Pro resource investors know this rule of thumb.
It helps them analyze exploration-stage juniors and pick potential winners.
It’s the “Rule of 200.” If a company delivers an intercept of 200 meters of one gram per tonne gold (or 100 meters of 2.0 grams per tonne gold; you get the idea), investors immediately put it on their radar.
Auro Metals Inc. has recently delivered several intervals with gram-meter values almost twice as high.
Before we get to the results themselves, here’s the company’s backstory.
Auro Metals has been advancing its Santa Barbara gold-copper project in Ecuador. The project is within the prolific Zamora gold-copper belt.
The project already hosts an Indicated resource of 697,000 ounces of gold and 68 million pounds of copper and an Inferred resource of 3.4 million ounces of gold and 426 million pounds of copper. The company prepared the resource in 2026.
The project’s neighbors include Silvercorp’s Condor project, Lundin Gold’s Fruta del Norte, and Solaris Resources’ Warintza.
Santa Barbara has access to infrastructure, including roads, power, and a skilled workforce.
It is a porphyry system, which means that it has bulk-size potential. The company’s latest drill results delivered assays that start at or close to surface.
Auro has completed 19 drill holes at the property. The first ones delivered world-class wide and near-surface intervals:
Note that holes 54 and 59 delivered results whose gram-meter values are 400 or higher—twice as high as the “Rule of 200” suggests.
We also note that the mineralization encountered by these holes was continuous.
Sometimes companies publish a single impressive-looking drill interval and their stocks see a short-lived surge. Auro Metals has already proven that it can deliver consistent, economic-looking, and wide intervals within a large, gold-rich porphyry close to surface.
In other words, Auro Metals has started delivering world-class intercepts already.
Most importantly, these drill results suggest that mineralization is open both up- and down-dip.
Gold grades in the intervals delivered by Santa Barbara are often higher than those of the neighboring porphyry-style deposits.
For example, the Cangrejos gold-copper porphyry has a gold grade of 0.46 g/t in its Measured and Indicated resources. Cascabel’s Indicated resources feature gold grades of 0.28 g/t. Warintza, another porphyry, has a gold grade of just 0.04 g/t in its mineral reserves.
Some operating mines feature ore grades close to Santa Barbara’s. For example, Detour Lake, operated by Agnico Eagle Mines, is an open pit mine processing ore with an average grade of 0.7 g/t gold. Fort Knox, owned by Kinross Gold, processes material with an average grade of about 0.4 g/t gold.
The company keeps drilling. We expect more drill results to be published shortly.
At the end of March, the company had C$16.9 million in cash to fund its work at Santa Barbara.
The market has noticed Auro Metals’ success. Since completing the acquisition of the project on May 13, the company’s share price has increased by about 15%.
The company’s management and insiders have plenty of skin in the game. Insiders and associates hold 47.4% of Auro Metals’ shares. Silvercorp, a C$3 billion miner, holds another 28%. In other words, both the management team and some of the most recognizable companies in the resource space are deeply invested in Auro Metals’ success.
We will not be surprised to see a steady stream of press releases from Auro Metals. Santa Barbara remains open in all directions, so there is plenty of footprint to explore further.
It is also open at depth. As we said earlier, some drill holes ended in mineralization, suggesting there may be more valuable material lying deeper.
The company plans to wrap up its Phase 1 drilling campaign in Q3 and immediately start its Phase 2 campaign.
Given what Auro Metals has delivered so far, investors should be watching this stock.
