SEOUL, South Korea, Jan. 16, 2024 /PRNewswire/ -- Synthetic, non-biodegradable plastics are major sources of environmental pollution and have prompted a rising interest in sustainable, biodegradable alternatives derived from natural polymers. "Tara gum," derived from the seeds of the tara tree (Caesalpinia spinosa), stands out as a promising solution. This natural, water-soluble substance contains polysaccharides (complex carbohydrates), including the widely used "galactomannan," which is employed in coatings, edible films, and as a stabilizer and thickener. The biocompatibility, biodegradability, and safety of tara gum also make it valuable in industries like food and drug delivery. Moreover, the adaptable nature of the groups within tara gum polysaccharides renders it valuable for tailoring physicochemical and mechanical properties for specific applications.

Key Points: 
  • "Tara gum," derived from the seeds of the tara tree (Caesalpinia spinosa), stands out as a promising solution.
  • The biocompatibility, biodegradability, and safety of tara gum also make it valuable in industries like food and drug delivery.
  • Moreover, the adaptable nature of the groups within tara gum polysaccharides renders it valuable for tailoring physicochemical and mechanical properties for specific applications.
  • "The physicochemical property of tara gum and its products can be enhanced using various kinds of monomers, crosslinkers, or other polysaccharides.

VANCOUVER, British Columbia, Feb. 23, 2022 (GLOBE NEWSWIRE) -- Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the “Company”) is pleased to announce the final tranche of reverse circulation (“RC”) drill results from the 2021 program in the Rangefront Focus Area (“RFA”) at the Black Pine oxide gold deposit in southern Idaho. RFA drilling resumed in January 2022 with three RC and one core rig and an additional 9,600 meters (“m”)  in 34 holes have now been drilled to-date with assays pending.

Key Points: 
  • LBP514: 0.98 g/t Au over 85.3 m, including 1.56 g/t Au over 27.4 m
    VANCOUVER, British Columbia, Feb. 23, 2022 (GLOBE NEWSWIRE) -- Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (Liberty Gold or the Company) is pleased to announce the final tranche of reverse circulation (RC) drill results from the 2021 program in the Rangefront Focus Area (RFA) at the Black Pine oxide gold deposit in southern Idaho.
  • In 2021, Liberty Gold drilled a total of 28,048 m in 74 holes into a 1 square kilometer (km2) area within the RFA, and mineralization remains open for lateral extension to the north, northwest and east.
  • Later in 2022, we are looking forward to testing the northeastern and eastern extent of the RFA where shallow historical drilling shows the presence of gold mineralization.
  • The high-grade core has been extended 250 m to the east, merging with mineralization associated with the original Rangefront resource pits.
