The Deposit

Arizona's Premier
Pozzolan Resource

The Kirkland deposit sits within a 2,400-acre land package in the volcanic highlands of Yavapai County — one of the most geologically favorable pozzolan-bearing formations in the American West. The deposit was formed by ancient volcanic activity that produced a thick, consistent layer of high-silica rhyolitic ash.

Independent resource estimation confirms over 50 million tonnes of natural pozzolan meeting ASTM C618 Class N specifications — with silica content consistently above 70% and pozzolanic activity index exceeding 75% at 28 days.

The deposit's shallow depth, low strip ratio (under 5%), and proximity to major Western U.S. transportation corridors make it one of the most economically attractive undeveloped pozzolan resources in North America.

Operations

Mine Plan Overview

01

Extraction

Shallow open-pit mining using conventional drill-and-blast or rip-and-push methods. Low strip ratio minimizes waste handling and operating cost.

Strip ratio < 5:1 — among the lowest in the industry
02

Processing

On-site crushing, screening, and air classification to achieve target particle size distribution. No chemical processing or kiln firing required.

ASTM C618 Class N specification achieved through mechanical processing only
03

Distribution

Bulk and bagged product shipped by truck and rail to ready-mix concrete producers, precast manufacturers, and infrastructure contractors across the Western U.S.

Proximity to I-17 and BNSF rail corridor — major Western markets within 1-day transit
