Mineral Deposit Chemical Analysis

50 million tons reserve

The KMI mineral reserve has been tested by Triclinic Labs, a leading provider of comprehensive solid-state chemical development and testing services.

The purity of our mineral has made it a trusted source by governments & businesses internationally.

Proven 97% purity

We have conducted multiple deposit samples and continue to perform ongoing testing. All results have shown our deposit to be, by far, the highest in North America, perhaps even the world.

Naturally occurring zeolites are rarely found in such a pure form and are often contaminated by varying degrees of minerals such as metals, quartz or clays.

KMI Zeolite Core Sample Results

Two separate sample batches were taken. Each consisting of 50 random core samples.

The two clinoptilolite zeolite powder samples were received from KMI Zeolite Inc. for X-ray powder diffraction (XRPD) measurement under standard conditions. A single aliquot was taken from one of the samples and mounted using a low background silicon sample holder. The powder was placed into the holder to achieve a flat and level surface. Information concerning the samples are presented in Table 1.

Figure 2: Measured XRPD data for powder sample compared with previous data

Visual inspection of the data overlay in Figure 2 indicates that the new powder sample is essentially the same as the previous samples with respect to the X-ray powder diffraction response. Some addition weak peaks were observed in the latest XRPD data.

Analysis

Figure 3: Crystalline phase identification for data set RX1-15547
Figure 4: Small unidentified peaks described by the montmorillonite mineral

A crystalline peak search was performed for the observed data file and the resulting peak list matched against the COD crystal structure data base using the software MDI- Jade2010 (V 5.0.0).

The crystalline phase identification results are presented in Figure 3.

Clinoptilolite (PDF# 98-900-9578) was identified as being the primary crystalline phase with Montmorillonite (PDF# 98-110-0106) identified as a possible minor phase.

Three small peaks not identified by clinoptilolite are described by the mineral phase montmorillonite; see Figure 4.

An additional mineral phase that may appear along with the clinoptilolite- heulandite zeolites is Stilbite.

To determine whether these mineral forms were present along with the clinoptilolite and to determine whether the unidentified peaks were best described by montmorillonite or phlogopite, a Rietveld semi-quantitative analysis was performed using Jade2010.

For each Rietveld analysis, the crystalline minerals Clinoptilolite-Ca, Montmorillonite, Phlogopite and Stilbite-Ca were included within the starting model. The results of the Rietveld semi-quantitative analysis are presented in Figure 5.

The Rietveld analysis returned quantitative values for both Phlogopite and Stilbite-Ca that were below detection limits. The semi-quantitative results are summarized in Table 4.
