and a chargeability anomaly is a volume of ground that behaves as though it contains sulphides. The pole-dipole array Quantec used is one of the standard configurations for pushing that measurement deeper than a simple dipole-dipole survey can reach.

The 3D inversion model is the step that turns raw readings into geometry. Instead of a set of two-dimensional pseudo-sections along survey lines, the inversion solves for a block model of the subsurface, so the anomaly can be seen as a shape with depth and continuity rather than a smear on a profile. Nobel's description of the result — large and continuous — is the language explorers use when the anomaly does not break up into isolated patches, which is what makes it drillable as a single target rather than a scatter of guesses.

The correlation with the mapped lithocap is the part geologists will focus on. A lithocap is the leached, silica- and clay-altered blanket that sits above many porphyry copper systems, formed by acidic fluids venting toward surface. It is a signpost, not an orebody. When a lithocap at surface sits directly over a chargeability response at depth, the two datasets are pointing at the same system from different directions. That is the standard argument for drilling.

Shallow cover south of the known lithocap

The genuinely new information in Nobel's INN Precious Metals announcement is the ground to the south. The company said the newly identified anomaly there sits beneath shallow overburden cover and represents an extensive untested area for potential mineralisation.

Shallow cover matters in two directions. It explains why the area was not chased earlier: surface mapping and rock chip sampling cannot see through overburden, so a target under even a thin blanket of transported material stays invisible to conventional prospecting. It also means the cost of testing it is lower than a deeply buried target would imply, because the drill does not have to spend metres punching through waste before it reaches rock that carries information.

The trade-off is that geophysics alone does not distinguish copper sulphides from pyrite, graphite or other conductive nuisances. Chargeability tells you something is there; only the core tells you what. That is the risk sitting in front of the next programme, and it is the standard risk of every IP-driven drill campaign.

A microcap tape with almost no cushion

Nobel's US over-the-counter line reflects how thinly this kind of story trades. NBTRF was quoted at 0.01 as of 15:29 GMT on 9 September 2026, down 53.60% on the day against a prior close also rounded to 0.01, with the day's range printing flat at that same level. At penny quotes on an OTC Pink line, a single rounding tick produces a headline percentage move that carries almost no information about the business; the TSX Venture listing under NBLC is where price discovery for the company genuinely happens.

The wider tape was soft the same session. The S&P 500 tracker traded at $761.43, off 0.59%, the Nasdaq 100 proxy at $714.73, down 0.51%, and the Dow tracker at $523.83, down 0.80%. A broad risk-off day is not a helpful backdrop for a junior explorer trying to convert a geophysical result into financing.

The numbers that will decide this

Nobel did not, in the material summarised here, attach metreage, hole counts, a start date or a budget to the Cuprita programme, and it did not put a figure on the combined area of the lithocap and chargeability anomaly. Those are the disclosures that turn an exploration plan into something an investor can size, and they are the ones to look for next.

Three specific items are worth tracking:

• Programme scope. Total metres, number of holes and planned depths, which together set the cash requirement and the timeline to first assays.
• Funding. Whether the drilling is covered by cash on hand or requires a raise. For a company trading at penny levels, dilution terms can matter more to the share price than the drill results themselves.
• Janett detail. What initial exploration at Janett consists of — mapping and sampling, geophysics, or drilling — and how it is sequenced against Cuprita for crew and rig availability.

Copper exploration has a favourable demand narrative behind it, and lithocap-plus-IP targets under shallow cover are exactly the kind of setup that attracts drill capital. But a chargeability anomaly is a hypothesis. Until Nobel publishes assays from holes into the southern extension, the company has expanded the size of its question, not answered it.

Frequently asked questions

What did Nobel Resources announce about Cuprita?

Nobel Resources Corp. said it received final geophysical results from a pole-dipole induced polarisation survey completed by Quantec at its Cuprita copper project. Quantec's 3D inversion model highlighted a large and continuous chargeability anomaly corresponding with the mapped lithocap, extending the target area south and east of where exploration has been concentrated to date. The company also set out its next phase of drilling.

What is an induced polarisation chargeability anomaly?

Induced polarisation surveys push current into the ground and measure how long rock holds charge after the current stops. Rocks containing disseminated sulphide minerals hold charge longer, producing a chargeability anomaly. It indicates that conductive or chargeable material is present at depth, but it cannot distinguish copper sulphides from pyrite or graphite. Only drilling and assays confirm what the anomaly actually contains.

Why does the lithocap matter at Cuprita?

A lithocap is a leached, silica- and clay-altered blanket formed by acidic fluids venting above many porphyry copper systems. It is a surface signpost rather than an orebody. When a mapped lithocap sits directly over a chargeability anomaly, two independent datasets point at the same buried system, which is the conventional geological argument for committing drill metres to the target.

What is significant about the shallow overburden cover?

Shallow cover explains why the southern area was not tested earlier, since surface mapping and rock sampling cannot see through transported material. It also lowers the cost of testing, because drill holes do not need to pass through large thicknesses of barren waste before reaching rock that carries geological information. Nobel described the area as extensive and untested.

Where does NBTRF trade and what is the price?

Nobel Resources trades on the TSX Venture Exchange under NBLC and over the counter in the United States as NBTRF. The OTC line was quoted at 0.01, down 53.60% on the day, as of 15:29 GMT on 9 September 2026. At penny quotes a single rounding tick creates outsized percentage moves, so the Venture listing is the more meaningful reference.

What should investors watch next?

The disclosures that would let investors size the opportunity have not yet been published: total metres, hole count and depths for the Cuprita drill programme, its start date and budget, and how it will be funded. Also relevant is the scope of initial exploration at the Janett project and how the two programmes are sequenced for rig and crew availability.
