- Mill Capacity: The existing mill has a 1,000 tpd nameplate capacity.
- Previous FS: Considered underground development at 600 tpd, with open pit as supplemental (max 200 tpd).
- New Plan: Aims for 1,000 tpd run-of-mine throughput, utilizing the full mill capacity.
3. Open Pit Potential and Resource Expansion
- Surface Expression: Mineralized structures at PL project to the surface, passing through a swampy area.
- PL North Trend: Identified post-2017 FS, an extension of the main PL deposit not included in previous resources.
- Drilling (5 years until 2021): Demonstrated a continuous mineralized zone over several hundred meters along strike and down dip.
- Notable Intercept (2021): 101 grams per ton (g/t) over 0.5 meters at 208 meters vertical depth, described as a high-grade narrow-vein intercept.
- Economic Viability: Higher gold prices enable a higher strip ratio for efficient and economic mining from surface.
- Data Utilization: Significant data from original mine operations (drill hole database) and Manovva's $20 million investment to date are available for engineering assessment.
- Preliminary Work: Advanced stages of preliminary open-pit mine design, including cone flotation, engineered pit identification, strip ratios, throughput rates, and equipment selection.
4. Updated Technical Studies and Timeline
- Phase One (Target Q1 Next Year):
