Flotation Concentrate Shipped
The final phase of work on the Pardo bulk sample is underway. The remaining concentrates have been sampled and shipped to the Horne Smelter (Glencore). Assays should be available in a couple of weeks that will enables us to complete the 007 Zone grade reconciliation.
Second Concentrate Shipment Confirmed
We now have a contract with Glencore to process our Pardo flotation concentrates. The material should soon be on its way to the smelter. Step-by-step we are making progress towards our goal, as Confucius once said: “It does not matter how slowly you go so long as you do not stop”.
First Concentrate Sale Complete
The gravity concentrates have been sold and shipped. This is an important first step for Inventus (we’ve experienced many firsts recently). Now the focus is on shipping the flotation concentrates as soon as we can.
007 Bulk Sample Update
Hello Everyone,
I wanted to let you know why we don’t have final numbers from the 007 bulk sample yet. I expected that by the end of March we would have enough data to release a preliminary estimate, but we are not there quite yet.
Let me explain:
The mill is set up to produce two types of concentrates. The first method uses gravity separation (basically a centrifuge) to concentrate heavy particles (ie. gold and other metallics).
The second method is flotation, which causes very small metallic particles in a slurry with water to “float” to the surface where they are collected. Some of the water is removed and then the concentrate is filtered to produce a wet “cake”.
Gravity concentrates are typically very high grade and small quantity. The process is very selective because the equipment is only designed to separate 1 to 2 tonnes of concentrates per day of milling. Gravity concentrates initially have high moisture, they need to dry out some before they can be weighed and sampled, which we have now done.
Flotation concentrates are lower grade and much higher quantity. One of the main reasons we don’t have a firm result from the bulk sample yet is that we don’t have an accurate weight or assay for the flotation concentrate. The only method available to accurately weigh the product is to load it into trucks and put them on a scale (ie when we sell it). Sure, we have a ballpark number, but that’s not even close to good enough for a reportable figure.
So we have a good handle on the gold in gravity concentrates. We also have a good handle on the grade in the tailing (the gold that was lost in the process), and this indicated the mill was highly efficient at separating the gold in the bulk sample (great news).
More good news, we are close to shipping the gravity concentrates to the end-buyer, and once a few more assay results are in, we expect to do the same with the flotation concentrates. This will enable us to properly weigh and sample the flotation concentrates. It’s just taken us a little longer than expected to get to this point.
The concentrates we produced are nearly free of penalty elements (such as arsenic and bismuth), which makes them marketable anywhere in North America, Europe and Asia.
Planning is already occurring for the next phase of bulk sampling this summer.
I hope that helps everyone understand where we are.
All the best,
Stefan Spears
Milling Complete
The milling of the bulk sample was complete on February 25th and the circuit is now being cleaned out. Assays have been sent to a third-party lab so the reconciliation process can begin. Final assays will take a little while - yes, we understand waiting for assays is a real drag. Below is a photo taken by Stefan on Feb 18th of a splash of colour panned from the gravity concentrate.
Bulk Sample Milling to Start Up Tomorrow (Feb 15th)
Pleased to announce that processing of the 007 bulk sample is expected to start up on schedule tomorrow. The run is anticipated to take <10 days.
Half Way There
3,000 t of the total 6,000 t of mineralized material have now been delivered from Pardo to the Redstone Mill in Timmins.

Cobalt Hill Drilling Update
Drilling at the Cobalt Hill Au-Co-Ni prospect is going well. Two holes of the 4,000 m program have been complete with both intersecting the target sulphide breccia.
Cobalt Hill - IP Anomaly Visualization
January 2022 drill target at Cobalt Hill. 500m x 600m IP chargeability anomaly open at depth. Hole CH-21-02 (from Spring 2021) just skimmed the edge and return a decent intercept.

Mini Bulk Sampling Phase 2 Update
The 2nd phase of mini bulk sampling, consisting of 22 one cubic metre pits from Eastern Reef, Trench 1 and Trench 2 is well underway. The pits have been drilled, blasted and excavated into bulk bags. Assays from the mini bulk samples will provide more accurate grade estimation of the larger scale 50,000 tonne bulk sampling program.

Exploration Underway at Inventus’ High-Grade Palladium Property
In 2019 it was identified that the high-grade mineralization at the Rathbun Property is related to the same geology that formed the world-class Ni-Cu-PGE ore deposits around Sudbury. Since this discovery the property has lain dormant until it was acquired by Inventus in January of 2021. The Rathbun Property was mined in the 1890’s where a historic shaft and rusty sulfide mineralization is located on the shore of Rathbun Lake. Sampling of the semi-massive sulfide mineralization around the shaft by Inventus returned values up to 22% copper, 62 g/t palladium, 18 g/t platinum, 7 g/t gold and 0.5% nickel.
A review of the historic exploration on the property has provided clues as to where the Sudbury offset structure many continue. Inventus is currently conducting surface trenching in these key areas in preparation for drilling.
Mini Bulk Sample Crushing
Our 3 tonne mini bulk samples from the 007 zone are being crushed and split today. Results are expected in July.
Pardo Mini Bulk Sampling Update
Inventus' mini bulk sampling program is well underway with the first batch of test sampling being delivered for crushing and assay.
