Itronics Inc. provided sales guidance for the full year 2021. For full year, the outlook for GOLD'n GRO fertilizer sales is for a significant increase over 2020 due to a greatly reduced impact from Covid-19 and driven by sharp improvements in demand for crops grown in primary California markets. The 2021 outlook for silver sales is for continued improvement due to a combination of on-going recovery optimization and to sharply higher silver and gold prices compared to 2020.
