a. Developments for Mining:

     • In our facilities we have the following state-of-the-art equipment to carry out Mining Analysis:
               o Standardized sample cutters
               o Sifter
               o Ball mill with roller bench
               o Flotation cell with capacity of 1.5, 2.7 and 5 liters
               o Pressure filters
               o Gas chromatography-flame ionization detector (GC-FID)
               o Atomic absorption spectroscopy equipment
               o High-resolution liquid chromatography equipment coupled to various detectors (HPLC-UV-DAD-ELSD)
               o Two-phase foaming equipment

b. Industrial pilots

     • We work with the National Pilotage Center (CNP)

c. Awarded projects financed by Corfo that have been successfully executed

     • 17IDAE-74700: Optimization of the flotation of copper concentrates, through the physicochemical improvement of the recirculation water, via chemical purification                       to obtain water with metallurgical quality

     • 20CV-128331: Development and validation of a reagent that optimizes copper metallurgical performance.

d. Specialty paints
     • Hospital – Antibacterial
               o Formulated for use in construction, mainly in health centers and surfaces that require high safety, this latest generation paint prevents the growth of                                                       microorganisms undesirable to health such as bacteria, fungi and yeasts.
               o It does not contain lead, chromium, mercury or heavy metals, it is not toxic or pollutes the environment.
               o Complies with international standards such as ASTM 5590 and JIS Z 2801 for microorganisms.
               o These paintings were used in the Coronel Hospital as a social project where it was remodeled at no cost.
               o As a company we are very proud of generating and strengthening commitment to the community.

     • Broad spectrum viricide – Covid- Rotavirus and Adenovirus

               o Under the auspices of the most innovative R&D technology and with the help of Geopinturas, we developed a viricidal enamel during the pandemic, which, under                        strict laboratory testing processes, proved to be highly effective against the Corona virus, Rotavirus and the Adenovirus and maintains a durability of action of 9                       months, which provides a certain time to have the necessary security and renewal of the paint.

               o The Viricidal Enamel was evaluated using the infectious SARS CoV-2 virus, the causal agent of COVID 19, under the international standard ISO 21702-2019 (soon                        available).
